RotorFlow - RFI-Types, Visual Indicators
Specialist designs are available based on your requirements. Please contact Sales Office for
further details on options such as potable water, enhanced chemical capabilities or 4-20mA loop
powered units.
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 new bayonet mounting lens is easily removed for quick
cleanout. RFI Type RotorFlow sensors are easy to see, easy to install and easy to afford.
