F-1100 Insertion Turbine

F-1100 Series
Turbine flow meters are suitable for pipe sizes ranging from 1¼" to 72" (1" for copper). The single turbine flow meters are ideal for smaller pipes and for larger pipes with enough straight pipe to provide fully conditioned flow.

Typical Applications
ONICON F-1100 Series Insertion Flow Meters are designed to work in pipe sizes ranging from 1¼" to 72" in diameter (1" for copper). The F-1100 Series Turbine Flow Meters deliver highly accurate flow data when used in applications with a straight pipe run long enough to establish a fully developed flow profile.

Typical uses for the F-1100 series turbine flow meters include: chilled water, hot water, condenser water, domestic water, process cooling, steam condensate and brine.

Standard Features:

Highly Accurate
NIST traceable factory calibration performed on every 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 flow 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.
