Tank Monitoring

PRODUCTS

Fil-A-Larm Caution Sign
Model FA-S, Fil-A-Larm Caution Sign – Installed near the FA-AV Alarm System or Model 2 In-Wall Spill Container, this sign reduces the possibility of tank overfilling by alerting the operator to the presence of the Fil-A-Larm System and Model 2 In-Wall Spill Container.

Fuel Sentry Tank Gauge and Leak Detection System
Model TG-EL-D4A, Fuel Sentry Tank Gauge and Leak Detection System – Designed for use with all fuel oils (No. 2 through No. 6), diesel, kerosene, jet, and most other petroleum products. Tank gauges are required by NFPA 30 Flammable and Combustible Liquids Code and NFPA 31 Standard for the Installation of Oil-Burning Equipment, and NFPA 110 Standard for Emergency and Standby Power Systems.

HD-A1 Oil & Water Leak Detector
Model HD-A1, Leak Detector – Installed in the interstitial area between two tank walls, or in the containment basin of a single wall tank to detect both oil and water leaks. For use with TG-EL-D3 or TG-EL-D5 Tank Gauge and Leak Detection Systems.

HD-A2C Oil & Water Leak Detector
Model HD-A2-C Leak Detector – Up to six HD-A2-C Leak Detectors can be connected to a single TG-EL-D4A Tank Gauge and up to 12 Leak Detectors can be connected to a single TG-EL-D5 Tank Gauge.

High Liquid Level Alarm Switch
Model HLS-LF, High Liquid Level Alarm Switch – Used on light fuel oil storage tanks to reliably activate an overfill warning signal.

Liquid Level Switch
Model PLS, Liquid Level Switch – Commonly used on fuel oil day tanks to control the addition of oil from remote pumps, and to alarm high and low levels. Other applications include pressurized or vented tanks for water, hydraulic fluid, lubricating oils or distillate fuels.

Overfill Alarm Station
Model FA-AV, Fil-A-Larm System – Designed to be located near the tank fill terminal to notify of a potential overfill condition. The system triggers a high level alarm that alerts the filling operator that the tank is filled to its predetermined capacity.

Pump Set Leak Detector Switch
Model PS-LDS, Pump Set Leak Detector Switch – Includes the base pan of a pump set, the rupture basin of a tank, or adjacent to a tank in a boiler or engine room.

Rupture Basin Switch
Model RBS, Leak Detection Switch – Detects leakage into day tank rupture basins and double wall piping leak containment systems containing diesel or distillate fuel oils. For easy installation, the Model RBS is designed for side-wall mounting.

Tank Gauge and Leak Detection System
Model TG-EL-D3 Tank Gauge – Remote reading, microprocessor-based tank gauge complete with an integral audible and visual alarm system for leak detection, tank overfill and low liquid level alarm. Designed for use with single wall, double wall and vaulted fuel oil storage tanks and for application to all grades of fuel oil, including No. 6. The TG-EL-D3 System is Factory Mutual Approved and complies with EPA regulations for leak detection and overfill alarm (Federal Register 9/23/88). Factory Mutual Approved

Wire Float Level Sensor
Model TG-EL-WF, Wire Float Level Sensor – Accurate, easy to install, and ideal for low “Head Room” installation applications. For use with TG-EL-D3 or TG-EL-D5 Tank Gauge and Leak Detection Systems.
