The VE11 Series is VNERʼs high-accuracy, full-bore electromagnetic flowmeter (magmeter) for conductive liquids and slurries.
Based on Faradayʼs law of electromagnetic induction, VE11 generates a magnetic field across the measuring tube; as the conductive medium passes through, an induced voltage proportional to flow velocity is detected by electrodes and converted into volumetric flow.
With no moving parts and an unobstructed measuring bore, VE11 delivers long-term stable performance that is largely independent of pressure, temperature, density and viscosity, making it ideally suited for critical process and utility measurement in water, wastewater, chemical, energy and general industrial applications.
