Specificity Results (in addition to above):
Sensors will respond to any hydrocarbon liquid after its threshold is exceeded.
Comments:
Sensors are reusable. Sensor is easily removed, cleaned, and reinstalled.
The consoles in the 8601 Series are identical other than their name for marketing purposes. Each of the consoles within the series will perform identically.
The 8601 Series consists of the following derivatives: TLS4, TLS4B, TLS4c, TLS4i, and TLS-S1 consoles.
The 794380-343 sensor is a solid-state discriminating interstitial sensor for fiberglass tanks (4’ to 10’ I.D.) with a 25’ long cable. The sensor detects the presence of fluid in the interstice of a fiberglass tank and can determine whether the fluid is water or fuel. If the liquid level rises above the threshold of the sensor in the interstice of a fiberglass tank, an alarm condition is generated indicating whether the liquid is water or fuel.
The 794380-345 Solid-State Interstitial Sensor for Double-wall Fiberglass Tanks detects the presence of fluid in the interstitial space of double-wall fiberglass tanks. The sensor consists of an optical sensor for detecting hydrocarbons and water. If the liquid level rises above the threshold of the sensor in the interstice, an alarm condition is generated. This would indicate there is liquid present in the interstice where the sensor is installed.
For both sensors, console alarm is indicated by an audible alarm, a displayed message and a printed message (if the console is equipped with a printer.) The alarm is also recorded as part of Alarm History Report.
Discriminating sensors listed herein that come into contact with gasoline or diesel fuel require cleaning. For cleaning procedures, reference Veeder-Root Manual 577013-814 at: http://www.veeder.com/gold/download.cfm?doc_id=78711
