Insertion electromagnetic flowmeter is equipped with a pressure-opening and pressure-mounting technology. It can be installed without cutting off the water supply. It can also be installed on cast iron pipes, cement pipes, and integrated installation of flow, pressure and remote transmission,simple installation,waterproof IP68, strong anti-interference ability, can provide pressure measurement and two-way high-precision flow measurement, reliable measurement, can detect the real flow mutation of the pipethe ideal flow meter for leak detection. At the same time, with GPRS remote meter reading system, a time monitoring system integrating flow and pressure measurement, data acquisition, transmission and remote control is formed, so that it can be managed through system area management,analysis combined with the flow, pressure of monitoring point and other information. Dynamic control of leakage in the pipe network area, timely normal management, can greatly reduce the leakage rate. It can help factories and water departments to strengthen the management of the users, effectively reduce leakage rate, reduce non-revenue water, improve work efficiency, and achieve profitability.
