Abstract: The information on the working principle of the split electromagnetic flowmeter is provided by the excellent flowmeter and flowmeter manufacturers. Working principle The measurement principle of the split electromagnetic flowmeter is based on Faraday's law of electromagnetic induction. The split electromagnetic flowmeter consists of a sensor and a converter. The sensor is installed on the measuring pipe, and the converter is installed in the field within 30 meters or 100 meters from the sensor. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following is the details of the article on the working principle of the split electromagnetic flowmeter. Working principle The measurement principle of the split electromagnetic flowmeter is based on Faraday's law of electromagnetic induction. The split electromagnetic flowmeter consists of a sensor and a converter. The sensor is installed on the measuring pipe, and the converter is installed within 30 meters or 100 meters from the sensor. The two are connected by a shielded cable. The main components of the split electromagnetic flowmeter sensor are: measuring tube, electrode, excitation coil, iron core and yoke shell. Mainly used to measure the volume flow of conductive liquids and slurries in closed pipes. Such as water, sewage, mud, pulp, various acids, alkalis, salt solutions, food slurries, etc., widely used in petroleum, chemical, metallurgy, textile, food, pharmaceutical, paper and other industries as well as environmental protection, municipal management, water conservancy construction and other fields of measurement High temperature, high humidity, and inconvenient observation environment. Product Features The split-type electromagnetic flowmeter has full digital processing, strong anti-interference ability, reliable measurement, high precision, flow measurement range up to 150:1 ultra-low EMI switching power supply, suitable for a large range of power supply voltage changes, and good anti-EMI performance. Adopt 16-bit embedded microprocessor, fast operation speed, high precision, programmable frequency low-frequency rectangular wave excitation, which improves the stability of flow measurement and low power consumption. Using SMD devices and surface mount (SMT) technology, the circuit reliability is high. There are no moving parts in the pipeline, no flow blocking parts, and there is almost no additional pressure loss in the measurement. In the field, the range can be modified online according to the actual needs of users. The measurement results are independent of physical parameters such as flow velocity distribution, fluid pressure, temperature, density, and viscosity. High-definition backlit LCD display, full Chinese menu operation, easy to use, simple to operate, easy to learn and understand. It has digital communication signal output such as RS485, RS232, Hart and Modbus. (Optional) It has the functions of self-test and self-diagnosis. Hourly total recording function, recording the total flow in units of hours, suitable for time-sharing metering system (optional) There are three totalizers inside to display the forward cumulative amount, reverse cumulative amount and difference cumulative amount respectively. , there is no power-down always inside, and it can record 16 power-down times. (Optional) Infrared handheld operator, 115KHZ communication rate, long-distance non-contact operation of all functions of the converter (optional). The above is about the working principle and characteristics of the split electromagnetic flowmeter. I hope it will be helpful to you after reading. If you have other electromagnetic flowmeter questions and want to consult, the above is the whole content of this article. You are welcome to inquire about the flowmeter selection of our factory. , quotation, etc. 'Working Principle of Split Electromagnetic Flow Meter'
