Flow Rate Monitoring
Quick Specs...
Overview / Design Principle:
Gems Sensors popularized the RotorFlow’s paddlewheel design by combining high visibility rotors with solid-state electronics that are packaged into compact, panel mounting housings. They provide accurate flow rate output with integral visual confirmation...all with an unprecedented price/performance ratio.
