Failure analysis and elimination method of ultrasonic flowmeter in use process
1. Does the ultrasonic flowmeter fluctuate instantaneously?
A, the signal intensity fluctuates greatly; B, the measurement fluid itself fluctuates greatly;
Solution: Adjust the position of the probe and increase the signal strength (maintained above 3%) to ensure the signal strength is stable. If the fluid fluctuates greatly, the installation position is not good. Select a new point to ensure the working conditions of 5D after the first 10D of the straight pipe section. .

2. The signal of the external clip ultrasonic flowmeter is low?
The pipe diameter is too large, the pipe scale is serious, or the installation method is wrong.
Solution: For large pipe diameter and serious fouling, it is recommended to use a plug-in probe or choose a "Z" type installation method.

3. The signal of the plug-in ultrasonic flowmeter probe decreases after a period of use?
The probe may be offset or the surface of the probe may be thick.
Solution: Re-adjust the position of the probe and clear the transmitting surface of the probe.

4. There is no display at startup to check whether the power supply property corresponds to the rating of the flowmeter and whether the fuse is blown. If the above problem does not exist, it is recommended to send the flowmeter back to our company for inspection by a professional technician.

5. The meter has only backlight after it is turned on, and no characters are displayed. This situation is generally the damage of the program chip. It is recommended to send the flowmeter back to our company for processing.

6. Ultrasonic flowmeter cannot be used under strong interference on site?
The power supply has a large fluctuation range, there are inverters or strong magnetic field interference around it, and the ground wire is incorrect.
Solution: Provide a stable power supply for the flowmeter. Install the flowmeter away from the inverter and strong magnetic field interference, and have a good grounding wire.
