LDCK electromagnetic flowmeter is a high-precision, reliable product designed and manufactured by Shanghai Ziyi Jiu Instrument Co., Ltd. It is suitable for measuring the volume flow of conductive media such as acid, alkali, salt solution, mud slurry, paper pulp and wastewater, and there is no additional pressure loss in the measuring tube.
The Ziyi LDCK electromagnetic flow meter is a high‑precision, high‑reliability device for measuring the volumetric flow of conductive liquids such as acids, alkalis, salts, slurries, pulp and wastewater. It is offered in integrated (one‑piece) and split (sensor‑converter separate) configurations, with optional display units showing instantaneous and cumulative flow.
The manual covers the meter’s basic parameters, technical data, installation requirements, grounding, wiring, output signal options, parameter settings, alarm handling, fault troubleshooting, and mechanical dimensions. Appendices provide details on dip‑switch settings and converter dimensions, as well as a user feedback form. This manual is written in Chinese.
