Ruby bearings and a non-drag pickoff give these adjustable insertion turbine flow sensors a wide flow range and long life. A sensor detects the passage of miniature magnets in the rotor blades. The resulting square-wave signal can be sent for hundreds of feet without a transmitter, over unshielded cable. This signal can be connected directly to many PLC’s and other controls without any additional electronics.
A modular system of electronics can be installed directly on the flow sensor or mounted remotely. The FT430 (externally powered with a pulse), FT440 (loop powered), and FT450 (battery powered) all provide digital rate and total displays, as well as a programmable pulse; the FT440 also provides a 4-20 mA analog output. The AO55 is a blind analog (4-20 mA) transmitter. Programmable pulse for pump pacing is available with the PD10.

The “hot-tap” models (TX15x/25x) can be installed or serviced without shutting down the line by means of a 2” full-port isolation valve that comes with a nipple for installation on the pipe fitting. In most circumstances, no special tool is required.
