ONICON Incorporated’s F-3500 series insertion electromagnetic ﬂow meters are suitable for measuring electrically conductive liquids in a wide variety of applications. Each F-3500 provides a single analog output for ﬂow rate, a high resolution frequency output to drive peripheral devices, a scalable pulse output for totalization and an empty pipe alarm signal. Optional remote displays and Btu measurement systems are also available.
Exceptional Performance & Value - F-3500 series insertion style electromagnetic ﬂow meters provide a degree of accuracy and reliability normally only found in expensive full bore devices. By combining this level of performance with the cost effective nature of the insertion style design, ONICON has produced a product of exceptional value.
Excellent Long Term Reliability - ONICON insertion style electromagnetic ﬂow meters employ a low maintenance, non-moving parts technology to sense ﬂow. State-of-the-art electronics and patented design features help maintain accuracy over time.
Proprietary Design Advantage - F-3500 insertion electromagnetic ﬂow meters utilize patented design features that signiﬁcantly enhance performance. The dual-electrode design and continuous auto-zero function combine to improve accuracy and sensitivity — particularly at low ﬂow rates.
Simpliﬁed Hot Tap Insertion Design -
Standard on every insertion ﬂow meter, this feature allows for insertion and removal by hand, without a system shutdown.
• Chilled water, hot water, condenser water & water/glycol solutions for HVAC
• Process water & water mixtures
• Domestic/municipal water
Every ONICON ﬂow meter is wet calibrated
in a ﬂow laboratory against standards that are directly traceable to N.I.S.T. A certiﬁcate of calibration accompanies every meter.
