This manual is an instruction manual for the use and precautions of the product.
The NWR-2W is a float‑type water level indication transmitter designed for dams, reservoirs and similar applications. It detects water level by the vertical movement of a float and converts it to a 4‑20 mA current signal.
The sheet lists the device’s construction, material options, electrical characteristics, measurement range, accuracy and optional alarm contacts, providing the data needed for selection and installation. This manual is written in Japanese.
