ONICON insertion turbine ﬂow meters are suitable for measuring electrically conductive water-based liquids. The F-1220 model provides a binary (digital) dry contact output signal corresponding to ﬂow rate, which is divided to meet the monitoring system input frequency limitation.
• Closed loop chilled water, hot water, condenser water & water/glycol/brine solutions for HVAC
• Process water & water mixtures
• Domestic water

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.
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.
