Blue-White’s Micro-Flow flow verification system is designed for use with a metering pump to provide accurate flow measurement and accumulated flow data. Empty chemical tanks, clogged injection fittings, lost prime, and other problems can prevent a properly working pump from injecting chemical. The unit can be connected directly to Blue-White A-100NV and C-1100V metering pumps. It may be installed directly into the pump’s discharge tubing, inline in the system after the pump, or mounted to a panel. If chemical should fail to inject, the pump will stop and an alarm relay will close, allowing for remote alarm indication or initiation of a back-up injector pump.
