1.0 Introduction
Alpha Technologies’ Remote Fuel Quantity Alarm system utilizes non-invasive Hall-effect sensing
modules to monitor fuel levels in Liquid Propane Gas (LPG) tanks equipped with “Remote Ready”
fuel gauge dials. The sensing modules transmit a ratiometric voltage output proportional to the liquid
volume in the cylinder. This voltage is detected and summed by the Fuel Alarm Quantity Relay circuit.
When necessary, the “Total Fuel Half Full” relay (Normally Closed or Normally Open “Form C” dry
contact) activates a Fuel Level alarm at the customer’s monitoring facility.
