The use of electromagnetic flow meter and the requirements for accuracy

Abstract: The information on the use of electromagnetic flowmeters and the requirements for accuracy are provided by excellent flowmeter and flowmeter manufacturers. The flow sensor converts the volume flow of the conductive liquid flowing through the pipe into a linear electrical signal [3]. The conversion principle is the famous Faraday's law of electromagnetic induction, that is, the conductor passes through the magnetic field, cuts the electromagnetic wire, and generates an electromotive force. Magnetic field of flow sensor. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are the details of the use of electromagnetic flowmeters and the requirements for accuracy. The flow sensor converts the volume flow of the conductive liquid flowing through the pipe into a linear electrical signal [3]. The conversion principle is the famous Faraday's law of electromagnetic induction, that is, the conductor passes through the magnetic field, cuts the electromagnetic wire, and generates an electromotive force. The magnetic field of the flow sensor is realized by excitation, which is divided into DC excitation, AC excitation and low frequency square wave excitation. Most flow sensors now use low frequency square wave excitation. The transmitter is composed of excitation circuit, signal filtering and amplifying circuit, A/D sampling circuit, microprocessor circuit, D/A circuit, transmission circuit, etc. The installation requirements of the electromagnetic flowmeter must be installed at the lowest point of the pipeline or the vertical section of the pipeline, but it must be in the case of full pipelines. usage and accuracy requirements. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
