The Model TG-EL-D5 Multi-Tank Gauge and Leak- Detection System is a comprehensive system that can simultaneously monitor product levels and leaks. The Model TG-EL-D5 combines digital monitoring and control technology with Preferred’s line of tank gauging and monitoring equipment. The system provides the best solution for a variety of gauging and leak-detection applications. Intuitive displays operate on a simple menu system providing quick and easy navigation for all of the Model TG-EL-D5’s features. The 16-line by 40 character LCD display is backlit to provide easy visibility of tank contents, leak sensor status and alarms. The Model TG-EL-D5 is applicable to a wide range of tank gauging applications. It accepts the wire float, Model TG-EL-WF for applications with liquid depths of 12 feet or less, and may accept ultrasonic or differential pressure sensors for larger depth liquids. Using the discriminating leak sensor, Model HD-A-C the Model TG-EL-D5 monitors both steel and fiberglass double wall tanks, double wall piping, tank manholes and/ or vaulted tank containment areas. The Model HD-A2-C sensor provides both local and remote oil and water leak detection.

Inventory Management

The Model TG-EL-D5 provides product level and volumetric data for each tank and maintains a delivery log with time/date stamp, product quantity and tank number.

Annunciation

The Model TG-EL-D5 provides high level and leak alarm monitoring. Alarms are visible on the tank status display, activate the integral alarm horn and are logged with time/date stamp and English language description on an alarm summary display. Monitored alarms include: overfill alarm (high level), low level alarm (time to refill), and leak alarm. 

Fuel Transfer System Integration

The TG-EL-D5 may be fully integrated into Preferred’s Automatic Fuel Oil Transfer Pump Set. Both pump set and tank gauge status is available on a common LCD display and RS-485 communication port. Up to a two (2) tank, a Model TG-EL-D5-2 may be integrated into the Automatic Fuel Oil Transfer Pump Set. Consult the factory for larger systems.
