How to Monitor Fuel Levels in a Generator?

Monitoring Fuel Levels

To accurately monitor fuel levels, you can install a fuel level sensor, such as those available from companies like Sensi or Nixie. These sensors can be connected to a generator’s oil level gauge or fuel tank and provide real-time information on fuel levels. For example, the Sensi fuel level sensor can be mounted on a 1/4-inch NPT port and is suitable for use with gasoline, diesel, and biodiesel fuels.

Checking Fuel Levels Manually

Alternatively, you can check fuel levels manually by observing the fuel level indicator or gauge on your generator. Typically, the gauge is located on the control panel or near the fuel tank. For example, a 15 kW diesel generator may have a fuel gauge that indicates fuel levels from empty to full, with markings at 1/4, 1/2, and 3/4 tank. It’s essential to check the fuel level regularly, especially if you’re running your generator for extended periods.

Tri-Fuel Generators

Some generators, like the Cummins Onan RV QG 3800 tri-fuel generator, allow you to run on natural gas, propane, or gasoline. When monitoring fuel levels in a tri-fuel generator, you need to consider the specific fuel type and the generator’s fuel tank capacity. For instance, the QG 3800 has a 20-gallon fuel tank and can run for up to 14 hours on a single tank of gasoline. By understanding your generator’s fuel tank capacity and monitoring fuel levels regularly, you can prevent fuel-related issues and ensure your generator runs efficiently.
