HKLD intelligent electromagnetic flowmeter is a kind of fully intelligent electromagnetic flowmeter developed by our company with advanced technology at home and abroad. Its Chinese electromagnetic converter core uses high-speed central processing unit. The calculation speed is very fast, the accuracy is high, and the measurement performance is reliable. The circuit design of the converter adopts international advanced technology, the input impedance is up to 10 ohms, the CMRR is better than 100db, and the rejection ability for external interference and 60Hz/50Hz interference is better than 90db. It can measure the flow rate of fluid medium with lower conductivity.
