Designed to visually display the contents of a tank, a fuel tank level gauge is a must have piece of equipment on a storage tank to provide the owner with information on how much fuel is left in their tank, and consequently when they need to order more. Generally speaking, fuel tank gauges provide a simple and easy visual indication on when the fuel is running low, however they are often combined with a fuel tank alarm that will let off a sounder when a pre-set low level is hit. Within our range are tank level indicators designed for both commercial diesel and domestic heating oil applications.
