Description The Veeder-Root 794380-352 Discriminating Containment Sump Sensor can quickly and accurately detect the presence of hydrocarbons or fluids and differentiate between the two, in their respective locations. Alarm conditions - Fuel, Liquid Warning, High Liquid Alarm, Sensor Out - detected by either sensor are indicated by an audible alarm, a displayed message, and a printed message on the TLS-350R or TLS-350. They are also recorded as part of the TLS-350R or TLS-350 Alarm History Report. The housing is constructed of polyester, the sensing element a conductive elastomer. The sensors can be reused after an alarm condition is sensed, without degradation to the sensing materials. Includes: Installation Kit P/N 330020-440Mounting brackets are required.
