The Blue-White FI-100-4V 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 .25T 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.
