Level Measurement

We offer a range of level sensing measurements to fit your application. Low-cost, single point control systems provide high or low setpoint control. Multiple point controllers provide high and low setpoint control or other parameter control as desired with pumps, valves and alarms. Continuous level controllers provide a proportional output that tracks sensor measurements over a predefined range. Select from a range of sensors to meet your installation requirements and fluid compatibility.
