1. The instantaneous flowmeter fluctuates greatly?
A. The signal intensity fluctuates greatly; B. The measured fluid fluctuates by itself;
Solution: Adjust the position of the probe to improve the signal strength (maintained at 3% or more) to ensure that the signal strength is stable. If the fluid fluctuation is large, the position is not good. Re-select the point to ensure the 5D working condition after the first 10D.
2. What is the signal of the clamp type flowmeter?
The pipe diameter is too large, the pipeline is heavily fouled, or the installation method is incorrect.
Solution: For large pipe diameters and serious fouling, it is recommended to use a plug-in probe or choose a “Z” type mounting method.
3, plug-in probe after a period of time to reduce the signal?
The probe may be deflected or the probe surface may be thick.
Solution: Readjust the position of the probe and clear the probe's emission surface.
4, boot no display
Check whether the power supply attribute corresponds with the rated value of the instrument and whether the fuse is blown. If the above problem is not recommended, send the instrument back to our company for inspection by professional technicians.
5, the instrument only backlight after boot, without any character display
This situation is generally a program chip loss. It is recommended that the instrument be sent back to our company for processing.
6, the instrument can not be used under the strong interference scene?
The power supply has a large fluctuation range, there is a frequency converter or a strong magnetic field around it, and the ground wire is incorrect.
Solution: Provide the instrument with a stable power supply, the instrument is installed away from the inverter and strong magnetic field interference, there is a good grounding line.
