Interstitial Hydrocarbon Liquid Sensor Installation
The Interstitial Hydrocarbon Liquid/Water Sensor is designed for use
in the interstitial area of a fiberglass double-walled tank. The
hydrocarbon liquid/water sensor contains a carbon/polymer material
that changes its resistance when exposed to liquid hydrocarbons.
Additionally, it contains a conductive strip to detect the presence of
water, providing the ability to discriminate between hydrocarbon liquid
and water. In the event of a break in the cable, the system will activate
the alarm.
