+GF+ Signet Rotor-X Paddle-Wheel Flow Sensors

Open-core design ensures accurate, linear output to ±1%
  • Eliminate cavitation and minimize pressure drop
Sensors contain an open-core rotor with a small magnet in each of the four blades. As they rotate, the magnets pass a coil in the sensor. The transducer generates a linear frequency output that is proportional to the flow velocity. This signal travels up to 200 feet without amplification.

Open-core design eliminates cavitation at flow velocities from 1 to 20 ft/second. Closed or solid paddle-wheel designs create air bubbles at these velocities, causing a nonlinear, nonrepeatable signal.

Sensor materials resist most chemicals. All models have PVDF rotor and VITON® O-ring; and include a 25-ft connecting cable.

ROTOR-X flow sensors are compatible with all of our line-, battery-, and sensor-powered flowmeters, accumulators, and controllers. Mount in any type of pipe using an installation fitting—order separately.
