The Flo-tech quad series turbine flow sensors are derived from the FSC series, utilizing two flow transducers which are 90° electrically out of phase from each other. With the addition of a second flow transducer, it is possible to monitor flow in both directions. The F2000 quad is suitable for up-down counters that can discern the leading and trailing edges of the quadrature signals.

The F2000 can be used as a speed-sensing device on mobile equipment in current applications. This bi-directional flow sensor can be used as a governor, sending frequency signals back to a PLC, which enables it to make the necessary adjustments. Other functions of the flow sensor are in linear applications where accurate positioning is required. Pressures up to 5000 psi, temperatures up to 300°F. Accuracy ±1% of FS for forward and reverse flow with ±0.2% repeatability.
