DESCRIPTION
ONICON inline turbine flow meters are suitable
for measuring electrically conductive water-based liquids. The F-1320 model provides a binary (digital) dry contact output signal corresponding to flow rate, which is divided to meet the monitoring system input frequency limitation.
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
