LDB electromagnetic flowmeter

LDB electromagnetic flowmeterIt mainly consists of two parts: sensors and converters. The sensors include flanges, liners, electrodes, measuring tubes, excitation coils, sensor housings, and other parts; The converter includes internal circuit board and converter housing.
1. Converter: Provides stable excitation current for sensors, amplifies and converts the induced electromotive force obtained through sensors into standard electrical signals, and displays real-time flow and parameters for flow display, control, and regulation.
2. Lining: A complete layer of electrically insulating and corrosion-resistant material on the inner side of the measuring tube and the sealing surface of the flange.
3. Electrode: A pair of electrodes are installed on the measuring tube wall to detect flow signals, and 1-2 grounding electrodes are also installed for grounding and anti-interference of flow signal measurement.
