The Blue-White FI-100-6V Flow Indicator is a genuine OEM visual flow device designed for aggressive chemical metering systems. Built with a clear body and a glass bobbin float, it allows field technicians to instantly verify chemical flow in suction tubing sized for .37-inch outer diameter. When fluid is pumped through the tubing, the bobbin rises and falls—providing a clear visual cue of proper flow. If the bobbin remains stationary, it’s a sign of no flow, helping diagnose issues like lost prime, blocked tubing, faulty foot-valves, or exhausted chemical supply.

Features:

• Genuine Blue-White Industries flow indicator
• For use with .37-inch outer diameter tubing (approx. 3/8 inch)
• Clear body with Viton/glass bobbin float for chemical resistance and visual clarity
• Designed to mount on the suction side of chemical-feed pumps
• Provides instant visual confirmation of flow—bobbin rises/falls when fluid moves
• Helps detect: no flow, lost prime, blocked tubing, or depleted chemical supply
• Compatible with many Blue-White peristaltic & diaphragm pump models
