Turbine Water Flow Meter TX Series

Turbine Water Flow Meter X100/200-Series are adjustable depth insertion turbines that come in brass or 316 stainless models to fit 3” to 40” pipe. Adapters mate with standard 1-1/2” (11x/21x) or 2” (15x/25x) FNPT threaded fittings such as saddles and wallets which may be purchased either locally or from Seametrics.

Ruby bearings and a non-drag pickoff give these adjustable insertion turbine flow sensors a wide flow range and long life. A sensor detects the passage of miniature magnets in the rotor blades. The resulting square-wave signal can be sent for hundreds of feet without a transmitter, over an unshielded cable. This signal can be connected directly to many PLCs and other controls without any additional electronics.

A modular system of electronics can be installed directly on the flow sensor or mounted remotely. The FT430 (externally powered with a 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 is a blind analog (4-20 mA) transmitter. A programmable pulse for pump pacing is available with the PD10.

Features

• Wide flow range
• One moving part
• Hot tap available
• Modular electronics compatible
• Easily depth adjustable for 3-40” pipe

Applications

• Clean water
• Large pipes
• Aquariums, water parks
• Water & wastewater monitoring

The “hot-tap” models (TX15x/25x) can be installed or serviced without shutting down the line by means of a 2” full-port isolation valve that comes with a nipple for installation on the pipe fitting. In most circumstances, no special tool is required.
