The F2001 Bi-Rotator Flow Meter is a positive displacement meter utilized in the mostdemanding 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. ![]()
