Turbine Flow Meters - Inline

F-1300 Series
F-1300 Series Inline Turbine Flow Meters are available with copper sweat or NPT process connections for pipe sizes of ¾" and 1". Inline flow meters provide an effective low cost option for measuring flow in small pipes.

Typical Applications
ONICON F-1300 Series Inline Flow Meters are designed to work in pipes of ¾" and 1" in diameter. The F-1300 series flow meters deliver highly accurate flow data when installed with enough straight pipe run to establish a fully developed flow profile.

Typical uses for the F-1300 series meters include: chilled water, hot water, condenser water, process cooling 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 ±2% of reading over a 50:1 flow range. ONICON's price vs. performance ratio is unparalleled.

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.

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.
