The TX100/200-Series are adjustable depth insertion turbines flow sensor that come in brass or 316 stainless models to fit 3” to 40” pipe. Installation fittings are standard 1-1/2″ (101/201) or 2” (115/215) FNPT. Fittings such as saddles and weldolets may be purchased either locally or from Seametrics flow meter.
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.
If desired, a modular system of electronics can be installed directly on the flow sensor or mounted remotely. The FT415 (battery powered) or FT420 (loop powered) provides digital rate and total display, as well as programmable pulse; the FT420 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 (TX115/215) 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.
