Automatic switch for the pump controller prevents wastage of water and electricity. There has less probability of damaging your pump, through an automatic on-off system. The automatic devices can be programmed to pump the water once the time is set. So it requires no human intervention which is why it is in great demand. The level control devices also include sensors that are specially designed to monitor the water level in the tanks.

Automatically stops the water pump from running dry and overheating when the water supply is running out. Makes your plumbing or irrigation system more efficient, meaning you'll save water and possibly electricity as well.A pressure switch is an electromechanical sensor that detects a pump's pressure settings. When the pressure goes above a certain threshold, it will signal the pump to shut off. When pressure dips below that set point, the motor will turn back on.
