Anil Engineering’s Rotogauges help in delivering an accurate determination of LPG or other liquid contents in the container. The gauge is mounted in a standard coupling on a large mobile or stationary container. The Rotogauge’s operation depends on the opening of the vent valve, which leads to the dip tube to rotate from the container’s vapour space to the liquid space. When there’s a difference in the appearance of the distance, the liquid level’s indication takes occurrence. The dial readings in the gauge help operates to see the percentage of product present in the container.
