Exhibit 5 

Liquid Removal Test Procedure 

Definitions common to all certification and test procedures are in: 

 D-200 Definitions for Vapor Recovery Procedures 

For the purpose of this procedure, the term "ARB" refers to the California Air Resources Board, 

and the term "Executive Officer" refers to the ARB Executive Officer or his or her authorized 

representative or designate. 

1. PURPOSE AND APPLICABILITY

1.1 This procedure is used to quantify the removal rate of liquid from the vapor passage 

of a Phase II balance system hose equipped with a liquid removal device. This 

procedure provides a method to determine compliance with the liquid removal 

requirements specified in ARB Executive Orders VR-207 and VR-208 and any 

subsequent amendments or revisions. 

2. PRINCIPLE AND SUMMARY OF TEST PROCEDURE

2.1 This test procedure provides two options to determine the compliance of liquid 

removal devices. Under option 1 (short version), liquid in the vapor path of a coaxial 

hose is drained and measured. If the volume of liquid drained equals or exceeds 25 

ml, a liquid removal test is conducted. For those hoses with less than 25 ml drained, 

no further testing is required. Under option 2 (long version), all hoses are evaluated 

regardless of the volume of liquid drained. Option 2 includes a prewetting and wall 

adhesion step. Both options test the liquid removal device by introducing gasoline 

into the vapor path of the coaxial hose through the nozzle bellows. After 7.5 gallons 

of gasoline is dispensed, the amount of gasoline remaining in the hose is measured 

and the liquid removal rate is determined. The district shall specify which testing 

option is to be used. 

Caution: When draining liquid from the vapor side of the hose, make 

sure the dispenser is not activated. The nozzle vapor valve is 

on the same stem as the fuel valve. To drain gasoline from the 

vapor side of the hose, the fuel lever must be engaged. If the 

dispenser is activated, gasoline in the fuel hose may be 

pressurized when engaging the fuel lever.

3. BIASES AND INTERFERENCES

3.1. Slits or tears in the hose or nozzle vapor path may bias the results towards compliance.

3.2. This test shall not be conducted on any fueling point where the hanging hardware is 

defective as identified in Exhibit 2.
-2- 

Emco Phase II EVR System with Hirt Thermal Oxidizer Including INCON ISD, Exhibit 5 – VR-208-A 

3.3. Any spillage of gasoline invalidates the test for any volumes that are required to be 

measured or recorded.

3.4. A breach of the inner product hose may introduce additional gasoline into the outer 

vapor path resulting in a larger volume drained than introduced.

3.5. Not having the liquid extraction device (indicated by the mark on the outside of the hose) 

at the bottom of the hose loop during liquid removal testing, as shown in Figure 1, will 

bias the results towards failure.

3.6. The test procedure requires the use of Emco’s nozzle spout plug, P/N 494635EVR 

as shown in Figure 2. This tool is used to plug the spout when draining liquid from 

the vapor side of the hose. Not plugging the spout may bias the results towards 

failure. Nicks, cuts, or tears in the plug seal will bias the results towards failure. 

3.7. Dispensing rates not between 6.0 and 10.0 gallons per minute (GPM) invalidates the 

test.

4. SENSITIVITY, RANGE, AND PRECISION

4.1 The range of measurement of the liquid removal rate is dependent upon the range of 

the graduated cylinder used for testing.

4.2 To ensure precision, graduated cylinder readings shall be measured at the liquid 

level meniscus.

5. EQUIPMENT

5.1. Nozzle Spout Plug: Use Emco’s spout plug, P/N 494635EVR (Figure 2). 

5.2. Stopwatch. Use a stopwatch accurate to within 0.2 seconds.

5.3. Funnels. Large and small gasoline compatible, non-breakable, funnels with 

dimensions similar to those as shown in Figure 3, or equivalent. 

5.4. Graduated Cylinders. Gasoline compatible, non-breakable 0-25ml, 0-100ml, 0-250 

ml, and 0-500 ml graduated cylinders with stable base plates. The 25ml cylinder 

may be necessary to quantify volumes of liquid less than 20 ml.

5.5. Gasoline Test Tank. (Optional) A portable tank, meeting fire safety requirements for 

use with gasoline, may be used to receive the gasoline dispensed during testing. 

The tank shall have sufficient volume so that at least 10.0 gallons may be dispensed 

prior to activating the primary shutoff mechanism of the nozzle. When using a 

gasoline test tank, ensure that a ground strap is used and that it is properly 

connected to an acceptable ground. To minimize testing-related emissions, 

vehicle refueling events should be used for this procedure whenever feasible. 

5.6. Traffic Cones. Use traffic cones to encircle the area where testing is conducted. 
-3- 

Emco Phase II EVR System with Hirt Thermal Oxidizer Including INCON ISD, Exhibit 5 – VR-208-A 

5.7. Field Data Sheet. Use the appropriate data sheet to record liquid removal test 

information. Forms 1 and 2 serve as examples; districts may require modified 

versions. 

5.8. Gasoline Container. Use a portable fuel container equipped with a tight fitting cap, of at 

least 1.0 gallon capacity. 

NOTE: THIS TEST PROCEDURE PROVIDES TWO OPTIONS TO DETERMINE 

COMPLIANCE OF LIQUID REMOVAL DEVICES. THE DISTRICT SHALL SPECIFY WHICH 

TESTING OPTION IS TO BE USED 

6. OPTION 1 (SHORT VERSION) 

PRE-TEST PROCEDURE 

6.1 Verify that the 500 ml graduated cylinder is empty. Position the large funnel into the 

graduated cylinder. 

6.2 Remove the nozzle from the dispenser. Do not activate dispenser! Install 

Emco’s spout plug, P/N 494635EVR in the tip of the spout (Figure 2). Carefully tilt 

the spout into the funnel/graduated cylinder assembly.

6.3 Lower the nozzle and funnel/graduated cylinder assembly as close to the ground as 

possible. “Walk out” the hose while keeping the nozzle lowered and hose fully 

extended. The hose shall slope downward from the dispenser toward the nozzle.

6.4 Do not activate dispenser! Open the nozzle’s vapor check valve by 

compressing the bellows and engaging the fuel lever. Allow 20 seconds for all liquid 

to drain. Use caution to avoid spillage.

6.5 Remove Emco’s spout plug and return the nozzle to the dispenser and measure the 

volume of liquid drained. If the volume drained is less than 200 ml, transfer the liquid 

into an appropriately sized graduated cylinder. For example, if 40 ml of liquid was 

drained, use the 100 ml graduated cylinder to take the measurement.

6.6 Record the amount of liquid drained on Form 1 (“PRE-TEST”).

6.7 If the volume drained is greater than or equal to 25 ml, proceed to Section 6.8 of the 

procedure. Hoses with greater than 25 ml drained are considered to be pre-wetted. 

If the amount drained is less than 25 ml, proceed to the next nozzle/hose to be 

evaluated and repeat Section 6.1-6.6 

TEST PROCEDURE (FOR HOSES WITH GREATER THAN 25 ML DRAINED) 

6.8 Pour 150 ml to 175 ml of gasoline into the 250 ml graduated cylinder. Measure and 

record this volume on Form 1 (VI).

6.9 Remove the nozzle from the dispenser and position the nozzle upright so that the 
-4- 

Emco Phase II EVR System with Hirt Thermal Oxidizer Including INCON ISD, Exhibit 5 – VR-208-A 

spout is in a vertical position. Do not activate dispenser!

6.10 Open the nozzle’s vapor check valve by compressing the bellows and engaging the 

fuel lever. Carefully insert the stem of the small funnel between the bellows and 

nozzle spout.

6.11 Pour the measured volume into the vapor path of the hose. Use caution not to spill 

the gasoline. Remove the small funnel after the gasoline has been introduced. 

6.12 Insert the nozzle into a vehicle or test tank fill pipe.

6.13 Find the mark on the outside of the hose which indicates the location of the liquid 

pick-up device. Ensure the mark is at the bottom of the hose loop when dispensing 

as shown in Figure 1. This can be accomplished by lifting up the back of the hose, 

adjusting nozzle position, or adjusting the test tank position.

6.14 Dispense 7.5 (±0.5) gallons at the highest possible flow rate by holding the nozzle 

lever in the maximum handheld position. Use a stopwatch to measure the time 

elapsed while dispensing. Record the volume of fuel dispensed (G) and the elapsed 

time (T) on Form 1. Return nozzle to the dispenser. 

6.15 Calculate the dispensing rate using the equation below. If the dispensing rate is not 

between 6.0 and 10.0 gallons per minute (GPM), the test results are invalid.

Where: 

 GPM = dispensing rate (in gallons per minute) 

 G = gallons of fuel dispensed 

 T = number of seconds required to dispense 

6.16 Using the 250 ml graduated cylinder and large funnel, carefully drain the remaining 

liquid from the vapor path of the hose as described in Section 6.1 through 6.5 (make 

sure dispenser is not activated and spout plug is installed before 

draining liquid!). Record this quantity on Form 1 (VF). 

6.17 Use Equation 9.1 to calculate the liquid removal rate for all the applicable hoses 

tested.

6.18 If the liquid removal rate is less than 5.0 ml/gallon, but greater than or equal to 4.5 

ml/gallon, repeat the test two additional times and average the three results.

7.14 Insert the nozzle into a vehicle or test tank fill pipe. 

7.15 Find the mark on the outside of the hose which indicates the location of the liquid 

pick-up device. Ensure the mark is at the bottom of the hose loop when dispensing 
-6- 

Emco Phase II EVR System with Hirt Thermal Oxidizer Including INCON ISD, Exhibit 5 – VR-208-A 

as shown in Figure 1. This can be accomplished by lifting up the back of the hose, 

adjusting nozzle position, or adjusting the test tank position. 

7.16 Dispense 7.5 (±0.5) gallons at the highest possible flow rate by holding the nozzle 

lever in the maximum handheld position. Use a stopwatch to measure the time 

elapsed while dispensing. Record the volume of fuel dispensed (G) and the elapsed 

time (T) on Form 2. Return nozzle to the dispenser. 

7.17 Calculate the dispensing rate using the equation below. If the dispensing rate is not 

between 6.0 and 10.0 gallons per minute (GPM), the test results are invalid. 

Where: 

 GPM = dispensing rate (in gallons per minute) 

 G = gallons of fuel dispensed 

 T = number of seconds required to dispense 

7.18 Using the 250 ml graduated cylinder and large funnel, carefully drain the remaining 

liquid from the vapor path of the hose as described in Section 7.5 through 7.8 (make 

sure dispenser is deactivated and spout plug is installed before draining 

liquid!). Record this quantity on Form 2 (VF). 

7.19 Open the nozzle’s vapor check valve by compressing the bellows and engaging the 

fuel lever. Do not activate dispenser! Carefully insert the stem of the small 

funnel between the bellows and nozzle spout 

7.20 Use the 250 ml graduated cylinder and small funnel to pour 150 ml of gasoline into 

the vapor passage of the hose. Dispense no gasoline. 

7.21 Using the 250 ml graduated cylinder and large funnel, completely drain the gasoline 

from the vapor passage back into the graduated cylinder as described in Section 7.5 

through 7.9 (make sure dispenser is deactivated and spout plug is 

installed before draining liquid!). 

7.22 Subtract the volume drained (value from Section 7.21) from the volume added (value 

from Section 7.20). This value represents the volume of gasoline lost due to wall 

adhesion. The purpose of the wall adhesion value is to quantify the amount of 

gasoline lost to evaporation from transfer to and from the graduated cylinders and 

adhesion of liquid to vapor passage surfaces in previous measurements. Record 

this quantity on Form 2 (VW). 

7.23 Use Equation 9.2 to calculate the liquid removal rate for all the applicable hoses 

tested. 

7.24 If the liquid removal rate is less than 5.0 ml/gallon, but greater than or equal to 4.5 

ml/gallon, repeat the test two additional times and average the three results.

1. PURPOSE AND APPLICABILITY

This test procedure verifies the operational status of the Hirt VCS 100 Processor and 

Indicator Panel. 

The station may remain open (normal fuel dispensing) while conducting this procedure. 

2. PRINCIPLE AND SUMMARY OF TEST PROCEDURE 

The Hirt VCS 100 Processor is designed to activate (e.g. thermally oxidize vapors) when 

the underground storage tank (UST) ullage pressure exceeds a nominal -0.40 inches 

water column (“w.c.). Processor activation will be verified by exposing the processor’s 

internal vacuum sensor/switch to an atmospheric pressure input. The processor should 

activate, the Hirt Indicator Panel Processing lamp should light and the Incon VRM 

Console warning lamp should light. The Incon VRM Console should also post a VRM 

alarm. 

3. BIASES AND INTERFERENCES 

3.1 This test is only valid when total ullage is 70% or less than capacity of GDF storage 

tanks. 

3.2 At least 24 hours must have elapsed after any tests that introduce air and/or 

nitrogen into the vapor spaces, such as, but not limited to TP-201.3 (including 

Exhibit 4), TP-201.4 (including Exhibit 6) and Exhibit 5. 

3.3 There shall be no Phase I bulk product deliveries into or out of the storage tank(s) 

within the three (3) hours prior to the test or during performance of this test

Exhibit 10 

INCON ISD System Vapor Flow Meter Operability Test Procedure 

Definitions common to all certification and test procedures are in: 

D-200 Definitions for Vapor Recovery Procedures 

For the purpose of this procedure, the term “ARB” refers to the California Air Resources 

Board, and the term “Executive Officer” refers to the ARB Executive Officer, or his or 

her authorized representative or designate. 

1. PURPOSE AND APPLICABILITY 

1.1 This procedure is used to verify the setup and operation of the INCON ISD 

System Vapor Flow Meter certified for use with the EMCO Balance Phase II 

EVR System installed at gasoline dispensing facilities (GDF). This procedure is 

applicable to ARB Executive Order (EO) VR-208-A. 

2. PRINCIPLE AND SUMMARY OF TEST PROCEDURE 

2.1 A tight fitting Balance Nozzle Adapter is placed on the spout of the dispensing 

nozzle. The adapter, which allows the introduction of nitrogen into the nozzle 

vapor collection path, is connected to the outlet side of a reference volume gas 

meter. The inlet side of the reference volume gas meter is connected to a flow 

meter (rotometer) that is attached to a high pressure nitrogen cylinder and a 

pressure regulator. See Figure 2. Nitrogen is introduced through both the 

reference volume gas meter and the INCON ISD System Vapor Flow Meter. 

Nitrogen flow volumes from both meters are then compared with each other to 

determine the accuracy of the INCON ISD System Vapor Flow Meter. This 

process is repeated for the remaining INCON ISD System Vapor Flow Meter 

equipped dispensers at the GDF. 

2.2 The test is conducted with the pressure/vacuum (P/V) vent valve(s) installed on 

the storage tank vent pipes, the Hirt VCS-100 processor turned off, the product 

emergency shut-off valve (product sheer valve) of the dispenser in the closed 

position, and the Phase I vapor poppet opened to atmosphere. 

2.3 The test procedure requires no modifications to the GDF being evaluated. 

2.4 The fueling point on the opposite side of the fueling point being tested must be 

blocked off so that dispensing is not allowed.

3. BIASES AND INTERFERENCES 

3.1 Nozzle spouts that are damaged such that the Balance Nozzle Adapter cannot 

fit over the nozzle spout preclude the use of this test. 

3.2 Phase I vapor poppet must be opened to allow the ullage pressure to equalize 

with atmosphere pressure. Failure to do so may bias the results toward 

noncompliance. 

3.3 Drain or remove any liquid gasoline that may be in the nozzle and the vapor 

return path of the hose. Failure to drain this gasoline liquid will bias the test 

toward noncompliance. 

3.4 The O-ring in the Balance Nozzle Adapter and the face seal (boot face) of the 

nozzle that is not properly lubricated may bias the results toward 

noncompliance. 

3.5 Failure to turn off the Hirt VCS-100 processor will bias this test toward 

noncompliance. 

3.6 The nominal inside diameter of the flexible hose and fittings not between 0.75 

and 1.00 inches will bias the test toward noncompliance. 

4. SENSITIVITY, RANGE, AND ACCURACY 

4.1 The maximum rated capacity of the reference gas volume meter shall be at least 

800 CFH and not greater than 3000 CFH. 

4.2 The minimum rated capacity of the reference gas volume meter shall be 25 

CFH. 

4.3 The minimum readability of the reference gas volume meter shall be 0.01 cubic 

feet. 

4.4 Accuracy of the reference gas volume meter, determined during calibration, will 

be ± 5 percent of the meter reading.

6. PRE-TEST PROCEDURES

6.1 Disabling power to the Hirt VCS-100 vapor processor. Locate the Hirt VCS100 indicator panel and disable power by turning the ON/ OFF switch to the 

OFF position. Disabling the power to the processor will trigger a vapor 

processor warning alarm indicated by a yellow light on the INON ISD console. 

The testing contractor must document this event in the GDF’s maintenance 

records kept on site. 

6.2 Opening the Phase I vapor poppet to atmosphere. Locate the Phase I EVR 

vapor poppet on the 87 grade tank and remove the dust cap. Open the vapor 

poppet to atmosphere by using a modified dust cap. 

6.3 Closing the product emergency shut-off valve (product sheer valve) to disable 

dispensing. Remove the dispenser covers and locate the emergency shut-off 

valve for the 87 grade gasoline. Locate the hex bolt and linkage arm on the side 

of the emergency shut-off valve. Use index finger to pull the linkage arm away 

until it clears the latch and the poppet snaps closed. Verify that the poppet is 

closed by attempting to dispense fuel in to a gasoline approved container. 

Note: The test requires that the nozzle handle be squeezed and liquid 

product must not flow from the dispenser. 

6.4 Verify leak integrity of test assembly. Conduct a pre-test leak check of the 

Balance Nozzle Adapter, the reference gas volume meter, and the adapter 

supply hose by connecting the Balance Nozzle Adapter to a surrogate spout as 

shown in Figure 1. Turn the ball valve in Figure 1 to the closed position. Raise 

the test assembly pressure to 5.00” ±0.50” WC using a squeeze bulb. There 

shall not be a pressure drop of more than 1.00” WC from the above starting 

pressure for 30 seconds from the start of the test. If the leak test passes, 

proceed with the testing. If the leak test fails, proceed to isolate the source of the 

leak by pressurizing the test equipment again. Apply liquid leak detector 

solution on interfaces and other potential leak sources and watch for the 

formation of bubbles. Once leak(s) are repaired, repeat the leak test procedure. 

Note: Leak checks shall be conducted in a shaded area or away from 

direct sunlight. Leak checks may be conducted during the testing to 

ensure leak integrity of test equipment 

6.5 Assemble the equipment as shown in Figure 2: INCON ISD System Vapor Flow 

Meter Test Assembly. Leave the Balanced Nozzle Adapter off of the nozzle at 

this time. Do not enable the dispenser to dispense product. Remove nozzle and 

utilize any method to keep the nozzle hook in the off position. 

6.6 Ensure that the ground strap is properly connected to an acceptable ground.

7. TEST PROCEDURES 

7.1 Prevent dispensing from all other fueling positions that share the same INCON 

ISD System Vapor Flow Meter being tested. 

7.2 Record the INCON ISD System Vapor Flow Meter serial number and fueling 

position being tested on a field data sheet. An example of a typical field data 

sheet is provided at the end of this exhibit. 

7.3 Completely drain any gasoline that may be in the nozzle and hose vapor 

return path by any acceptable method. 

7.4 Turn the ball valve to the open position and adjust the nitrogen flow using 

the rotometer to 60 cfh +/- 5.0 cfh. 

7.5 Once the nitrogen flow is set, turn the ball valve to the closed position to stop 

the flow of nitrogen through the gas volume meter. This will ensure the 

nitrogen flow rate is set and the nitrogen can instantaneously be activated 

when the ball valve is turned to the open position. 

7.6 Install the Balance Nozzle Adapter on the appropriate nozzle as shown in 

Figure 2. Apply appropriate amount of lubricant to the O-rings located inside 

the Balance Nozzle Adapter. Lubricant can also be applied to the nozzle 

spout and the face seal or boot face (rubber boot) of the nozzle and the back 

of the Balance Nozzle Adapter if necessary. 

7.7 Authorize the fueling point you are testing at the point of sale (POS) and select 

a fuel grade at the dispenser. Record the initial reference gas volume meter 

reading on the field data sheet. An example field data sheet is provided at the 

end of this exhibit. 

Note: Only one fueling point and grade per dispenser needs to be tested. 

7.8 Simultaneously squeeze the nozzle handle to the full dispensing position and 

turn the ball valve to the open position to allow nitrogen to flow. 

Note: If the nozzle handle is not engaging the vapor/product valves will not 

open within the nozzle, turn off the nitrogen flow using the ball valve; 

remove the Balance Nozzle Adapter from the nozzle to release the nitrogen 

pressure build up and repeat sections 7.8 and 7.9. Excess pressure build 

up in the nozzle will engage the secondary shut-off diaphragm and not 

allow the vapor/product valves within the nozzle to open. 
EMCO Phase II EVR System with Hirt Thermal Oxidizer Including INCON ISD 

Exhibit 10 – VR-208-A 

- 9 -

7.9 Simulate dispensing fuel for approximately 1 - 2 minutes. Simultaneously 

stop the flow of nitrogen by turning the ball valve to the closed position and 

also releasing the nozzle handle. Immediately (use any means to turn the 

hook signal off) hang up the nozzle in the dispenser (dispenser lever in the 

close position) to end the transaction at the POS. 

Note: Final volume values may be biased if the ball valve and the nozzle 

handle are not activated at the same time. If the ball valve is open 

before the nozzle vapor valve leakage will occur around the nozzle 

boot. If this happens you must Re-run the test. 

7.10 Record the end meter reading from the reference gas volume meter. 

Calculate the total cubic feet value by subtracting the initial meter reading 

obtained in section 7.7 from the final meter reading in this section. 

7.11 Convert the total cubic feet value to gallons using the equation on the field 

data sheet or section 9.1 of this procedure. Record the final vapor gallon 

value on the field data sheet. 

7.12 Wait two minutes after the fueling transaction has ended with the dispenser 

lever in the close position. 

7.13 To obtain the fueling transaction from the INCON ISD System, connect a Lap 

Top computer or equivalent to the INCON ISD System console using a Cat 5 

crossover cable. Open TSA Upgrade Tool Application file “TSA 

UpgradeTool.exe.” Type in the INCON IP address from the console and 

Query the ISD. Click on Tab “VRM”; Click on “Get Last”. The last transactions 

for all of the fueling points will be displayed. See Figure 3 below.

System Vapor Flow Meter and the reference gas volume meter is not within 

15%, then proceed to section 7.16. 

7.16 Conduct the leak test in section 6.4 to evaluate the test equipment. If the 

equipment leak test passes proceed to section 7.17. If the test fails, repair 

the leak and go back to section 7.7. 

7.17 Perform this test two more times and average the three readings together. 

If the vapor volume percent difference between the three recorded INCON 

ISD System Vapor Flow Meter and the three reference gas volume meter is 

within 15%, check “Pass” on the field data sheet. 

7.18 If the operability test fails, check the fueling point and make sure the 

reading from the dispenser is correct. Be sure that the fueling point 

opposite the nozzle is hung up (i.e. hook lever closed during the test). Each 

test run must start and end at the same POS. Only perform one transaction 

at a time and complete this transaction before starting another transaction.

Determining UST Pressure - The pressure of the Underground Storage Tank 

(UST) is determined at the Phase I vapor recovery adaptor (dry break assembly) 

with a vapor coupler test assembly as shown in Figures 2 and 3 of TP-201.3 

(Determination of 2 Inch WC Static Pressure Performance of Vapor Recovery 

Systems of Dispensing Facilities) or a modified dust cap test assembly as shown in 

Figures 1a and 1b of this exhibit. The test assembly is equipped with a center 

probe, which opens the dry break, and a quick connect fitting that is connected to 

an electronic pressure measuring device or digital manometer. The test assembly 

should open the dry break with minimal venting of the USTs. This test can be 

performed while product is being dispensed into motor vehicles. 

3. Biases and Interferences 

3.1 This test shall not be conducted within 30 minutes following gasoline 

transfer from a cargo tank. 

3.2 This test shall not be conducted if the processor is operating (the VCS-100 

vapor processor is running if the green indicator lamp on the Hirt indicator 

panel is lit). 

3.3 This test shall not be conducted if the system ullage pressure is less than 

negative eight (-8.0) inches WC or greater than positive eight (+8.0) inches 

WC. 

4. Range and Accuracy 

Digital Manometer (Electronic Pressure Measuring Device) 

Minimum readability shall be 0.01 inches WC with measurement range(s) to 

include at least up to positive and negative ten (±10) inches WC with a minimum 

accuracy of plus or minus 0.05 inches WC of full scale. 

5. Equipment 

5.1 The dust cap test assembly shall be modified in the following manner: 

5.1.1 Install a probe in the center of the dust cap as shown in Figure 1a

the manufacturer’s operating instructions shall be kept with the equipment. 

6. Digital Manometer Calibration Requirements 

6.1 A copy of the most current calibration of the digital manometer shall be kept 

with the equipment. 

6.2 All digital manometers shall be bench tested for accuracy using a reference 

gauge, incline manometer or National Institute of Standards and Technology 

(NIST) traceable standard at least once every twelve (12) consecutive 

months. Accuracy checks shall be performed at a minimum of five (5) 

points (e.g., 10, 25, 50, 75 and 90 percent of full scale) each for both 

positive and negative pressure readings. Accuracy shall meet the 

requirements of Section 3.2 of TP-201.3.

7. Pre-Test Procedure 

7.1 Turn on digital manometer and allow instrument to warm up for five minutes. 

7.2 Zero out digital manometer using adjustment pod on top of instrument in 

accordance with manufacturer’s instructions. Drift may be minimized by 

re-zeroing immediately after use by venting both pressure ports to 

atmosphere and adjusting the knob until the display reads exactly zero. 

7.3 Attach the male quick connect fitting to the female quick connect fitting on 

the modified vapor dust cap. 

7.4 Attach digital manometer to open end of Tygon tubing.

8.1 Access the INCON ISD System Vapor Pressure Sensor, which is located in 

the dispenser closest to the USTs. Record the Vapor Pressure Sensor 

location and serial number on the data forms 1 and 2. 

8.2 Turn the Vapor Pressure Sensor ball valve to the closed position. This 

isolates the Vapor Pressure Sensor from the UST ullage space (see Figure 

2). 

8.3 Remove the plug from the Vapor Pressure Sensor ball valve (see Figure 2). 

 

8.4 Verify on the VRM Status on the LCD of the console that the pressure value 

is zero inches WC, ±0.20 inches WC. 

If the vapor pressure sensor is within ±0.2 inches WC of zero, proceed to 

Section 8.5 of this exhibit. 

If the pressure value is not within ±0.2 inches WC of zero, the vapor 

pressure sensor will need to be calibrated. Proceed to section 8.4.1-8.4.3. 

8.4.1 On the LCD of the console, go to the VRM Control page, refer to 

Figure 3, and perform the following steps 

a. Press the CONTROL icon. This allows access to the control 

menu screen. 

b. Press the CALIBRATE ZERO OFFSET icon. 

c. Press anywhere in the upper calibration box. Select “Yes” to 

calibrate the sensor. This will zero the pressure reading for 

atmospheric pressure. 

8.4.2 Verify on the VRM Status page that the pressure value is now 

reading zero (0.0) inches WC, ±0.20 inches WC. 

8.4.3 If the pressure reading from the INCON VRM Console is NOT within 

±0.2 inches WC from zero, the Vapor Pressure Sensor is not in 

compliance with the pressure sensor requirements of Exhibit 2. 

Proceed to the INCON ISD System trouble shooting manual available 

on the Franklin Fueling Systems website.

8.5 Record the above information on Form 1 “Data Form for Vapor Pressure 

Sensor Ambient Reference Test.” Districts may require the use of an 

alternate form, provided it includes the same minimum parameters as 

identified in the Data Form. 

8.6 Reinstall the plug on the Vapor Pressure Sensor ball valve. Turn the ball 

valve handle to the “normal position” (See Figure 2).

9. Test Procedure for Testing the INCON ISD System Vapor Pressure Sensor at 

UST Pressure 

9.1 Attach the dust cap or vapor coupler test assembly to the vapor adaptor 

(Figure 1b). 

9.2 On the touch-screen display at the INCON VRM console, go to the 

VRM»Status page. 

9.3 Simultaneously record the ullage pressure from the digital manometer 

(connected to the vapor coupler test assembly) and the INCON VRM 

Console. Record the above information on Form 2 “Data Form for Vapor 

Pressure Sensor UST Pressure Test.” Districts may require the use of an 

alternate form, provided it includes the same minimum parameters as 

identified in the Data Form. 

9.4 Verify the vapor pressure sensor reading from the INCON VRM Console is 

within ±0.2 inches WC from the digital manometer reading. If difference is 

not within ±0.2 inches WC, the Vapor Pressure Sensor is not in 

compliance with the pressure sensor requirements of Exhibit 2. 

Proceed to the INCON ISD System trouble shooting manual available on 

the Franklin Fueling Systems website.
