HR7100 Electromagnetic Flowmeter
The HR7100 is a fully intelligent electromagnetic flowmeter developed by our company. Its electromagnetic converter core employs a high-speed central processor, ensuring fast calculation speeds, high accuracy, and reliable measurement performance. The converter's circuit design adopts international advanced technology, featuring an input impedance of up to 10 ohms and a common-mode rejection ratio better than 100dB. It demonstrates superior interference suppression capabilities against external interference and 60Hz/50Hz interference, with a rejection ratio better than 90dB, allowing it to measure the flow of low-conductivity fluid media. The sensor utilizes non-uniform magnetic field technology and a special magnetic circuit structure, resulting in a stable and reliable magnetic field, while also reducing size and weight.
