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 794380-320 sensor is a solid-state discriminating sensor that detects the presence of fluid as well as whether the fluid is water or fuel. The sensor contains two solid-state sensors which are used to activate either a high level or low level alarm. The 794380-322 sensor is a discriminating sensor that detects the presence of fluid as well as whether the fluid is water or fuel. The sensor contains two float switches which are used to activate either a high level or low level alarm switch. The 793480-320 and 794380-322 sensors also contain a product sensitive polymer strip that discriminates between conducting liquids such as water and non-conducting liquids such as hydrocarbons. If the liquid level rises above the threshold of the lower sensor on either of the sensors in the dispenser pan, an alarm condition is generated indicating there is a low level liquid alarm in the dispenser pan. If the liquid level rises above the threshold of the upper sensor on either of the sensors in the dispenser pan, an alarm condition is generated indicating there is a high level liquid alarm in the dispenser pan. If fuel rises above the threshold of the discriminating polymer strip, a fuel alarm will be generated indicating that fuel is present in the dispenser pan.
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=7871
