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 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. High accuracy is attained by
two unique helical rotators which feature two finely balanced rotaters (Refer
to Figure 1). An adjustor, incorporated on the meter, is used to assure maximum
accuracy within the meters flow range.

Features:

• Accuracy up to 0.1%,
  over 10:1 turn-down ratio
• Extremely long service
  life and easy maintenance
• Self-lubricating, low
  pressure drop, and low noise and vibration
• Two unique helical
  rotators with no touch, but synchronized by timing gears in the measuring
  chamber
• No oscillating, reciprocating
  or sliding parts or cranks to wear or disturb the balanced rotary action
