GENERAL INFORMATION
The TX100/200-Series are adjustable depth insertion turbines
that come in brass or 316 stainless models to fi t 3” to 40” pipe.
Adapters mate with standard 1-1/2” (11x/21x) or 2” (15x/25x)
FNPT threaded fi ttings 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 fl ow sensors a wide fl ow 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.
Seametrics Incorporated • 253.872.0284 • www.seametrics.com
A modular system of electronics can be installed directly on the
fl ow sensor or mounted remotely. The FT430 (externally powered
with pulse), FT440 (loop powered), and FT450 (battery powered)
all provide digital rate and total displays, as well as a programmable pulse; the FT440 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 (TX15x/25x) 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 fi tting.
In most circumstances, no special tool is required.

HOT TAP INSTALLATION
Insertion and removal under pressure is possible due to
the 2” full-port isolation valve, which comes with a nipple
for installation on the pipe fi tting. If it is necessary to
do the initial installation under pressure, any standard
hot tap drilling machine with 2” NPT adapter, such as a
Transmate or a Mueller, can be used. Ordinarily, it is not
necessary to use an installation tool, since the smalldiameter tube can be controlled by hand at all but the
highest pressures.
