Problems solved by technology

The current water flow monitoring meters all use traditional flow meters or flow water meters, but there is a defect in the existing flow meters or flow water meters. When the flow in the pipeline fluctuates greatly, it is limited to the existing flow meter impeller structure. As a result, the flow cannot be accurately monitored, making the measurement results inaccurate

At present, in order to solve this problem, a bypass branch is installed on the pipeline, a large flow meter and an electric control valve are installed on the main pipe, and a small flow meter and an electric control valve are installed on the bypass branch, and then flow meters of different sizes are used to cooperate. The solenoid valve controls the electric control valve to open the main pipe or the bypass branch pipe according to the flow rate to realize accurate flow monitoring. This method not only complicates the pipeline setting, but also has high cost. At the same time, due to the increase of electronic control equipment parts, the circuit stability is poor and the monitoring results are also poor. Unstable and prone to failure
