This product is an intelligent water pump controller with the following features: 1. Using high-precision impact-resistant liquid level sensor (transmitter), completely eliminating the stainless steel probe, float, photoelectric pressure gauge easy to damage, difficult to debug, unstable shortcomings, can real-time display the liquid level height, and can be adjusted in the panel or remote any working liquid level height. 2. Manual and automatic operation with phase error, three-phase unbalance, lack of phase, blocking, overcurrent, dry running, overvoltage, undervoltage protection; 3. By connecting with the remote control panel equipped with it, the voltage, current, liquid level height and other working conditions can be displayed remotely in real time, and all control functions can be realized.
