  • Measure low flow rates down to 0.3 ft/second
Measure low flow rates in almost any size pipe. These sensors contain an open-core rotor with a small magnet in each of the four blades. As they rotate, the magnets pass a Hall effect sensor, which generates a linear frequency output that is proportional to the flow velocity. This signal travels up to 1000 feet without amplification.
The open-core design eliminates cavitation at flow velocities from 0.3 to 20 ft/second. Closed or solid paddle-wheel designs create air bubbles at these velocities, causing a nonlinear and 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 low-flow sensors are compatible with all of our line-powered flow indicators, accumulators, and controllers. Mount in any type of pipe. Order installation fittings separately.

  • Q:

    can this flow meter be setup with an analog input card to produce a 4-20 mA signal
    Asked on 12/12/2013 by kenny from PARIS TX

    1 answer



      This flow meter is designed to be connected to a flow transmitter/controller, such as 56560-12. This transmitter has a 4-20 mA output standard, so no additional input card would be required.
