The IP100/200-Series are adjustable depth insertion paddlewheels that come in brass, PVC, or 316 stainless models to fit 3” to 40” pipe. Adapters mate with standard 1-1/2” (11x/21x) or 2” (15x/25x), or PVC (11x/21x) NPT threaded fittings such as saddles and weldolets which may be purchased either locally or from Seametrics.
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.
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 (IP15x/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.
