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.
