1.1

Designated use

The Prosonic M is a compact measuring device for continuous, non-contact level
measurement. Depending on the sensor, the measuring range is up to 15m in fluids and
up to 7m in bulk solids. By using the linearisation function, the Prosonic M can also be
used for flow measurements in open channels and measuring weirs.
1.2

Installation, commissioning, operation

The Prosonic M 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

Hazardous area

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 supplementary
documentation is mandatory.
• Ensure that all personnel are suitably qualified.
• Observe the specifications in the certificate as well as national and local regulations.
