1.1 Designated use
The Prosonic T is a compact measuring device for continuous, non-contact level measurement.
Depending on the sensor, the measuring range is up to 8 m (26 ft) in fluids and up to 3.5m (11 ft)
in bulk solids.
1.2 Installation, commissioning, operation
The instrument is fail-safe and is constructed to the state-of-the-art. It meets the appropriate
standards and EC directives. However, if you use it improperly or other than for its designated use,
it may pose application-specific hazards, e.g. product overflow due to incorrect installation or
configuration. Installation, electrical connection, start-up, operation and maintenance of the
measuring device must therefore be carried out exclusively by trained specialists authorised by the
system operator. Technical personnel must have read and understood these operating instructions
and must adhere to them. You may only undertake modifications or repair work to the device when
it is expressly permitted by the operating instructions.
1.3 Operational safety and process safety
Alternative monitoring measures must be taken to ensure operational safety and process safety
during configuration, testing and maintenance work on the device.
Hazardous areas
Measuring systems for use in hazardous environments are accompanied by separate "Ex
documentation", which is an integral part of this Operating Manual. Strict compliance with the
installation instructions and ratings as stated in this Additional documentation is mandatory.
• Ensure that all personnel are suitably qualified.
• Observe the specifications in the certificate as well as national and local regulations.
