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

• “Half union” style fittings for quick disassembly, aides in cleaning and/or replacement.
• Annealed cast acrylic for enhanced strength and chemical resistance.
• Dual taper detects for maximum flow range (>10,000:1 turndown)

Detectable flow range:

• 50 ml/min to 10,100 ml/min
• 0.80 GPH to 160 GPH

Visual Indicators:

• 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 foot valve filter
• Chemical has been exhausted for a lengthy period of time
