Ultrasonic flowmeter in use pay attention to the following:
1, transient flow meter wave big?
A, large variation signal strength; B, itself measure the fluid fluctuation;
Solution: adjust good probe position, improve the signal strength (to stay above 3%) ensure that signal strength stability, such as itself large variation fluid, the position is bad, to study, make sure that the 10 D 5 D after the operation condition of the requirements.

2, the clip flowmeter signal low?
Pipe diameter is too large, pipe scale and serious, or choose to install way wrong.
Solution: too big for pipe diameter, scale serious, suggested the plug-in probe, or choose "Z" type of installation.

3, plug-in probe after a period of using signal down?
May occur migration or probe probe surface scale thick.
Solution: to adjust the probe position, clear washing probe launch face.

4, boot no display
Check whether the power of the rated capacity of the instrument and attribute corresponds, fuse is burned off, if the above problems are not hired in, suggested that the instrument to back by our professional and technical personnel inspection.

5, after startup instrument only backlighting, without any character display
This situation general for the program to chip loss, suggested that the instrument back our company for processing.

6, instrument in the strong interference can't use?
The power supply fluctuation range is very large, strong magnetic field around the inverter or interference, ground is not correct.
Solution: to provide stable power supply power meter, instrument installation of the transducer and away from the strong magnetic field interference, and a good grounding
