YW04-SRadar Level Transmitter
FMCW Radar Level Meter with Display
76-81 GHz FMCW radar level meter measures liquid and solid levels with ranges of 15 m, 35 m, 85 m or 120 m by model, ±1 mm accuracy, and 4–20 mA plus RS-485 outputs. It supports HART/MODBUS communication and suits high-dust, high-temperature environments up to +200 °C, with flange or thread mounting. Typical applications include storage tanks, silos, and process vessels.
