The Seametrics TX800 Series of insertion turbine flow sensors is designed for use in pipe
sizes 1-1/2" to 8". High-quality jewel bearings and nickel-bound tungsten carbide shaft offer
maximum life and low friction. Solid rod is machined to form the bodies of the TX800 turbine
flow sensors for maximum precision.
The low flow performance of the TX80 turbine flow sensor is superior. The
rotation of the rotor is detected by a non-drag Hall-effect sensor and then outputted in a
pulse-type square wave, which can be sent long distances (up to 2,000 feet) without a
transmitter. This signal can be connected directly to Seametrics controls, as well as PLCs,
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, a
modular system of electronics can be installed directly on the flow 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 blind analog transmitter can be used to convert to a 4-20 mA output. IP meters
are also compatible with the DL76 data logger and FT520 batch processor.
Turbine flow sensors from the TX800 Series require special fittings since they are
not depth-adjustable. Installation in the fitting ensures correct depth placement in the pipe.
Fittings are available in PVC, brass, and stainless steel. Flow sensors are available in brass,
316 stainless steel, and polypropylene. In plastic pipe 3" to 8", use an IP82 sensor, which is
1" longer than the IP81 to accommodate the larger fittings.
