Giving a user defined name to the measured volume flow rate

The name is used to identify the process value in the user defined views and in all the menus where theprocess value is displayed.

14.4.2

Activating the damping of the volume flow rate values andselecting a predefined damping level

The damping makes it possible to damp the fluctuations of the measured values of the volume flow rate:• on the totalizers,• on the outputs. The damping set for an analog output comes in addition to the damping of the volume
flow.*)• on the liquid velocity value. The damping of the volume flow comes in addition to the damping set for theliquid velocity.
The damping is not applied to the new measured value, if the 2 following conditions are met:
• a Low, Medium or High damping level is active,• and the variation between 2 values that are measured one after the other is higher than 30 % (for example
when charging the pipe or stopping the flow).
By default, the measured volume flow rate values are damped with the level Medium.
The low damping level or no damping at all (None) are suited for applications/processes that need fast
response times.
The medium damping level or the high damping level are suited if the volume flow rate values change
slowly.
→ As an alternative to the 3 predefined damping levels Low, Medium or High, you can set your own
damping parameters. See chapter 14.4.3.

Setting the parameters of the differentiation factor(optional feature)

14.11.1

What is the differentiation factor?

The differentiation factor (DF) is a dimensionless measurement value which can be used to identify the liquid
flowing through the pipe.
Before SW version 05.00.00, differentiation factor was named density factor. Given the fact that the option
density appeared, the name was changed in order to avoid confusion.
The DF is a non-calibrated acoustic measurement based on the measurement of the speed of sound in theliquid and can be compensated by temperature. The DF gives an idea of the the density of most of aqueous
liquids. By default, the temperature compensation is related to water.
→ To set a temperature compensation, refer to chapter 14.11.10.
Air bubbles in the liquid have an unwanted effect on the DF accuracy.
The device measures DF in the range of 0.8...1.3:• If a liquid flowing through the pipe has a higher density than water, the measured DF is higher than 1.
• If a liquid flowing through the pipe has a lower density than water, the measured DF is lower than 1.
Examples of DF ranges:• The DF of water is in the range of 0.95...1.05.
• The DF of tomato ketchup is in the range of 1.1...1.3.

14.11.2

Activating the damping of the differentiation factor values andselecting a predefined damping level

The damping makes it possible to damp the fluctuations of the measured values of the DF:• On the totalizers• On the outputs. The damping set for an analog output comes in addition to the damping of the DF. *)The damping is not applied to the new measured value, if the 2 following conditions are met:
• a Low, Medium or High damping level is active• and the variation between 2 values that are measured one after the other is higher than 30 % (for example
when changing the liquid in the pipe)
By default, the DF values are not damped.
The Low damping level or no damping at all (None) are suited for applications or processes that need fast
response times.
The Medium damping level or the High damping level are suited if the DF values change slowly.
→ As an alternative to the 3 predefined damping levels Low, Medium or High, you can set your own
damping parameters. See 14.11.4*) Only variant with outputs.

Setting the parameters of the acoustic transmission
factor (optional feature)

14.12.1

What is the acoustic transmission factor?

The acoustic transmission factor makes it possible to know the quality of the transmission of sound in theliquid thus the reliability of the measurements.
Indeed, the wave transit time in the liquid and the wave amplitude change depending on the following
criteria:• the type of liquid: aqueous solution, oil solution, emulsion, etc.
• the presence of gas bubbles• the presence of solid particles• the liquid temperature• the DN of the pipe
The acoustic transmission factor, given in %, is calculated on the base of the amplitude changes of the
waves. The acoustic transmission factor of water without gas bubbles is equal to 100 % at a water temperature of +23 °C.
The temperature changes of the liquid are not compensated for the measurement of the acoustic transmission factor.
The device measures acoustic transmission factors from 10 % and up.
• If the wave amplitude in a liquid flowing through the pipe is higher than the wave amplitude in water, themeasured acoustic transmission factor will be higher than 100 %.
• If the wave amplitude in a liquid flowing through the pipe is lower than the wave amplitude in water, themeasured acoustic transmission factor will be lower than 100 %.
Gas bubbles or solid particles in the liquid have a similar effect on the transmission acoustic factor. If
the concentration of gas bubbles or solid particles increases in a liquid, the acoustic transmission factor
decreases. So, measuring and monitoring the acoustic transmission factor can be used to detect thepresence of gas bubbles or solid particles in the liquid.
→ Take into account that special process conditions can have an effect on aging of the sensor thus on the
acoustic transmission factor value.

14.12.3 Activating the damping of the acoustic transmission factor
and selecting a predefined damping level
The damping makes it possible to damp the fluctuations of the measured values of the acoustic transmission factor:• On the totalizers• On the outputs. The damping set for an analog output comes in addition to the damping of the acoustic
transmission factor *)The damping is not applied to the new measured value, if the 2 following conditions are met:
• a Low, Medium or High damping level is active• and the variation between 2 values that are measured one after the other is higher than 30 % *)By default, the acoustic transmission factor are not damped.
The Low damping level or no damping at all (None) are suited for applications or processes that need fast
response times.
The Medium damping level or the High damping level are suited if the acoustic transmission factor change
slowly.
→ As an alternative to the 3 predefined damping levels Low, Medium or High, you can set your own
damping parameters. See chapter 14.12.4*) Only variant with outputs.

The damping makes it possible to damp the fluctuations of the measured values of the acoustic transmission factor:• On the totalizers• On the outputs. The damping of the acoustic transmission factor comes in addition to the damping set foreach analog output *)By default, the measured acoustic transmission factor values are not damped.
To damp the fluctuations of the measured values, you can:→ Either select 1 of the 3 predefined damping levels: Low, Medium or High. See chapter 14.12.3.
→ Or you can set your own damping parameters with the Special damping.
With the Special damping, you can set 2 parameters:• a user-defined Response time in seconds,• the Jump threshold, i.e. a user-defined percentage. If 2 consecutive measured values vary for ± the percentage, no damping is applied to the second measured value.
To set your own damping parameters of the measured acoustic transmission factor, do the following:→ Select the device in the navigation area.
→ SAW sensor→ Parameter→ Add. meas. values→ Acoustic transmission factor→ Damping

The refresh time is the minimum time needed to update a measurement value. The refresh time has noeffect on the damping of the measured values.
The refresh time of the temperature values is a constant but the refresh time of the other measurement
values can be adapted to the process:• A very short refresh time is needed if the process requires quick volume flow rate measurement updates,for example for very short dosings.
• A long refresh time is sufficient if for example there are slow flow rate changes in the process.

You can check the correct operation of the sensor by comparing the current measured values of someparameters with their reference values. The reference values depend on the conditions of your process:• If you measure water at 23 °C ±5 °C (73.4 °F ±9 °F) that is free of gas bubbles and free of solids, thenthe conditions of your process are similar to the calibration conditions of the device at the manufacturer.
The reference values are those after the device calibration and they can be read in the menu Device
verification.
• If you do not measure water at 23 °C ±5 °C (73.4 °F ±9 °F) or the liquid is not water, then the reference
values are in the PDF file that you have generated with the Bürkert Communicator at the following times:- After the first commissioning of the device. Refer to chapter 10 Commissioning- After the last maintenance operation
To check the correct operation of the sensor, do the following:
Open the menu Device verification:→ Select the device in the navigation area.
→ SAW sensor→ Maintenance→ Device verification
The values of the parameters are displayed.
→ Calculate the deviation for each parameter that is listed in Table 23 or in Table 24. Use the following
formula:| current measured value – reference value |= deviationreference value- If you measure water at 23 °C ±5 °C (73.4 °F ±9 °F) that is free of gas bubbles and free of solids, thenuse the values that are displayed in the parameters from columns A and B of Table 23.

Configuring a digital output as a pulse output

When the digital output is configured as a pulse output, it transmits:• either a number of pulses proportional to the measured volume (pulse/volume),• or 1 pulse each time a set volume of liquid has been measured by the device (volume/pulse).
• or a number of pulses proportional to the measured mass (pulse/mass),• or 1 pulse each time a set mass of liquid has been measured by the device (mass/pulse).
The number of pulses that can be given out by a pulse output of the device is max. 2000 per
second.
By default, the value of the parameter pulse/volume is set for the full scale of the flow-rate measurement range. Observe the following rules to adapt the value of the parameter pulse/volume toyour flow-rate measurement range:• Make sure that the maximum flow rate value (in litres per second) multiplied by the pulse per litre
value is lower than 2000 pulses per second. Pulses above the 2000 pulses/s limit are not transmitted immediately but are accumulated. The accumulated pulses are transmitted as a block whenthe 2000 pulses/s limit is no longer exceeded.
• The pulse output of the device is connected to an input of another equipment, for example a PLC.
Take into account the frequency of the input, because it can be lower than the maximum pulse
frequency that you have set.
Calculation example for the number of pulses per volume:
Consider a device with DN40 ISO process connections. The following device data are needed:• Maximum measurable flow-rate at a liquid velocity of 10 m/s: 925 L/min→ Read the maximum flow-rate value in Outputs
