How to solve the problem that the electromagnetic flowmeter signal is too weak - focus on microfluidic control

Electromagnetic flowmeters generally operate normally for a long period of time without maintenance after installation, and then require maintenance and daily inspection. It is a small problem to receive no signal or the signal is too weak. So there is no need to be surprised, and the following steps can be taken seriously.

1. First confirm whether the pipeline is filled with fluid

2. If the pipe is too close to the wall, the probe can be installed on the diameter of the pipe with an inclined angle, and it is not necessary to install it on the horizontal pipe diameter. The Z method should be used to install the probe.

3, carefully select the dense part of the pipe and fully polish the light, apply a sufficient chelating product to install the probe;

4. Carefully move each probe slowly around the mounting point to find the maximum signal point to prevent missed reception of strong signals due to fouling of the inner wall of the pipe or due to local deformation of the pipe causing the ultrasonic beam to reflect the expected area. Mounting point

5. The metal pipe with serious scaling on the inner wall of the electromagnetic flowmeter can be used to strike off or crack the scale. However, it should be noted that this method sometimes does not help the ultrasonic wave because of the gap between the scale and the inner wall. Transmission.
