Buildmet Technologies manufactures Water Level Controller. Buildmet Technologies offers electronic products in wide ranges. Water Level Controller senses the inputs from the tank, sump and the motor. Depending on the level of water in the overhead tank and the sump, the motor is turned on when the level in the overhead tank goes low. In case the sump level is low or if the motor is sensed as dry running, the output is turned off to prevent motor burn out.
