Ruby bearings and a non-drag pick-off give these adjustable insertion flow sensors the widest flow range
of any of the paddlewheel types. A Hall-effect device detects the passage of miniature magnets in the
six rotor blades. The resulting square-wave signal can be sent hundreds of feet without a transmitter,
over unshield cable. This signal can be connected directly to many PLCs and other controls without
A depth adjustment system allows two basic sizes
to cover pipe sizes from 7.62 to 102 cm (3 to 40").
