What problems are encountered when using split electromagnetic flow meters?

The split electromagnetic flowmeter is mainly used to measure the volume flow rate in conductive liquids and slurries in closed pipelines. Including highly corrosive liquids such as acids, alkalis, and salts. This product is widely used in petroleum, chemical, metallurgy, textile, food, pharmaceutical, paper and other industries as well as environmental protection, municipal management, water conservancy construction and other fields. 1. Power supply problem Since the split electromagnetic flowmeter requires an external power supply, it makes outdoor installation inconvenient and limits the use of the split electromagnetic flowmeter in suburban pipe networks. In addition, the split-type electromagnetic flowmeter does not have its own power supply. Once the power is cut off, the data of the flowmeter used as a settlement water meter will be lost. This raises new problems in the measurement and calculation of the missing water volume during the power outage period. General water supply Enterprises and users are handled on a case-by-case basis, which adds a lot of workload. If the split electromagnetic flowmeter can have its own power supply, this problem can be fundamentally solved and its application in settlement water meters will be promoted.

Nowadays, lithium batteries can be used for power supply, which solves this problem. 2. Lightning protection problem. Whether it is a settlement water meter or a split electromagnetic flowmeter for regional measurement, in relatively open suburbs, especially in Guangdong where thunderstorms cover a large area, The lightning protection of split electromagnetic flowmeter is a relatively severe test. After strict grounding and power protection, the probability of being struck by lightning for a split-type electromagnetic flowmeter installed in an open area is still very high. Therefore, a simple and effective way is to improve the lightning protection performance of the flow meter itself. If it cannot be fundamentally solved, its internal circuit should be separated and protected, so that even if it is damaged by lightning, the replacement cost can be reduced. 3. Signal transmission issues used in regional pipe networks The split electromagnetic flowmeter can provide certain decision-making information for urban water supply dispatching, so we hope that the electromagnetic flow signal whether used for user settlement or regional pipe network will be real-time and continuous. Current split-type electromagnetic flowmeters require water supply companies to develop or select other data transmission systems to achieve real-time monitoring of data. This not only increases the cost investment, but also increases the difficulty of operation and management. If the split electromagnetic flowmeter can complete the automatic conversion and wireless transmission of signals in the instrument itself, reducing the problems of compatibility or mutual conversion of data collection, it will provide convenience for the use of enterprises and will also promote the application of split electromagnetic flowmeters.
