RFI Type Visual Flow Indicator

Brand: Gems Sensors, Inc

This is RotorFlow in its most basic form a bright orange rotor turning with fluid flow. Simple, direct and reliable.

Flow rate is estimated, or simply confirmed, by viewing the speed of the turning rotor. Either port may be used for incoming flow, and bayonet mounting lens is easily removed for quick cleanout. 

RFI Type RotorFlow sensors are easy to see, easy to install and easy to afford.
