DESCRIPTION

ONICON inline turbine flow meters are suitable for measuring electrically conductive water-based liquids. The F-1311 model provides isolated
4-20 mA and 0-10 V analog output signals that are linear with the flow rate.

CALIBRATION

Every ONICON flow meter is wet calibrated in our flow laboratory against primary volumetric standards that are directly traceable to N.I.S.T. A certificate of calibration accompanies every meter.

FEATURES

Unmatched Price vs. Performance - Custom calibrated, highly accurate instrumentation at very competitive prices.

Excellent Long-term Reliability - Patented electronic sensing is resistant to scale and particulate matter. Low mass turbines with

engineered jewel bearing systems provide a mechanical system that virtually does not wear.

Industry Leading Two-year “No-fault” Warranty

Reduces start-up costs with extended coverage to include accidental

installation damage (miswiring, etc.) Certain exclusions apply. See our complete warranty statement for details.

APPLICATIONS

• Closed loop chilled water, hot water, condenser water & water/glycol/brine solutions for HVAC

• Process water & water mixtures
