About the 30-3210
The hydrocarbon liquid/water sensor is used primarily in monitoring wells with fluctuating ground water tables
or in containment areas of tanks, pumps and pipes.
The hydrocarbon liquid/water sensor contains a carbon/polymer material that changes its resistance when
exposed to liquid hydrocarbons. It also has a water sensor that relies on the conductivity of water to detect its
presence and allows the 30-3210 to distinguish between hydrocarbon liquid and water.
The sensor also alerts the system to the absence of ground water in a monitoring well or the presence of water
in containment areas. It will alert the system if any fuel leaks into the containment area. In the event of a break
in the cable the system will activate the alarm.

*Maximum Wiring Length is the maximum length of cable to be used to connect all sensors on an individual
channel. The length includes the run of cable from the VSmart Module to each sensor board in the string.
NOTE: To ensure safe operating conditions the sensor has been designed to connect to OPW Fuel
Management Systems’ controllers only.
