2. Preliminary Selection (1) the name and nature of the measured media learned split electromagnetic flowmeter price, to determine whether the use of electromagnetic flowmeters (determined by the clerk) Note: Electromagnetic flowmeters only measure electromagnetic conductive liquid flow split meter pictures, but not in cases of conductive liquids in general gas, oil, and the vast majority of organic liquids (2) understand the nature of the medium is to determine the electrode material note; companies generally provide stainless steel, Hastelloy, titanium and tantalum four kinds of electrode, which electrode selection should check the relevant information booklet 3. electrochemical polarization potential interference based on media properties. Electrochemical polarization potential interference is due to differences in bipolar electrode polarity induced electromotive force caused by electrolyte polarization generated on the electrode surface. Although the use of positive-negative alternating excitation magnetic field can significantly weaken the polarization potential of the order of magnitude, but not essentially completely eliminate polarization potential interference. Its properties on the nature of the fluid medium, the nature of the electrode material, dimensions about the shape of the main electrode split electromagnetic flowmeter, with changes slowly, and other characteristics of magnitude less fluid electrochemical potential interference and their solutions. So choose a suitable electrode material (such as tungsten carbide), to design the best shape of the electrodes is an effective way to reduce the size of the polarization potential; other uses alternating positive and negative poles of the rectangular wave excitation synchronous technology with microprocessor wide pulse sampling technique to use microprocessor computing functions sampled twice before subtracting eliminate traffic signal potential of polarization potential interference. Split electromagnetic flowmeter sales force measuring instrument since, Jilin split 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.
