Oil Tank Gauge Reading 101

Before checking your heating oil level, it's important to know how the judge works. Many oil tanks utilize a float-manner gauges.

Most gauges use rigid metallic rods that are attached to a float within the oil tank. When the tank is total, the float rises and pushes upwardly a disk to the top of the gauge. As the oil is used, the float falls accordingly, and the gauge level drops.
