Pool water level controller ELV-POOL series

Pool water level controller ELV-POOL series

The ELHART ELV-POOL controller is a dedicated solution designed for water level control in overflow swimming pools. It seamlessly fitting into the ELHART family of modular, DIN-rail mounted controllers.

Water level monitoring is precisely handled by 4 conductive probes, while the operational logic of the outputs is reliably determined by a built-in control algorithm.
