What about weak signal of measuring and controlling instrument?

Generally, the measuring and controlling instrument does not need to be maintained and maintained after it has been installed. However, after a period of time need to be regularly maintained and maintained, testing found that the signal or signal is not received too weak and so on, and conscientiously do the following steps can be solved.

1. first, make sure the pipe is filled with fluid.

2. if the pipe is too close to the wall, the probe can be mounted on the pipe diameter with an inclined angle, instead of being installed 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 polish it thoroughly. Apply sufficient lotus root mixture and install the probe;

4. were carefully in the slowly moving near the installation point of each probe, find the maximum signal, because the pipe wall to prevent node scale or because local pipeline deformation due to ultrasonic beam reflection area and is expected to miss the received signal strong mounting point;

5. instrument for metal pipe wall scaling serious can be used to hit the scaling part off or crack, but note that this method sometimes because the transmission between the scale and the inner wall of the void and not for ultrasonic.
