Rotator Flow Meter (GPE 2001)

ROTATOR FLOW METER

The F2001 Bi-Rotator Flow
Meter is a positive displacement meter utilized in the most demanding applications
requiring accuracy, long life and ruggedness. It owns two precise machinedhelical rotators which share the same size. The two rotators rotate together atthe same speed in the measuring chamber and divide the flowing stream intosegments with equal volume which is precisely designed, and the segments willjoin back into one stream on the outlet side of the FlowMeter. By counting thesegments through the meter, the flow can be calculated. The rotationstatus is transferred to thetotalizing register or the transmitter for recording and calculation. Volumeindication is determined by mechanical output gearing leading to mechanicalregister and F9005 Signal Generator.High accuracy is attained bytwo unique helical rotators which feature two finely balanced rotaters (Referto Figure 1). An adjustor, incorporated on the meter, is used to assure maximumaccuracy within the meters flow range.
