KL-233I Dual Pump (Water Tank) Cascade Water Level Controller

Description

This water level controller manages two pumps for cascade water lifting, pumping water from a well to a high-level water tank. When the elevation difference between the well and final tank is large, a single pump struggles. The system adopts a two-stage transfer: Pump 1 delivers water from the well to intermediate Tank 1, then Pump 2 transfers water from Tank 1 to target Tank 2, cutting the head requirement for each pump by half. It detects water levels of both tanks to automatically control pump operation, maintaining proper water levels. It also protects pumps from dry running and frequent start-stop.
