This manual explains how to install the EMA Intelligence flow sensor, including proper placement in horizontal pipelines, insertion depth of 12 mm, and minimum pipe diameter requirements. It also details wiring connections, terminal diagrams, and the correct use of adapters and nuts.
The document covers menu navigation, LED indicator functions, parameter settings such as high/low flow thresholds, normally open/closed output behavior, keyboard lock/unlock procedures, and factory reset steps. Technical specifications for liquid and gas media, power supply, protection rating, and sensor probe material are also provided. This manual is written in Chinese.
