Ultrasonic flowmeter signal is weak will not deal with?
Ultrasonic flowmeter is a non-contact instrument, so it has the advantages of simple installation and maintenance, and is very popular with customers. However, because of this advantage of ultrasonic flowmeters, it is precisely after a period of use that the signal will be weak.
Today, flowmeter manufacturer Aister instrument provides several small solutions for this situation, and you can collect them if you need them.
1, first confirm whether the flow meter in the pipeline is full of fluid;
2, if the pipe is too close to the wall, the probe can be installed on the diameter of the pipe with a tilt Angle, rather than on the horizontal pipe diameter, the Z method should be used to install the probe;
3, carefully select the dense part of the pipeline and fully polish bright, apply sufficient lotus mixture to install the probe;
4. Carefully move each probe slowly near the installation point to find a larger signal point to prevent the installation point that can receive a stronger signal from being missed due to scaling on the inner wall of the pipeline or due to local deformation of the pipeline that causes the ultrasonic beam to reflect the expected area;
5, the inner wall of the metal pipe serious scaling can be used to make the scaling part fall off or crack, but it should be noted that this method sometimes because of the gap between the scaling and the inner wall and does not help the transmission of ultrasonic.
