Electromagnetic flowmeters measure the advantages of chilled water: for example: no pressure loss, high accuracy, and good stability. However, due to the characteristics of chilled water, some problems should be paid attention to in the use of electromagnetic flowmeters.
Electromagnetic flowmeter problems in the village, pay attention to the problem of negative pressure on the memory. When measuring the media has a certain degree of corrosivity, we must use PTFE memory materials. However, electromagnetic flowmeters using PTFE materials cannot withstand negative pressure electromagnetic flowmeters. There are two ways to solve the problem:
First, the original vent valve was changed to a one-way valve (non-return valve). When there was a slight negative pressure in the pipe, the non-return valve automatically opened and sucked air from the atmosphere, thus ensuring safety.
Second, the use of memory with a skeleton, the disadvantage is to increase investment costs.
