This manual provides installation methods, wiring details, and usage guidelines for the Ningbo Keli NHS weighing module.
The NHS weighing module offers several installation options—radial, tangential, and rectangular—and includes safety features such as anti‑tilt devices and grounding. The manual outlines functional features and the steps required to mount the sensor correctly, including base preparation and level adjustments.
Three soft‑connection types are described for linking the container to pipelines: flexible hose, U‑shaped hose, bellows, and sleeve connections. The appropriate connection is chosen based on the chemical nature of the conveyed material, with specific diagrams for non‑volatile and volatile liquids. Cable color coding and troubleshooting tips are also provided. This manual is written in Chinese.
