Abstract
A flow indicator and a method for monitoring the operation of a chemical feed pump are provided. This indicator includes a housing defining a flow chamber and having an inlet through one end and an outlet through the other end. The inlet and the outlet of the housing are in communication with the fluid conduit of the pump, and the flow chamber is a vertical component of the flow path of the fluid flowing through the conduit. The housing contains two freely movable balls in the flow chamber, one ball having a specific gravity greater than that of the fluid and the other having a lower specific gravity. It is at least partially transparent to enable the operator of the indicator to observe the movement of the balls. The method for monitoring the pump involves placing the two balls in the flow chamber, connecting the indicator to the fluid conduit, operating the pump, and observing the action of the balls.
