Advantages of plug-in electromagnetic flowmeter

by:Sure     2020-07-02
 Plug-in electromagnetic flowmeter is composed of sensor and converter. It is based on Faraday's law of electromagnetic induction. It is used to measure the volume flow of conductive liquid with conductivity greater than 5μS/cm. It is an inductive instrument that measures the volume flow of conductive medium. In addition to measuring the volume flow rate of general conductive liquids, it can also be used to measure the volume flow rate of strong corrosive liquids such as strong acids and bases and uniform liquid-solid two-phase suspended liquids such as mud, ore pulp and paper pulp. It is widely used in the flow measurement of industrial sectors such as petroleum, chemical industry, metallurgy, textile, papermaking, environmental protection, food and municipal management, water conservancy construction, river dredging and other fields. Electromagnetic flowmeter product features: 1. The instrument has simple and reliable structure, no moving parts and long working life. 2. There are no blocking and blocking parts, and there is no pressure loss and fluid blockage. 3. No mechanical inertia, fast response and good stability, can be applied to automatic detection and adjustment program control system. 4. The measurement accuracy is not affected by the type of measured medium and its physical quantity parameters such as temperature, viscosity and pressure. 5. The seal designed separately at the connection between the sensor and the meter head can prevent external moisture from entering the meter head and the sensor from the connection point. 6. Both the excitation line and the electrode line use high-quality single-core shielded wire, which can reduce interference and improve the cleanliness of the signal, thereby improving the measurement accuracy. 7. The surface paint of the sensor is made of metal fluorocarbon paint. The fluorocarbon bond of the fluorocarbon resin molecules in the metal fluorocarbon paint can resist the degradation of ultraviolet rays, showing extremely excellent durability, UV resistance and weather resistance, making the metal fluorine The carbon paint coating is perfect for a long time, reducing maintenance requirements. 8. With two-way flow measurement, two-way total accumulation function, there are three internal totalizers can display the forward cumulative value, reverse cumulative value and difference cumulative amount. 9. Frequency programmable low-frequency three-value wave excitation, which improves the stability of flow measurement and low power loss. 10. The new 32-bit ARM+CPLD has high integration, fast calculation speed and high calculation accuracy. 11. Full digital processing, strong anti-interference ability, reliable measurement. 12. Ultra-low EMI switching power supply, suitable for wide range of power supply voltage, high efficiency, small temperature rise, good EMC performance. 13. Chinese and English menu operation, easy to use, simple operation, easy to learn and understand. 14. High definition wide temperature OLED display. 15. Using intelligent judgment, without using measurement correction settings, the application of empty pipe alarm and electrode detection is more convenient. 16. The advanced 'coarse error processing' technology can cut off the sharp interference of the fluid measurement such as slurry, reduce the output jitter, maintain 18. High-precision measurement and make the output more stable. 17. With self-test and self-diagnosis function. 18. New keyboard processing method to avoid keyboard operation affecting measurement. You can enter and retreat the operating menu to make parameter setting more convenient. 19. The AD421 current dedicated chip makes the 4-20mA current output more stable.
