Use and promotion of electromagnetic flowmeter
The intelligent electromagnetic flowmeter is a fully intelligent electromagnetic flowmeter developed by our company using advanced technology at home and abroad. Its all-Chinese electromagnetic converter core adopts high-speed central processing unit, which has fast calculation speed, high precision and reliable measurement performance. The converter circuit design adopts the latest international technology, the input impedance is up to 1015 ohms, the common mode rejection ratio is better than 100db, and the external interference and 60Hz/50Hz interference suppression ability is better than 90db, which can measure the lower conductivity fluid medium flow. The sensor adopts a new non-uniform magnetic field technology and a special magnetic circuit structure. The magnetic field is stable and reliable, and the volume is greatly reduced, the weight is reduced, and the flowmeter has the characteristics of small size and light weight. Adhering to the enterprise spirit of "seeking truth, hard work, innovation and development", we insist on "customer first, technology first, high quality, first-class service", we will provide you with first-class products and first-class service.
