1. First make sure that the pipe is full of fluid.
2. If the pipe is too close to the wall, install the probe on a pipe with a skewed angle, and instead of installing it on a horizontal pipe diameter, use the Z method to install the probe.
3. Carefully select the dense part of the pipe and polish it thoroughly, apply a sufficient amount of chelating agent to install the probe;
4. Carefully and carefully move each probe near the mounting point to find the maximum signal point to prevent the ultrasonic beam from reflecting the expected area due to fouling of the inner wall of the pipe or due to local deformation of the pipe and miss the possibility of receiving a stronger signal. Installation point
5. The metal pipe with serious fouling of the inner wall can be used to make the scaling part fall off or crack, but it should be noted that sometimes this method will not help the transmission of ultrasonic wave because of the gap between the scaling and the inner wall.
Do you understand this problem now? Simple. These problems should be solved when they are selected and installed again.
What is the reason why electromagnetic flowmeters cannot receive signals or are too weak?
If the electromagnetic flowmeter receives no signal or is too weak, what is the reason? The article is provided by Jiangsu Jinhu Co., Ltd., thanks to the instrument exhibition network to support the electromagnetic flowmeter can normally run for a long time without any maintenance after installation. , Then need maintenance and daily inspection. No signal is received or the signal is too weak is a minor problem. Therefore, it does not surprise you that you can solve the problem with the following steps.
