LDBE type intelligent electromagnetic flowmeterDetailed product description：

The LDBE intelligent electromagnetic flowmeter is a fully intelligent electromagnetic flowmeter developed using the most advanced technology at home and abroad. Its all Chinese electromagnetic converter core adopts a high-speed central processing unit. The calculation speed is very fast, the accuracy is high, and the measurement performance is reliable. The converter circuit design adopts international advanced technology, with an input impedance of up to 10 ^ 15 ohms, a common mode rejection ratio of better than 100db, and a suppression ability of better than 90db for external interference and 60Hz/50Hz interference. It can measure fluid medium flow rates with lower conductivity. The sensor adopts non-uniform magnetic field technology and a special magnetic circuit structure, which makes the magnetic field stable and reliable, and greatly reduces the volume, reduces repetition, and makes the flowmeter small and flow oriented.
