FEATURES
The TX800-Series are insertion turbine meters designed for
use in 1-1/2" to 8" pipe. High-quality jewel bearings and preci-
sion shafts ensure long life and low friction. Available in 316
stainless steel, brass and PVC, sensor bodies are machined
from solid rod for maximum low-flow performance. The TX800-
Series use special fittings that ensure ease of installation and
correct depth setting in the pipe.
The rotation of the turbine is detected by a non-drag Hall-effect
sensor. Output is 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 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, the FT420 flow indica-
tor can be mounted directly on the TX800-Series, or remotely
on a wall or panel. The FT415 offers a battery-operated rate/
totalizer where power is not available.
Caution: U-clip
must be installed
before use.
