GeNerAL iNFOrMATiON
The IPFS Series are adjustable depth insertion paddlewheels
that come in brass or 316 stainless models to fit 3” to 40” pipe.
Installation fittings are standard 1-1/2" or 2” NPT. Fittings such
as saddles and weldolets may be purchased either locally or from
Dwyer Instruments Inc.
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 flow sensor or mounted remotely. The Series RTI
provides digital rate and total display, as well as programmable
pulse output; the Series RTI also provides a 4 to 20 mA analog
output. The Series BAT is a blind analog transmitter. Program-
mable pulse for pump pacing is available with the Series PWD.
The “hot-tap” models IPFS-1 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.
