800EMR Series flowmeters have been engineered to provide accurate interference-free flow measurement in environments affected by high levels of electromagnetic interference (EMI). As modern industrial facilities and critical infrastructure systems become increasingly powered by high-frequency electronics, including variable frequency drives, RF power supplies, converters, and high-voltage equipment, EMI has become a growing threat to measurement stability. Standard flowmeters operating in these environments may experience unstable readings, communication errors, or data. The 8000EMR Series is designed specifically to address these challenges, delivering consistent performance where electromagnetic noise is unavoidable. The 8000EMR Series also meets the IEC 61000-4-3 electromagnetic interference standard, offering exceptional resistance to radiated EMI in harsh electronic environments. Key design features include: Full metal shielding that acts as a Faraday barrier against radiated emissions; Isolated grounds and power circuits to prevent conducted noise and current loops; Differential signal paths to reject common mode interference; Digital filtering and conditioning to remove spikes while preserving response time; and low-emission internal electronics to minimize electromagnetic footprint. These enable the 8000EMR Series to maintain stable, accurate flow measurement without calibration drift, even near high-power electronic equipment. The flowmeters are also designed for robustness in harsh manufacturing environments, with NEMA 4X / IP66 stainless steel construction for wet and industrial conditions; Shock and vibration resistance; Operating liquid temperature ranges from –40 to 90 C; Accuracy of ±3% of full flow range; and Compatibility with many advanced heat-transfer fluids. These capabilities make the 8000EMR Series ideal for mission-critical flow monitoring for semiconductor manufacturing, industrial automation systems, laboratory equipment and data center thermal management. — Proteus Industries, Mountain View, Calif.
