This manual introduces the features and characteristics of the ultrasonic liquid level meter SITRANS LU 01, including programmable features, electronic components, programmers, transducers, options, cables, installation, system diagrams, etc.
The SITRANS LU 01 is an ultrasonic long‑range level monitoring system for liquids and solids. It uses a Siemens Milltronics ultrasonic transducer to emit pulses and measure the echo return time, converting this to a distance, level, space or volume reading displayed on a back‑lit LCD.
The manual provides detailed information on features, electrical specifications, installation requirements, programming via the portable keypad or Dolphin Plus/SmartLinx software, communication options, and extensive troubleshooting guidance to ensure reliable operation in industrial environments. This manual is written in Chinese.
