GENERAL INFORMATION
The TX800-Series are insertion turbine meters designed for use
in 1-1/2” to 8” pipe and are available in 316 stainless steel,
brass, and PVC sensor bodies, machined from solid rod for
maximum low-fl ow performance. The TX800-Series use special
fi ttings that ensure ease of installation and correct depth setting
in the pipe.
Ruby bearings and a non-drag Hall-effect sensor give these
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 long
distances (up to 2,000 feet) without a transmitter. This signal
can be connected directly to Seametrics controls and displays,
as well as PLC’s, counters, and computer cards.

Seametrics TX800 meters are ideal for chemical proportioning
applications. If no display is required, a simple divider such as
the PD10 provides adjustable pump pacing. For rate and total
display, as well as pump pacing, 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.
