Electromagnetic flowmeter signal is too weak how to solve
The titanium plate heat exchanger is safe and reliable to use: two sealing devices are designed between the plates, and a signal hole is provided, once a leak occurs, it may be external, that is, to prevent the mixing of the two media to play a safety alarm.
Small cooling water: titanium plate heat exchanger due to the geometry of its flow path, and the two liquids are very high thermal efficiency, so the cooling water consumption can be greatly reduced. This in turn reduces the installation costs of pipes, valves and pumps.
Finned titanium tube heat exchangers are also known as tube fin heat exchangers. Its structural characteristics are equipped with many fins on the outer surface or inner surface of the heat exchanger tube. Common fins are longitudinal and transverse. Titanium fin row tube heat exchanger is used as a condensing unit, which is widely used in industry. Using gas instead of water-cooled heat dissipation can not only be applied from areas with little water, but also in areas with abundant water resources, the choice of air cooling has also achieved great economic benefits.

Electromagnetic flowmeters generally operate for a long period of time without maintenance after installation, and require maintenance and routine inspections afterwards. It is normal to receive no signal or the signal is too weak. How to solve it?
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 the pipe diameter with an inclination angle, instead of installing it on the diameter of the horizontal pipe, use the Z method to install the probe. 3. Carefully select the dense part of the pipe and fully polish the light, apply fully The chelating agent is installed with 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 pipeline or due to local deformation of the pipeline. Installation point
5. The metal pipe with serious fouling on the inner surface of the electromagnetic flowmeter can be used to make the scaling part fall off or crack. However, it should be noted that this method sometimes does not help the ultrasonic waves because of the gap between the scaling and the inner wall. Transmission.
