The Model HSS 1056 Floating Oil Thickness Monitor consists of a unique sensing probe that continuously monitors a water surface to control pumps, operate valves, or activate alarms.
The capacitance technology does not foul or require cleaning. There are no moving parts and the remote alarm unit mounts safely away from wetted parts.
The sensing probe monitors the capacitance field between the probe and it’s concentric shield. As the volume of separated oil increases on the water surface, the probe capacitance changes. This proportional change is used to indicate the separated oil level and provide relay control and outputs.
