Intelligent electromagnetic flowmeters (EMF for short) are new flow measurement instruments that developed rapidly with the development of electronic technology in the 1950s and 1960s. The electromagnetic flowmeter is an instrument that applies the principle of electromagnetic induction to measure the flow rate of conductive fluid based on the electromotive force induced when the conductive fluid passes through an external magnetic field.
Features:
1. Measurement is not affected by changes in fluid density, viscosity, temperature, pressure and conductivity;
2. No obstruction to flow in the measuring tube components, no pressure loss, and lower requirements for straight pipe sections. Adaptability to slurry measurement;
3. Reasonable selection of sensor lining and electrode materials, that is, good corrosion resistance and wear resistance;
4. The converter adopts novel excitation method, low power consumption, stable zero point and high accuracy. The flow range can reach 150:1;
5. The converter can be integrated with the sensor or separate;
6. The converter adopts a 16-bit high-performance microprocessor. 2x16LCD display, convenient parameter setting, reliable programming;
7. The flow meter is a bidirectional measurement system with three built-in totalizers: forward total, reverse total and difference total; it can Displays forward and reverse flow, and has a variety of outputs: current, pulse, digital communication, HART;
8. The converter adopts surface mounting technology (SMT) and has self-test and self-diagnosis functions;
9. The measurement is not affected by changes in fluid density, viscosity, temperature, pressure and conductivity. The sensor induced voltage signal has a linear relationship with the average flow rate, so the measurement is high;
10. Measurement There are no flow-blocking parts in the pipeline, so there is no additional pressure loss; there are no moving parts in the measuring pipeline, so the sensor has a very long life; 11. Since the induced voltage signal is formed in the entire space filled with magnetic fields, it is on the surface of the pipeline average value, so the straight pipe section required by the sensor is shorter and the length is 5 times the pipe diameter;
12. The converter adopts international microcontroller (MCU) and surface mount technology (SMT), with reliable performance , high, low power consumption, stable zero point, and convenient parameter setting. Click the Chinese to display the LCD to display cumulative flow, instantaneous flow, flow rate, flow percentage, etc.;
13. Bidirectional measurement system, which can measure forward flow and reverse flow. Special production processes and high-quality materials are used to ensure that the product's performance remains stable over a long period of time.
