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 machined helical rotators which share the same size. The two rotators rotate together at the same speed in the measuring chamber and divide the flowing stream into segments with equal volume which is precisely designed, and the segments will join back into one stream on the outlet side of the Flow Meter. By counting the segments through the meter, the flow can be calculated. The rotation status is transferred to the totalizing register or the transmitter for recording and calculation. Volume indication is determined by mechanical output gearing leading to mechanical register and F9005 Signal Generator.
