Product features of Electromagnetic flowmeter

★ The measuring tube contains no moving parts, facilitating maintenance and management. No flow obstructing components ensure zero pressure loss.
★ Measurable liquids require a minimum conductivity of ≥5 μs/cm. Compatible with various lining materials, suitable for measuring flows in acids, alkalis, salt solutions, slurries, mineral slurries, and paper pulp.
★ Flow measurement remains unaffected by fluid density, viscosity, temperature, pressure, or conductivity variations. Sensor voltage signals demonstrate a linear relationship with average flow velocity, ensuring high measurement accuracy.
★ Proper selection of lining and electrode materials achieves excellent corrosion resistance and wear resistance.
★ Low-frequency rectangular wave excitation eliminates interference from power frequency and field noise, ensuring stable operation.
★ Accurate measurement applies to both forward and reverse flow directions.
★ Wide range ratio (1.120(0.1m/s-12m/s), broad full-range flow velocity measurement.
★ Chinese LCD backlight display allows online parameter modification with intuitive operation.
★ Features empty tube measurement and alarm functions adaptable to diverse fluid media.
★ Power outage duration recording automatically logs system power interruptions and recalculate missed flow data.
★ Hourly total volume recording monitors hourly flow totals, compatible with time-based metering systems.
