The Smart Electromagnet Voltex flowmeter is a new generation of Voltex flowmeter developed by applying the Karman vortex principle and Faraday electromagnetic induction principle by detection technique. signal with unique sensor structure and integrating sensor and signal detection techniques and other new advanced techniques Due to its simple structure, no moving parts and small pressure loss, the signal The flow is unaffected by the density, temperature, viscosity and the composition of the medium over a certain Reynolds number range and the flow measurement range is wide and the vibration resistance is good. High precision, powered by lithium batteries, convenient installation, long term use without maintenance, etc., can measure the flow rate of different conductive fluids and can be widely used in fire fighting, petroleum, chemicals, printing and dyeing, leather, medicine, food, environmental protection, municipal water supply and drainage, etc. Industry flow measurement.
