[0002] At present, with the development of society, the demand for water consumption in all walks of life and among residents is increasing, which has increased the workload of water meter measurement. Traditional mechanical water meters can no longer meet the requirements of water consumption measurement in today's society. An electromagnetic water meter is a flowmeter that measures flow according to Faraday's law of electromagnetic induction. Electromagnetic water meters have the advantages of high measurement accuracy, zero pressure loss, no wear, a very large range ratio, stable operation, and long service life, and are widely used in various water measurement occasions.

[0003] Electromagnetic water meters are generally installed outdoors and are basically powered by a lithium battery pack. Since electromagnetic water meters consume a large amount of power, the battery needs to be replaced after the battery power is exhausted. The workload of replacing the lithium battery is very large, and the lithium battery and the circuit board are arranged in one cavity. When replacing the lithium battery, the circuit board and the communication module need to be disassembled for replacement. This not only increases the replacement difficulty but also easily causes the electromagnetic water meter to malfunction and cannot work properly during the replacement process.
