Follow the quick start guide. It is included with your order and can also be found under each product and at the bottom of this page. Double-check that all values in menus 10–14 are correct. Also, watch the installation video under each product. It is also available at the bottom of this page.
Check the letter in the upper right corner of the display.
"R " indicates that the meter is set correctly in menus 10–14
"E" means there is no signal between the sensors. Verify the settings in menu 10-14
"D" indicates a weak signal between the sensors and that the meter is attempting to adjust the gain between the sensors. Move one of the sensors slightly
Start by checking the values you entered in menus 10–14 to make sure they are correct (plastic = PVC). Double-check the information in the quick start guide!
Sand the pipes if there is paint, rust, or buildup. Apply contact grease until it overflows. Do not tighten too much, or the grease will be squeezed out.
The sensors must be mounted in the middle of the pipe at the 9 o'clock or 3 o'clock positions, aligned with each other. For measurement method Z, the sensors must be mounted at the 3 o'clock and 9 o'clock positions
Correct sensor spacing according to menu 14 – try adjusting one sensor a few millimeters at a time
The distance is measured from inner edge to inner edge in mm
The label should face outward, and the cables should run outward from each other, right to left
Börja med V metoden upp till DN200-byt och till Z metoden om ej fungerar. Mätmetod Z kan vara lämplig att användas på rör < DN32 Finns det böjar/ventiler/pumpar, etc i närheten av givarna? Rekommenderat avstånd är 10xrördiameterna framför första givaren och 5Xrördiametern efter nedströmsgivaren Äldre pumpar kan skapa turbulent vatten, öka då avståndet till 30x uppströms och 10x nedströms
Move one of the sensors a few millimeters at a time along the tube until the ratio reads between 97% and 103%
Go to menu 04. The signal strength should be above 80 (UP, DN) and Q between 60 and 100. Go to “Sound,” where the value should be between 97% and 103%. If these values are correct, the meter is installed properly.
Menu 04 shows the correct Q value (between 60 and 100) and Ratio (should be between 97 and 103%), but no flow is shown in Menu 01
The likely cause is that the flow rate is less than 0.03 m/s.
Adjust the low flow cutoff in Menu 21 to a lower value.
The Z-method. It has a Sound value of 80 but a Q-value of 0 even when the transducers are moved. If there is too little liquid in the pipe, ultrasonic measurement is not possible. The liquid must cover the transducers. The Z-method is suitable for use in sprinkler applications.
If the tubes are not completely full, measurement errors will occur. Go to menu 26 and change the scaling factor. It is set to 1. If the tubes are 3/4 full, change it to 0.75.
Go to Menu 22. Make sure the tube is filled with liquid and that the liquid is at rest in the tube. Zero-flow calibration takes about 30 seconds to complete.
Settings in Menu 32
Testing the analog output in Menu 32 under the "Check" tab
The Modbus protocols are listed at the end of the manual. Modbus settings in Menu 30
The default communication settings are 9600 baud (can be changed), no parity (None, cannot be changed), 8 data bits, 1 stop bit, 1 start bit. Standard Modbus address 55 (can be changed)
See information on registers at the end of the manual
M-Bus is optional; please specify this when ordering
Different liquids and temperatures have different acoustic properties. Please refer to our documents (found under "Documents" for each product) for the acoustic properties of various liquids. Enter the sound speed for the selected liquid in Menu 12.
The flow meter is calibrated for water at 20 degrees
Check that the correct parameters are used in Menu 10-14
Check Menu 04, the "Sound" tab, to ensure that the ratio value is between 97-103%
Check that zero-flow calibration has been performed
Is the flow meter's sound velocity set to the correct fluid and temperature?
Note: All flow meters have some degree of inaccuracy, so it is difficult to get two meters to show exactly the same flow rate or energy consumption.
If the above checks are correct, the meter is installed properly. Proceed to check the permanently installed meters. Permanently installed meters may need to be calibrated after a few years.
