Instrument Control Flowmeter Manufacturers Introduce Leading Technologies from Foreign Countries - Focus on Microfluidic Control Technology

With the development of electronics and computer skills, the development of flowmeter electromagnetic flowmeters has been accelerated. The change in flowmeter manufacturers is mainly due to the metal measurement tubes and conductive liquids in alternating magnetic fields, even if the fluid flow rate is zero. Under the circumstances, due to the effect of electromagnetic induction, eddy currents will still occur, resulting in secondary magnetic fluxes. Low-frequency rectangular wave excitation can effectively reduce the occurrence of secondary magnetic flux, so the zero point is more stable.

The electromagnetic flowmeter at that time could complete the miniaturization of goods. The integrated structure of the sensor and the converter can effectively reduce the manufacturing cost of the flow meter. Electromagnetic flowmeters that communicated in the early stages of excitation have large eddy current losses. In order to obtain high measurement accuracy, a strong induced electromotive force is required. At this time, the planned magnetic field of the sensor is approximately 1 to 2 mV of induced signal voltage at the flow rate Im/s. Therefore, the communication excitation electromagnetic flowmeter usually consumes several tens to several kW. The low-frequency rectangular wave magnetic field is in the direct current condition most of the time, and its core eddy current loss is very small, and the magnetic induction intensity is very low. The sensor magnetic field planned in this way is approximately 0.l~0.2mV inductive signal voltage at an Im/s flow rate. Improve the company's bottom line automation and leading control level to enhance the company's market competitiveness.

The use of a new type of automatic detection and analyzer: The development of digital, intelligent, networked, and miniaturized external and external appearance systems has enabled petrochemical companies to increase the level of automatic detection of appearance. Field bus type transmitters have been rapidly developed to meet the requirements of fieldbus control systems. The transmitter is all digital, simple in construction, and has higher resolution and stability than general smart transmitters. Due to the fact that fieldbus digital appearance products are becoming more and more perfect, and they are highly reliable and interoperable, they will have different features such as integrated configuration of brand goods, and will be used more in the field of petrochemical process control.
