1.1 Designated use
The Prosonic S FMU95 is a transmitter for up to 10 ultrasonic sensors FDU90, FDU91, FDU91F,
FDU92, FDU93, FDU95 and FDU96. The sensors of the class FDU8x can be connected as well.
Functions:
• display of up to 10 measuring values
• interference echo suppression for each connected sensor
• linearistaion for each sensor individually programmable
• configurable calculation of sums and average values
• measuring value transmission via PROFIBUS DP
1.2 Installation, commissioning, operation
The Prosonic S FMU95 is fail-safe and 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.
The transmitter may only be installed in suitable areas. Sensors with a certificate for hazardous areas
may be connected to a transmitter without a certificate.

The sensors FDU83, FDU84, FDU85 and FDU86 with an ATEX, FM or CSA certificate are not
certified for connection to the FMU90 transmitter.
