Gems RotorFlow RFS-2500 Series Instruction Bulletin

(For Additional Information, See Gems' "Level, Flow and Pressure Catalog)
RotorFlow units monitor dynamic fluid flow. The rotor reacts to
turbulence, pulsation, entrained air, and other flow anomalies induced in
the flow stream by other process hardware. For optimum performance,
install RotorFlow units where nominal flow conditions exist, with ports
located at the top. Incoming flow may be placed to either port. A
minimum of 8" of straight pipe on the inlet side is recommended.
Low Flow Applications
A low flow adapter is supplied with all RotorFlow units. It is used to produce accurate response at low flow rates. Press fit the
adapter as shown above, in the port selected for incoming flow. See Flow Range Chart below.
