Emerson Fisher rotary gauges can be used on stationary or mobile tanks to visually indicate the amount of Anhydrous Ammonia (NH₃) in the container. They are also used in filling the tank to the proper liquid level. On mobile applications and some large stationary storage tanks, hangers are recommended to support the horizontal length of the dip tube.
The gauge is operated by opening the small bleed orifice when the tube is in the vapor space of the tank. Moving the pointer on the dial causes the end of the tube to move until it contacts liquid in the container. At that point, discharge from the bleed orifice turns from vapor to liquid and the rotary gauge dial gives the volume percentage of liquid the tank.
Note: Gauges fit 1 in. coupling container connections. All gauges have stem and dip tubes with an extra large inside diameter. This assures that the correct liquid level can be obtained quickly.
