Veeder-Root Sensor Application Guide 1 Discriminating Dispenser Pan and Containment Sump Sensors The appropriate sensor can be installed in a dispenser pan or in a containment sump and will detect the presence of, and differentiate between, hydrocarbons and other liquids. Three types of sensors are available (Standard, Optical and Mag Sump). See table for sensor features and console compatibility: Sensor Detection Capabilities - Alarm Conditions • Fuel at any height on the sensor, even when floating on other liquids, triggers a Fuel Alarm. • Liquid Warning is triggered when liquid reaches a nominal height of 1 inch on both Dispenser Pan and Containment Sump sensors (except Mag Sump sensor - Water Warning occurs at 1.7 inches). • High Liquid Alarm is triggered when liquid reaches a nominal height of 8 inches on Dispenser Pan or 10 inches on Containment Sump sensors (except Mag Sump sensor). • An open sensor triggers a Sensor Out Alarm on standard and optical sensors and a Comm Alarm on Mag Sump sensors. Measurement Sensor Type Standard Optical Mag Sump Fluid height Float-triggered switches Optical sensing at trip points (no moving parts) Floats along sensor length Hydrocarbon/fluid differentiation method Conductive elastomer Conductive elastomer Floats Operating temperature: 0 to +70°C -40 to +70°C -40 to +60°C Compatible consoles TLS-450, TLS-350R, TLS-350Plus, PC-350R, PC-350Plus, TLS-350J, TLS-300i, PC-300i, and TLS-300C, i, J and PC kits TLS-450, TLS-350R, TLS-350Plus, PC350R, and PC-350Plus TLS-450, TLS-350R, TLS-350Plus, PC-350R, and PC-350Plus Console software version compatibility TLS-3XX (Version 8 and later) TLS-450 (All versions) TLS-350 series (Version 2 and later) TLS-450 (All versions) TLS-350 series (Version 24 and later) TLS-450 (All versions) Sensor Interface Interstitial/Liquid Sensor Interface Module P/N 329358-001 (not required for TLS300 series consoles) Type B Interface Module - P/N 329950-001 (TLS-350 series) Smart Sensor - P/N 329356-004 (TLS-350 series) Universal Sensor Module (USM), P/N 332812-001 (TLS-450) USM, P/N 332812-001 (TLS-450) USM, P/N 332812-001 (TLS-450) Maximum number of sensors monitored per console TLS-350 Series Consoles (except TLS350J) - 8 per Interstitial Module (64 max.); TLS-350J - 3 max.
