GENERAL INFORMATION
The TX100/200-Series are adjustable depth insertion turbines
that come in brass or 316 stainless models to fit 3” to 40”
pipe. Adapters mate with standard 1-1/2" (110/210) or 2”
(150/250) FNPT fittings such as saddles and weldolets which
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 (TX150/250) can be installed or ser-
viced 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.
