- Available Lengths Up to 25'
The LVLK500 groundwater sensor can be incorporated with associated electronics to meet EPA requirements for out-of-tank product detection. It detects as little as 1/32" of floating hydrocarbon product on the water table. Designed for observation wells up to 25' deep, a float-type liquid level switch switches OFF when it detects a drop in the water table below the hydrocarbon sensor. In addition, a polymer strip is incorporated into the LVLK500 to also indicate the presence of hydrocarbons. The LVLK500 responds to gasoline within ten minutes. Response time for other hydrocarbons, the C5 to C16 range, takes longer. For example, response time for diesel is up to one hour. A watertight cap prevents spilled fuel from entering the well.
The entire unit is easily removed for periodic inspection. If the probe comes in contact with hydrocarbon, simply allow it to air out and reuse. These units are recommended for installation in non-contaminated sites only; they are not designed for remediation applications.
To detect liquid hydrocarbon, LVLK500 well monitoring sensors incorporate an innovative polymer strip that continuously conducts electricity when voltage is applied. Extending longitudinally within the unit's protective braiding, the polymer strip physically swells on contact with liquid hydrocarbons anywhere along its length. The swelling causes a dramatic increase in the electrical resistance of the polymer, and may be used as a switch when incorporated with associated system electronics. When allowed to recover outside the well, the polymer reverts to its normal conductive state for reuse. In absence of hydrocarbons, the polymer strip has a base resistance of 0.8 to 3.0 k ohm/ft.
