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.

Ultrasonic flowmeter classification
●Insert ultrasonic flowmeter: can be installed and maintained without stopping production. Ceramic sensors are used for non-stop production installation using dedicated drilling equipment. Generally for mono measurement, in order to improve measurement accuracy, three channels can be selected.
● Pipe-type ultrasonic flowmeter: It is necessary to cut the pipeline installation, but the subsequent maintenance can be stopped. Mono or 3-channel sensors are available.
● External clip-on ultrasonic flowmeter: capable of performing fixed and mobile measurements. It is installed with a special coupling agent (silicone rubber cured at room temperature or high-temperature long-chain polymer grease) and does not damage the pipeline during installation.
● Portable ultrasonic flowmeter: portable, built-in rechargeable lithium battery, suitable for mobile measurement, with magnetic sensor.
1, non-contact measurement method, small size, easy to carry
2, suitable for on-site measurement of various sizes of pipe sound guiding media
3, built-in nickel-metal hydride rechargeable battery working time of more than 20 hours
4, user interface is flexible, easy to use
5, intelligent on-site printing function to ensure the integrity of the flow data
6, equipped with an integrated aluminum alloy protective box, can be used in harsh outdoor environments
● Hand-held ultrasonic flowmeter: small size, light weight, built-in rechargeable lithium battery, hand-held, with magnetic sensor.
● Explosion-proof ultrasonic flowmeter: used for explosive liquid flow measurement, it is explosion-proof and intrinsically safe. That is, the converter is explosion-proof and the sensor is intrinsically safe.
