This anti dry-running sensor reduces the risk of dry-running by up to 50%. If the LiqTec senses no liquid in the pump, it stops the pump at once. But, the CR LiqTec is much more than an anti dry-running device.

The sensor also prevents excessive liquid temperatures above 130°C from damaging the pump. In addition, the CR LiqTec can also be connected to the thermistor or PTC on the motor. If the motor temperature exceeds a certain level, the sensor will stop the pump immediately.
