GPE Model F2001 series Bi-Rotator Flowmeter apply pure mechanical structures which guaranteed extream precision and long life-time. Our helical rotators were machined under highest standard which guaranteed (interior housing volume to be constant during measurements) the precision of measurements. Direct mechanical output eliminates further error (caused by signal degrades) in electronic devices. Learn more>>

Meter Registers
Explosion-proof digital totalizer and flow indicator with optional RS485, pulse output and/or 4 to 20mA output
Mechanical meter register with 6 figures non reset type tantalizer (5 on digits plus 1 on dial)
Mechanical meter register with 5 large figures, 8 digits no reset type totalizer, 5 figures resettable through single handle


• Superior accuracy ±0.1%, over 10:1 turn-down ratio

• Extremely long service life

• Self-lubricating, low noise and vibration

• Two unique helical rotators with no touch, but synchronized by timing gears in the measuring chamber

• Uniform rotation means low pressure drop

• Rugged double case structure prevents loss of calibration due to changes in pressure or temperature

• No oscillating, reciprocating or sliding pars or cranks to wear or disturb the balanced rotary action
