Filling level controller, drain switch well level gauge SSR-05

TENSE SSR-05 liquid level control relay for wells, tanks, reservoirs or boreholes. Domestic surface and submersible centrifugal water pumps are usually equipped with thermoplastic hydraulic components and cannot operate without water in "dry friction" conditions even for a short time. Water not only lubricates the friction surfaces but also acts as a coolant, absorbing and dissipating heat generated by friction. A centrifugal pump must be protected against possible dry running or lack of water. Potentially dangerous applications for centrifugal pumps due to the risk of dry running include pumping water from wells or boreholes where the flow rate is low or insufficient, pumping water from tanks or reservoirs with limited or replenishable volumes, and operating in pressure boosting systems. An intelligent pump without functional protection cannot independently detect a lack of water in the suction line or well and shut down. The SSR-05 well, tank, reservoir, or borehole water level monitoring relay is a simple and reliable device for monitoring the water level in a well using two or three level sensors, with adjustable sensor sensitivity and an LED indicator for the well/reservoir water level. The SSR-05 relay can also be used to control a pump for filling a tank or to indicate leaks and pump shutdowns. Therefore, it is preferred for protecting a pump that is at risk of running dry or running out of water in its suction line. The SSR-05 relay for checking the liquid level in a well, tank, reservoir, or borehole is one of the devices that can reliably eliminate the potential risk of a pump running dry.
