LNG or Hydrogen Vehicle Fuel Gauge System

System Overview

The AMI LNG vehicle fuel gauging system is designed specifically for mobile vehicles such as trucks or buses operating on LNG fuel. This same technology also has application on Hydrogen fuel cell vehicles. The system consists of a integral level sensor mounted inside the tank, an electronics module, standard analog dash mounted gauge and cables. The electronics module is designed to be bolted onto the truck chassis with cables connecting to the power source, tank sensor, and dash-mounted gauge.

Advanced Electronics

The electronics are microprocessor-based, compact, and have low power requirements. The electronics are rated for an operating environment of - 40 to + 85 ^oC.  The LNG vehicle gauging system is designed to operate on 12 Vdc power and has built-in overvoltage startup/jump start protection that keeps the instrument operating during and after such conditions occur. The gauging system includes a standard 2-1/8" dash mounted  type LNG fuel gauge, power wiring, signal wiring and a cable for connection to the sensor. The electronics module is  mounted to the chassis via supplied mounting studs and is housed inside a NEMA 4 fully weather-proof enclosure. The electronics is calibrated at the AMI factory. No calibration is necessary during or after installation. Wiring is simple and easy. This means that electronics enclosures can be installed or changed in the field without any complicated calibration process. The unit is designed to withstand 12 Vdc miss-wiring without damage.
