Flow Indicator

The Flow Indicator is an excellent diagnostic tool for chemical feed pumps.

Rhythmic rising and falling of the ball indicates positive flow.

Air bubbles indicate chemical has exhausted.

Stationary ball indicates no flow.

Possible problems could be:

lost prime
stopped motor
plugged injection fitting
faulty tube or diaphragm
plugged or dirty footvalve filter
chemical has been exhausted for a lengthy period of time

Blue-White recommends using:

Glass bobbin for Chlorines and Acids
Stainless Steel bobbin for soaps and waxes (high viscose fluids)
