About Vahra Technology Fully automatic water level controller (CRAB - 2 Kit) with all protections Pump Controller
This fully automatic water level controller for dual tank this is suitable for both overhead and underground tanks. It works with MCB type starters and without starters. The device monitors water levels, protects the motor from dry run, overload, and high/low voltage, and saves water, time, and energy. Only two wires are required for installation.This controller turns the motor ON/OFF automatically, protects from high/low voltage and dry run, and displays water levels in both tanks (Low, 25%, 50%, 75%, 99%). It also indicates motor errors for quick troubleshooting. Suitable for motors up to 2HP.
