Float level gauges to measure levels in LPG and NH3 tanks and containers

Float level gauges are simple devices that measure liquid content in the likes of ISO containers, domestic tanks, bottles, storage tanks, trucks and trailers. A float level gauge is also greatly used in compressors, generators and agricultural and construction machinery.

Product description

How does a float level indicator work? As the content levels of the container changes, the float level gauge's floatable device actuates a magnet to move a dial needle that displays the content levels. To choose the right float level gauge for your situation, you need to look at mounting position, liquid viscosity and the size and position of your tank. All these factors highly influence the right choice of float level gauge.

    Bypass level indicators

    These indicators allow you to monitor gas or liquid levels in a tank using a display with plastic rollers that correspond to the location of a magnet. Their robust design ensures a long lifespan.

    Consisting of a dip tube, dial gauge and a vent valve, rotogages provide a simple way to read the liquid level of tanks. They are often mounted to the end of the container at the halfway mark.
