In handling liquids where a continuous rate of flow is an operating aid and necessity, it is desirable to know at a glance the rate of flow in GALLONS PER MINUTE. With the Flow Rate indicator which has a clear Pyrex® tube entirely around the body and an indicator just inside the tube for easy reading, the rate of flow in GALLONS PER MINUTE is observable at all times. The flange of the float deflects the liquid against the wall of the tube and helps kEFI it clean and the indicator remains visible even in liquids of high sediment content. The small size of the flow rater permits minimum line spacing.
