Integral electromagnetic flowmeter is based on Faraday's law of electromagnetic induction developed to measure the volume flow of conductive fluid. Due to the unique characteristics have been widely used to measure a variety of conductive liquids industry. Mainly used in chemical, paper, food, textile, metallurgy, environmental protection, water supply and drainage and other industries, and computer matching system control can be achieved. Electromagnetic flowmeter inlet section must be straight, straight pipe length must be 10 times the diameter of the pipe, the outlet must also have five times the diameter of the straight section of pipe. By the time the gravimetric method for calibration. When the exhaust end of the price of smart electromagnetic flowmeter, flow tube is relatively stable. Start time intelligent electromagnetic flowmeter sales, timing 30s. Off valve, said liquid weight. Multiple measurements to calibrate the flow of the liquid level. By adjusting the final after a reverse divider output after amplification magnification circuit. So that the output value is consistent with the measured data, the calibration is completed. In this paper, weighing sensor accuracy of 0.05%, to meet the measurement requirements. Due to limitations of the actual conditions, if the measurement time is a bit longer but also can improve the measurement accuracy. Intelligent electromagnetic flowmeter distribution, power measuring instruments since electromagnetic flowmeter, intelligent electromagnetic flowmeter measurements provided by the Shanghai Automation Instrumentation Co., Ltd .. Shanghai Automation Instrumentation Co., force measurement (www.licesh.com) is the Shanghai Zhabei District, flow meters leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Since the force measuring device leadership with the staff warmly welcome all inquiries negotiations to create the force measuring instrument since a better future.
