Hydrocarbon Liquid/Water Sensor
Part # 30-3210-nn
The hydrocarbon liquid/water sensor is used primarily in monitoring
wells with fluctuating groundwater tables, or in the containment areas
of tanks, pumps and pipes.
The sensor contains a carbon/polymer material that changes its
resistance when exposed to liquid hydrocarbons, as well as a water
sensor that relies on the conductivity of water to detect its presence,
providing the ability to discriminate between hydrocarbon liquid and
water.
The sensor also alerts the system to the absence of groundwater in a
monitoring well, or the presence of water in containment areas. It will
alert the system if any fuel enters into the containment area, which
would indicate a leak. In the event of a break in the cable, the system
will activate the alarm.
