DESCRIPTION

ONICON insertion turbine flow meters are suitable for measuring electrically conductive water-based liquids. The F-1230 model provides a scaled binary (digital) dry contact output signal where each pulse equals a specific unit volume - an ideal choice for totalized flow applications.

APPLICATIONS

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

• Process water & water mixtures

• Domestic water

GENERAL SPECIFICATIONS

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.

Simplified Hot Tap Insertion Design -
Standard on every insertion flow meter. Allows for insertion and removal by hand without system shutdown.
