Principles and advantages of miniature electromagnetic flowmeters
The miniature electromagnetic flowmeter is an inductive instrument that measures the volume flow of the conductive medium in the tube according to Faraday's law of electromagnetic induction. It uses single-chip embedded technology to complete digital excitation. At the same time, the electromagnetic flowmeter uses CAN field bus. The technology has reached the domestic high Level. In addition to measuring the flow of ordinary conductive liquids, it can also measure the volumetric flow of liquid-solid two-phase flow, high-viscosity liquid flow, and salt, strong acid, and strong alkali liquids. It is widely used in chemical, environmental protection, metallurgy, medicine, papermaking, water supply and drainage industries.
Product Features:
1. There are no moving parts in the pipeline, no flow blocking parts, and almost no additional pressure loss during the measurement.
2. The measurement result has nothing to do with the flow rate distribution, fluid pressure, temperature, density, viscosity and other physical parameters.
3. The measuring range can be adjusted online according to the theoretical needs of users on site.
4. High-definition backlight LCD display, full Chinese menu operation, easy to use, simple to operate, easy to learn and understand.
5. Using SMD devices and surface mount (SMT) technology, the circuit has high reliability.
6. It adopts 16-bit embedded microprocessor, fast calculation speed and high precision, programmable frequency low frequency rectangular wave excitation, which improves the stability of flow measurement.
7. Fully digital processing, strong anti-interference ability, reliable measurement, high precision, flow measurement range up to 150:1
8. Ultra-low EM1 switching power supply, suitable for a wide range of power supply voltage, and good anti-EMC performance.
9. With digital communication signal output such as RS485, RS232, Hart and Modbus.
10. It has the functions of self-check and self-conclusion, and provides the function of non-linear correction of the sensor for no reason.
11. Power-off maintenance. The calculation results of the flowmeter and the parameters set by the user will not disappear after the power is off. The EEPROM can maintain the set parameters and accumulated values.
12. The converter and sensor have a variety of protection logout and installation methods, and have an IP68 rating suitable for diving installation.
