Seametrics TB - Manual

TB Turbine Flow Meter
Instructions
The TB are bronze-bodied turbine meters designed for
use in pipe sizes 1-1/2" to 4". High-quality jewel bear-
ings and ceramic shafts are used in the standard ver-
sion. 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 distances (up to 2,000 feet) without a transmitter.
This signal can be connected directly to SeaMetrics con-
trols, as well as PLC's, counters, and computer cards.
Battery operation using the FT415 battery-operated Flow
Computer is also available as an option (requires micro-
power sensor).
SeaMetrics TB Turbine Meters are ideal for chemical pro-
portioning 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 FT415/420 flow indicator can be mounted directly
on the TX80 Series, or remotely on a wall or panel.
The TB consists of a brass machined insert and a cast
bronze flow tube. The rotor, sensor, and all replaceable
parts are removable by pulling a simple u-clip lock.
