Ruby bearings and a non-drag Hall-effect sensor give these meters the widest flow range of any of the paddlewheel types. A sensor detects the passage of miniature magnets in the six rotor blades. The resulting square-wave signal can be sent for hundreds of feet over unshielded cable without a transmitter and connected directly to many PLC’s and other controls without any additional
electronics.
If desired, a modular system of electronics can be installed directly on the fow sensor or mounted remotely. The FT415
(battery powered) or FT420 (loop powered) fow indicator provides digital rate and total display, as well as programmable
pulse output; the FT420 also provides a 4-20 mA analog output. If a display is not required, the AO55 provides 4-20 mA
analog output, and the PD10 provides a programmable pulse for pump pacing.
The “hot-tap” models (IP115/215) can be installed or serviced without shutting down the line by means of a 2” full-port isola-
tion valve that comes with a nipple for installation on the pipe ftting. In most circumstances, no special tool is required.
