ONICON inline turbine ﬂow meters are suitable
for measuring electrically conductive water-based liquids. The F-1330 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.
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.
