Specifications General Information
The TX80 Series are turbine-type insertion meters de-
signed for use in pipe sizes 1" to 8". High-quality jewel
bearings and nickel-bound tungsten carbide shaft are
used for maximum life and extreme low friction. Bodies
are machined from solid rod for maximum precision. Low-
flow performance is superior. The rotation of the rotor is
detected by a non-drag Hall-effect sensor. Output is a
pulse-type square wave, which can be sent long dis-
tances (up to 2,000 feet) without a transmitter. This sig-
nal can be connected directly to SeaMetrics controls, as
well as PLC's, counters, and computer cards.
SeaMetrics TX80 meters are ideal for chemical propor-
tioning applications. If no display is required, a simple
divider such as the PD10 provides adjustable pump pac-
ing. For rate and total display, as well as pump pacing,
the FT420 flow indicator can be mounted directly on the
TX80 Series, or remotely on a wall or panel.
The TX80 Series require special fittings, since they are
not depth-adjustable, installation in the fitting ensures
correct depth placement in the pipe. Fittings are avail-
able in PVC, brass, and stainless steel. Sensors are avail-
able in brass, 316 stainless steel, and polypropylene. In
plastic pipe 3"-8", use an IP82 sensor, which is 1.00"
longer than the IP81 to accommodate the larger fittings.
