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.
