use ultrasonic flowmeter note

1, outside clip flowmeter signal low? Too much pipe diameter, pipe scaling is serious, or choose to install right way. Solution: the diameter is too large, severe scaling, recommended plug-in probes, or select Z type installation. 2, the instantaneous flow meter volatility? A large, signal intensity fluctuation; B, itself measuring fluid volatility; Solution: adjust the probe position, increase the signal strength ( At more than 3%) Ensure stability in signal strength, such as fluid volatility itself, the location is not good, to study, to ensure that after the first 10 d 5 d condition requirements.

3, up to check if the power properties correspond to the instrument rating, whether to blow a fuse, such as commend not in the above problem, to suggest the instrument back to us by the professional and technical personnel to check. 4, insert the probe to use after a period of time signal to reduce? May probe offset or probe surface scale of thick. Solution: to adjust the probe position, erase the probe surface.

5 meter, ultrasonic flowmeter at the scene under strong interference can't use? Power supply range is larger, surrounded by frequency converter or strong magnetic field interference, ground wire is not correct. Solution: provides stable power supply for instrument, instrument installation from frequency converter and the strong magnetic field interference, has the good grounding line.

6, boot after ultrasonic flowmeter meter only backlit, without any characters display this generally for program chip, suggested that the instrument back to our company for processing.
