1" Rotogages® for Large Mobile and Stationary Containers

      Rotogages® are designed to provide an accurate determination of LP-Gas or anhydrous ammonia container contents. They mount in a standard 1" NPT coupling on large mobile or stationary containers.
      To operate the Rotogages®, the vent valve is opened and the dip tube rotated slowly from the container vapor space to the liquid space. The difference in appearance of the discharge indicates when the liquid level is reached. Dial readings then indicate the percentage of product in the container.

3⁄4" Rotogages® for Small Stationary and Mobile LP-Gas Containers

      Rotogages® are designed to provide accurate determination of LP-Gas container contents. They may be end or side mounted in a standard 3⁄4" NPT coupling on stationary or mobile containers. To guarantee accurate measurement, they should not be used on stationary containers that exceed 60" I.D. or on mobile containers, subject to vibration, with an I.D. of more than 24".
