GENERal INfORMaTION

The TX100/200-Series are adjustable depth insertion turbines

that come in brass or 316 stainless models to fit 3” to 48”

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.

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 ro-

tor 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 isola-

tion valve that comes with a nipple for installation on the pipe

fitting. In most circumstances, no special tool is required.
