Rotogage for gauging of LPG/NH3 levels

The Rotogage accurately determines the liquid level of Propane/Butane tanks or NH3 containers. They are usually mounted on the tank side or the end of small to large mobile and stationary containers.

Product description

Consisting of a dip tube, dial gauge and a vent valve alongside the handle, the rotogage can indicate the percentage of liquid occupying a tank by readings where vapour exits the vent. Rotogages are normally installed at the 50% mark of a tank.
