1. Range of intelligent electromagnetic flowmeter
The measurement range of intelligent electromagnetic flowmeter is usually recommended to have a flow rate of 2 to 4 meters/second in industrial applications, but in special cases, the minimum flow rate should not be less than 0.2 meters/second and the maximum should not exceed 8 meters/second. For media containing solid particles, it is recommended to have a flow rate of less than 3 meters per second to reduce electrode wear. For viscous fluids, a higher flow rate (greater than 2 meters/second) helps to automatically remove attachments and improve measurement accuracy. Under the condition of known flow rate Q, the diameter D (inner diameter of the pipeline) of the flowmeter can be determined by the following formula: Q=π D ² V/4, where Q represents flow rate (m ³/h) and V is flow velocity (m/h). The range of the flowmeter should be greater than the expected maximum flow value, and the conventional flow rapid closing should be slightly greater than 50% of the full scale scale. The following are flow meters of different diameters, corresponding to their respective flow ranges: φ15: 0.06~6.36 m³/hφ20: 0.11~11.3 m³/h...φ300: 25.43~2543.40 m³/hφ400: 45.22~4521.6 m³/h... The selection of flowmeter models includes different materials (such as 316L, HB, HC, etc.) and lining materials (such as polytetrafluoroethylene F
4, perfluoroalkoxy F46, etc.). In terms of functionality, there are different accuracy levels (0.
3, 0.
5, 1), load capacity, output frequency, interface type (such as RS485 interface), temperature adaptability (normal temperature, high temperature, ultra-high temperature), and pressure level (1.0MPa to 16MPa) to choose from. Structurall

2. What are the properties of electromagnetic flow meters?
A new type of flow measurement instrument that has rapidly developed with the development of electronic technology.
. An electromagnetic flowmeter is an instrument that uses Faradays principle of electromagnetic induction to measure the flow rate of a conductive fluid based on the induced electromotive force when the fluid passes through an external magnetic field.1、 Measurement is not affected by changes in fluid density, viscosity, temperature, pressure, and conductivity;
2、 There are no obstructing flow components or pressure loss inside the measuring tube, and the requirements for straight pipe sections are relatively low. Has unique adaptability to slurry measurement;
3、 Reasonably selecting sensor lining and electrode materials, which have good corrosion resistance and wear resistance;
4、 The converter adopts a novel excitation method, with low power consumption, stable zero point, and high accuracy. The flow range can reach 150:1;
5、 The converter can be integrated or separated from the sensor;
6、 The converter adopts a 16 bit high-performance microprocessor, 2x16 LCD display, convenient parameter setting, and reliable programming;
7、 The flowmeter is a bidirectional measurement system equip
