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.
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.
