FB-1200 Insertion Turbine Flow Meter

FB-1200 Series

FB-1200 Series Bi-directional Dual Turbine Flow Meters are suitable for pipe sizes ranging from 2½" to 72". Bi-directional dual turbine meters accurately measure flow in both directions and provide an isolated contact closure output to indicate flow direction.

Typical Applications
ONICON FB-1200 Series Bi-directional Insertion flow meters are designed to work in pipe sizes ranging from 2½" to 72" in diameter.

The FB-1200 Series Bi-directional Flow Meters, with their built-in flow direction switch, are ideal for primary / secondary decoupled (bypass) loops, stratified thermal storage tanks and municipal water storage tank charge / discharge lines.

Standard Features

Highly Accurate
NIST traceable factory calibration performed on every flow meter, within ±0.5% of reading accuracy at the calibrated (typical) flow velocity and within ±1-2% of reading over a 50:1 flow range. ONICON's price vs. performance is unmatched.

Unequaled Operating Range
Provides repeatable flow data over a 175:1 turndown from 0.17 to 30 ft/s.

Excellent Long-Term Reliability
Patented non-magnetic impedance sensing method, low mass non-metallic turbines with sapphire jewel bearings and tungsten carbide shafts provide a mechanical system that virtually does not wear.

Simplified Hot Tap Insertion Design
Integral hot-tap design is standard for all insertion meters and allows installation and removal without system shutdown. Turbine meters can be removed and reinserted by hand without special tools.

Integral Conditioned Outputs
Electronics enclosure includes integral conditioned output circuitry for ease of installation. Analog output models include both 4-20 mA and 0-10 VDC signals. Isolated-analog, dry contact switch and frequency outputs are also available.
