What are the common faults of ultrasonic flowmeters in use? Posted by : admin / Posted on : Aug 20, 2021

Ultrasonic flowmeter is a non-contact instrument, it can not only measure the flow of large pipe diameter medium, but also can be used to measure the medium that is not easy to contact and observe. Its measurement accuracy is very high, and it is almost free from the interference of various parameters of the measured medium. It can especially solve the flow measurement problems of strong corrosive, non-conductive, radioactive and flammable and explosive media that other instruments cannot.

1. There is no display or black screen when booting.
No display or black screen when booting, first check whether the power supply is normal and whether the line is supplying power. If the power supply is normal, check whether the voltage corresponds to the rated value of the meter and whether the fuse is blown. If the above problem does not exist, please call our company's professional and technical personnel for consultation.

2. The instrument only has backlight after power on, without any character display.
After turning on the instrument, there is only backlight and no other characters are displayed. In this case, it is generally sufficient to re-power on. If the problem cannot be solved after re-power on, please call our company's professional technicians for consultation.

3. The signal decreases after the plug-in ultrasonic flowmeter is used for a period of time.
The signal of the plug-in probe decreases after a period of use, which may cause the probe's launch angle to shift or the probe surface to become fouled. Please readjust the angle of the probe and clean the emitting surface of the probe.

4. The signal becomes weak after using the external clamp ultrasonic flowmeter for a period of time.
Because the pipeline runs for a long time, there may be too much scale inside that affects the signal transmission. In this case, the scale needs to be cleaned; there is a gap between the external clamp sensor and the pipeline. It is recommended to polish the outer wall of the pipeline and reinstall the external clamp. sensor.
