Executive summary for the EC (not part of this legislation)  
Fuel dispensers are placed on the market in the Czech Republic pursuant to Measuring Instruments 
Directive 2004/22/EC. Once they hav e been put into operation, they are subject to national metrology 
regulation – verification (by specified due dates). This notified legislation only concerns measuring 
instruments that have already been put into operation. It does not concern placing them on the market 
or putting them into operation (except for cases pursuant to Article 23 of the MID). It does not 
concern measuring instruments for cryogenic liquids, for LPG, for CNG, and for aqueous urea 
solution (AdBlue).  
Requirements imposed upon these me asuring instruments in operation are fully compatible with the 
MID and are based on OIML R 117, which is the harmonised standard for the MID.  
Some parameters listed here are properties of the measuring instrument when it is new; they are listed 
here only b ecause their preservation while in service is subject only to visual or other checks during 
verification.

3   Technical requirements  
Technical requirements are  based on the requirements of the Government Order on Measuring Instruments and 
on the requirements of Recommendation OIML R 117 -1 Dynamic measuring systems for liquids other than 
water. Part 1: Metrological and technical requirements3). 
During verificatio n, measuring instruments are subject to  the technical requirements that were applicable when 
they were  placed into circulation.  
3.1    Dispenser design  
A measuring system that comprises a dispenser must consist of least the following main parts:  
– a flow met er, 
– a counter,  
– an indicator,  
– a point of separation, usually the dispensing nozzle,  
– a hydraulic circuit,  
– a gas separator.  
For proper operation, the following may need to be connected to the measuring system:  
– a filter,  
– a pump,  
– a conversion apparatus.  
The mea suring system may be equipped with other auxiliary and supplementary devices required for proper 
dispenser operation.  Measure of a General Nature No. 0111 -OOP -C033 -13 
6 3.2    Dispenser design requirements  
Othe r auxiliary devices may be part  of the dispenser or measuring instrument counter or  they may be c onnected 
to the counter via an interface.  
The dispenser may have its own supply of the measured liquid or it may be intended for installation into a central 
supply system. If the dispenser has its own supply, a gas separator must be installed immediately i n front of the 
measuring instrument inlet.  
Dispensers must be equipped with a zeroing device for the volume counter and the aggregate volume counter.  
If they also contain a price counter, it must be possible to zero it.  
Price and volume counter zeroing dev ices must be arranged so that the zeroing of one automatically leads to the 
zeroing of the other counter.  
It must be impossible to zero the volume and price counter during dispensation.  
It must be impossible to start a new measurement if the counters are n ot zeroed.  
If the dispenser has its own supply of the measured liquid propelled by an electrical motor, it must be equipped 
with a device that after the electrical motor stops prevents any further dispensation of fuel until the volume 
counter has been zero ed. 
If only one nozzle can be used during dispensation and in order to finish the dispensing process, it must then be 
replaced into the dispenser, further dispensation must be blocked until the indicator has been zeroed.  
If two or more nozzles can be used simultaneously or alternately, and then the nozzles must be replaced, further 
dispensation must be blocked until the indicator has been zeroed.  
The above requirements do not apply if an auxiliary hand pump is used.  
If the measuring system is equipped with a printer, it must be connected to the volume counter zeroing device. 
This arrangement must allow the printed filling sheet to be checked by comparing it with the information on the 
counter. The indicated amount displayed on the indicator must not change d uring printing.  
Dispensers must be designed to allow interruptible activity.  
After a power outage, the electronic display must continue to display:  
– continuously for at least 15 minutes and automatically after the main power supply fails, or  
– in total at lea st 5 minutes in one or several phases controlled manually for one hour after the 
failure.  
 
The dispenser must be designed so that after a power outage of more than 15 s, it is not possible to continue an 
interrupted dispensation.  
3.3    Self-serve arrangem ent with dispensers  
Information provided by the dispenser must remain available to the parties involved in the sales transaction until 
it has been settled.  
If a self -serve arrangement serves for two or more dispensers, each of them must have an identificat ion number 
that is part of each piece of data that the self -serve dispenser provides. In a self -serve arrangement, data on the 
indication device of the dispenser, the printer and the memory device display must not be different.  
If data transmission between  the dispenser and the self -serve facility is in the form of impulses, all data provided 
by the self -serve facility must not exhibit any mutual differences for any measured value related to the same 
measurement. Data provided by the self -serve facility mus t not differ from any of the piece s of data from the 
dispenser by more than one scale division or by the greater of two scale divisions, if different.  
The self -serve arrangement’s printer must not reproduce data from the dispenser as the difference between  two 
printed values.  
The manner of payment and/or operating mode must not change prior to the end of the current measurement. The 
self-serve arrangement, including conditions clearly specifying operating methods, must be designed so that the 
customer has a ccess to at least one primary datum from the dispenser for the customer, at least until the end of 
the transaction, so that the customer can check the dispensed amount and price. If the self -serve arrangement Measure of a General Nature No. 0111 -OOP -C033 -13 
7 summarises dispensed volumes of liquid on an ongoing  basis for various registered customers, the value of the 
scale division used for these sums must not have an effect on the smallest measured quantity.  
3.4   Full service mode  
If the measured data is displayed only on the dispenser indicator, this ind icator must be labelled with information 
clearly visible to the customer to the effect that this dispenser may be made available only by the operator after 
the current sales transaction has been completed, and that in the case of a dispute the information on the indicator 
is considered to be correct.  
In full service mode, the transaction is settled prior to the customer leaving the dispensing location. The 
measurement operation ends at the moment the transaction has been settled.  
3.5    Protection from unau thorised manipulation  
The dispenser has the required number of places for official seals.  
The dispenser is designed so that the measuring instrument  or indicator cannot be tamp ered with in a way that 
could affect the accuracy of measurement without visible  damage to an official seal.  
4   Labelling  
4.1    Dispenser labelling  
Each dispenser must have at least the following information on a special label:  
– the manufacturer’s name or brand;  
– the dispenser type;  
– the serial number and year of manufacture;  
– minimum flow Qmin and maximum flow Qmax; 
– minimum (if needed) and maximum operating pressure;  
– smallest measured volume ( Vmin); 
– the name or type of measured liquid, or the range of relevant characteristics;  
– the minimum and maximum temperature of the measured liquid;  
– the minimum and maximum ambient temperature;  
– the mechanical and electromagnetic class of the ambient environment;  
– the nominal AC voltage value and the limit DC voltage value;  
– accuracy class;  
– the number of the type approval certificate, if one exists, or i ndication of conformance;  
– identification of the positions of individual dispensing locations.  
This label must be firmly affixed to the chassis of the dispenser in a visible location and sealed.  
All information on the label on the dispenser must be legible.  
4.2   Labelling of dispenser parts  
Each separate metrologically relevant part of a dispenser, such as the flow sensor, measurement converter, 
counter or gas separator must contain at least (for example on another label) the following information:  
– the seri al number;  
– the manufacturer’s name or brand;  
– the number of the type approval certificate, if one exists;  
– other relevant characteristics for the specific device type.  Measure of a General Nature No. 0111 -OOP -C033 -13 
8 All information on the label on the part must be indelible, irremovable and legible.  
4.3    Indicator labelling  
The indicator must contain the following information:  
– the unit “Litre” or the symbol “L”, “l” or “dm3” after the amount indication;  
– the unit of national currency (Kč) near the indication of price to be paid;  
– the unit, for example. “Kč/L”, “Kč/Litre” or “Kč/dm3” near the unit price indication;  
– information regarding the  minimum measured quantity.  
If the conversion function is active and the amount under basic conditions is displayed, the measurement result 
must be accompanied by this information, for example “volume at 15  °C”. 
4.4   Recordkeeping  
In the case of dispensers, records of specified measuring instruments must be kept pursuant t o § 18(a) of the 
Metrology Act in the form of record sheets. A record sheet is a document intended to record technical 
information on the dispenser that is not provided on the label, primarily the serial numbers of individual parts.  
Each subsystem replacem ent, repair, servicing or verification of the measuring instrument is recorded in this 
document, which is provided during dispenser verification.  
5   Measuring instrument type approval  
Dispensers are placed on the market and into operation with a conforman ce appraisal pursuant to the 
Government Order on Measuring Instruments, 2) and thus are not subject to type approval.  
6    Initial verification  
These measuring instruments are placed on the market and into operation with a conformance appraisal pursuant 
to the Government Order on Measuring Instruments.  
Initial verification applies only to measuring instruments that at the given time have a valid type 
approval certificate with the utilisation of transitory provisions pursuant to § 9 of the Government 
Order o n Measuring Instruments, and to verification of measuring instruments following repairs.  
The procedure used during initial verification is the same as for subsequent verification pursuant to 
Chapter 7.  
7   Subsequent verification  
7.1   In general  
During s ubsequent verification, i.e. each verification of the measuring instrument performed after a prior 
verification and during verification pursuant to § 11(4) of the Metrology Act, the following activities and tests 
are performed:  
a) a visual inspection,  
b) an accu racy test,  
c) a test of auxiliary and supplementary devices.  
For dispensers with several independent dispensing locations (multiproduct dispensers), all dispensing locations 
are tested separately, and these tests are evaluated individually. Dispensers with tw o ranges are first verified for 
the lower range and then the test is extended by a test of the highest achievable flow rate.  
In the case of two flow sensors being installed in parallel, both flow sensors are first tested separately, and then a 
test of the entire system is performed (parallel connection) at all three stipulated flow rates.  Measure of a General Nature No. 0111 -OOP -C033 -13 
9 Dispensers with one hydraulic measuring part and several dispensing  (satellite)  locations  will be tested according 
to a regular test ing programme, and at the end a test at  the maximum achievable flow rate will be performed 
from each other dispensing location (from each satellite dispensing nozzle).  
Dispensers are tested with the liquid they are intended to measure. In the case of dispensers that are intended to 
measure seve ral liquids with various properties, for example for diesel fuel and petrol, verification applies only 
for that liquid for which a verification was performed in the installation location, unless otherwise stated in the 
type approval certificate or in the conformance appraisal documentation.  
7.2   Test equipment  
Test equipment used to perform accuracy tests must have an extended uncertainty of measurement less than 1/5 
of the maximum permitted error pursuant to Article 2.3.2.1.  
7.3   Visual inspection  
The fo llowing are assessed during a visual inspection of a dispenser:  
– whether the measuring instrument submitted for verification and its parts conform to the 
approved type or with the design of a measuring instrument for which conformity has been 
declared durin g market introduction, and attention must be paid to checking labelling pursuant 
to Chapter 4;  
– whether the measuring instrument  and its parts, including rubber hoses, are physically 
damaged or that metal parts show signs of corrosion.  
If the measuring inst rument does not meet the visual inspection requirements, no further tests need be  performed.  
7.4    Dispenser accuracy test  
An accuracy test of a dispenser and its measuring instruments is performed using the volume method, by 
dispensing a specified amount  of liquid into a reference graduated container at a specified flow rate.  
Test flow rates are specified according to the following relationships:  
– Q1 = (1 to 1.1) × Qmin, 
– Q2 = (0.22 to 0.28) × Qmax, 
– Q3 = (0.6 to 1) × Qmax. 
At each of the three test flow rat es, measurement errors for the tested dispenser are calculated. The test is 
repeated at least twice for each flow rate.  
The amount of liquid used during the accuracy test must be at least:  
– the amount dispensed at the test flow rate in 60 s, or  
– 2 000 × the scale division of the indicator.  
The dispenser has passed the accuracy test if none of the relative deviations of the indicated volume exceed the 
maximum permitted error listed in Article 2.3.2.  
If all true measurement errors have the same sign, in order t o meet requirements of Article 2.3.2.6, at least one of 
the measurement errors at a typical flow rate between 0.25 Qmax and Qmax must be less than half the maximum 
permitted error.  
7.5   Tests of auxiliary and supplementary devices  
Correct functioning of au xiliary and supplementary devices is checked, if the dispenser is equipped with them. 
The relevant test is performed only once. Tests of auxiliary and supplementary devices may be combined with 
the accuracy test. The following tests are performed if they a re relevant to the dispenser and the device is used 
for obligation relationships.  
7.5.1    Zeroing test  
The volume counter values and , if applicable , the price values are read after the dispenser has been zeroed.  Measure of a General Nature No. 0111 -OOP -C033 -13 
10 The residual indicated value after zeroing m ust not be greater than half the minimum specified volume deviation 
Emin for counters with continuous display.  
Counters with discrete display must indicate zero after being zeroed, without any ambiguity.  
7.5.2     Aggregate counter test  
The difference betwe en the figure on the aggregate counter and the figure on the indication device that apply to 
the same measurement is specified. The figure on the aggregate counter is specified at the difference between its 
initial and final state.  
The difference between t hese figures must not be more than one increment of the aggregate counter.  
7.5.3    Price counter test  
For dispensers with a mechanical counter, the test must be performed for at least two unit prices at maximum 
and minimum counter rotation rates.  
For dispe nsers with an electronic counter, the test is performed for a maximum unit price. The price indicated is 
compared to the price calculated as the product of the indicated volume and the unit price.  
During dispenser verification, the test is performed only f or the unit price currently in use.  
The deviation of the indicated price must not be greater than the price corresponding to Emin, or the smallest unit 
of currency.  
7.5.4     Auxiliary volume counter test  
Figures indicated by auxiliary volume counters are c ompared with figures on the indicator, applying to the same 
measurement.  
The figures must not differ from each other by more than one division of the scale that is the largest of the 
divisions of scales of devices being compared.  
7.5.5    Pre-set test  
Measu rement is performed using a volume or pre -set price , and the difference between the pre -set amount and 
the amount indicated by the volume or price counter at the end of the measurement is determined.  
For measuring instruments in prepaid or pre -ordered mod e, this difference must not exceed the minimum 
specified volume deviation Emin or the price corresponding to this deviation.  
7.5.6     Self-service facility test  
A measured quantity is taken using the self -service facility and the difference between the pre -set amount and 
the amount indicated by the volume or price counter at the end of the measurement is determined.  
The results must not differ from each other. For measuring instruments in prepaid or pre -ordered mode, pre -set 
requirements also apply to the s elf-service facility.  
7.5.7    Printer test  
Figures from the printer are compared with figures on the indicator that apply to the same measurement.  
These figures must not differ from each other by more than one division of the indicator.  
7.5.8     Attached t hermometer test  
During the test, the deviation of the attached thermometer at three temperatures is determined: Tmin, 15 °C and 
Tmax. 
The difference between the temperature figure Ti indicated on the dispenser and the figure Tn indicated by the 
temperature  reference is determined in  °C.  
During a test of the thermometer as a whole, which is composed of a temperature sensor and an electronic 
transducer, the ascertained deviations of the attached thermometer must not exceed the value of the maximum 
permitted error ±0.5  °C. Measure of a General Nature No. 0111 -OOP -C033 -13 
11 During a test of the thermometer where the temperature sensor and the electronic transducer are tested separately, 
the ascertained deviations of the temperature sensor must not exceed the value of the maximum permitted error 
±0.4 °C, and the  ascertained deviations of the electronic transducer must not exceed the value of the maximum 
permitted error ±0.3  °C. 
7.5.9    Conversion apparatus test  
During this test, the accuracy of the conversion apparatus is tested at three temperatures of the test liquid: Tmin, 
15 °C and Tmax. During the conversion apparatus test, the test liquid temperature may be simulated using signals 
(e.g. electric resistance) or the appropriate measurement may also be simulated using primary signals (e.g. 
electronic impulses).  
The ascertained relative deviation of indicated volume Ebv at a base temperature Tb = 15 °C must not exceed the 
value of the maximum permitted error ±0.5  °C. 
If the measured volume Vn is simulated using measurement signals, the relative deviation Ebv in indicated volume at the 
base temperature must not exceed the maximum permitted error of the conversion apparatus ±0,2  %. 
7.6    Setting automatic temperature compensation  
If the dispenser is equipped with automatic temperature compensation (ATC) and has a l abel indicating 
“Tb = 15 °C”, then the ATC function must be switched on, tested during verification, and this position secured 
with an official seal. This requirement also applies to dispensers that have had the ATC function installed after 
being put into operation.  
If a dispenser equipped with ATC is put into operation or verified at a specific petrol station with the ATC 
function switched on, and is to be verified with the ATC function switched off, the “ Tb = 15 °C” label must be 
removed; simply pasting o ver the label is not considered removal. Such a dispenser with an ATC function that at 
the given petrol  station  has already been in use or verified with the ATC function switched off, can no longer be 
verified with the ATC function switched off (with the “ Tb = 15 °C” replaced).  
If the dispenser is equipped with ATC, but at the relevant petrol station has not been put into operation, used or 
verified with this function switched on, the “ Tb = 15 °C” label must not be placed on the display, the ATC 
function mu st be switched off (is not tested during verification) and secured in this position with an official seal.
