These float-operated gauges are suitable for oil and diesel/fuel tanks, specifically designed for 4-foot tanks. Additionally, an adjustable universal version is available, accommodating tanks up to 2 meters deep, with adjustments made via a screw control on the side of the dial face cover.

Operating as per their name, these gauges feature a float that moves up and down with the oil level. Connected to the gauge atop the tank via a string, the float’s movement determines the gauge’s reading. These gauges are commonly referred to as float-on-a-rope or cat-and-mouse gauges.

Please note: Some sizes come with a square body while others feature a round body. The universal version measures in centimetres instead of displaying the ‘Full-3/4-1/2-1/4-Empty’ markings found on fixed-depth versions.

To simplify installation, a ‘Combivent’ fitting is available, which fits over a 2-inch vent pipe and provides a 1-1/2-inch female thread for easy screwing of the gauge. The gauge itself features a 1-1/2-inch BSP male threaded attachment for tank mounting.
