Ultrasonic flowmeter fault analysis: 1, boot no display check whether the power attributes and meter rating corresponding, fuse is burned, such as the above problems are not recommended, it is recommended to send the instrument back to our professional and technical personnel to check. 2, after starting the instrument only backlight, no characters show this situation is generally lost program chip, it is recommended to send the instrument back to our company for processing. 3, ultrasonic flowmeter can not be used in the field of strong interference? The fluctuation range of the power supply is large, there is a frequency converter or strong magnetic field interference around, and the ground line is incorrect. Solution: To provide a stable power supply to the instrument, the instrument installation away from the frequency converter and strong magnetic field interference, there is a good grounding line 4, instantaneous flow meter fluctuation? A. The signal strength fluctuates greatly; B, the measurement fluid fluctuation; Solution: Adjust the probe position, improve the signal strength (keep above 3%) to ensure that the signal strength is stable, such as the fluid fluctuation, the position is not good, re-select the point to ensure the first 10D after 5D working conditions. 5, ultrasonic flow meter signal is low? The pipe diameter is too large, the pipe scale is serious, or the installation method is not correct. Solution: For the pipe diameter is too large, serious scaling, it is recommended to use the insert probe, or choose “Z” type installation. 6, HD-CR plug-in ultrasonic flowmeter probe after a period of time to reduce the signal? The probe may be deflected or the probe surface may be thick with scale. Solution: readjust the probe position and clear the probe emission surface.
