Universal Reservoir Sensor
Use a Universal Reservoir Sensor with hydrostatically monitored
tanks. The Reservoir Sensor monitors the level of the liquid in the
reservoir of a double-walled tank. The sensor has a single float that
detects abnormally high or low liquid levels within the reservoir. If a
leak occurs in either wall of a tank, it causes the liquid in the reservoir
to rise or fall. When liquid reaches the upper or lower limit on the
sensor, the sensor activates.
