Siemens SITRANS LU 01 User Manual
The SITRANS LU 01 is an ultrasonic level monitoring system from Siemens that measures liquid or solid levels without contacting the material. It uses a Siemens‑Milltronics ultrasonic probe and optional temperature sensor to calculate distance based on echo time.
The instruction manual covers product specifications, installation requirements, electrical characteristics, probe mounting, wiring diagrams, programming via the handheld controller, Dolphin Plus software or SmartLinx, supported communication protocols, and detailed fault‑diagnosis procedures such as the LOE error display. This manual is written in Chinese.
