Prosonic S FMU90 HART Basic safety instructions
Endress+Hauser 7
2 Basic safety instructions
2.1 Designated use
Prosonic S FMU90 is a transmitter for ultrasonic sensors FDU90, FDU91, FDU91F, FDU92,
FDU93 and FDU95. To support existing installations, the following sensors can also be
connected: FDU80, FDU80F, FDU81, FDU81F, FDU82, FDU83, FDU84, FDU85, FDU86,
FDU96.
Typical measuring tasks
• Flow measurement in open flumes and measuring weirs
• (Non-resettable) totalizers and (resettable) daily counters
• Control of samplers by time-based or volume-based pulses
• Detection of backwater and dirt in flumes
• Simultaneous measurement of basin level and discharge volume in a stormwater
overflow basin with just one sensor
2.2 Installation, commissioning and operation
This device has been safely built with state-of-the-art technology and meets the applicable
requirements and EU Directives. However, if it is used improperly or for applications for
which it is not intended, application-related hazards may arise, e.g. product overflow due
to incorrect installation or configuration. Installation, electrical connection,
commissioning, operation and maintenance of the measuring system must therefore be
carried out exclusively by trained specialists authorized to perform such work by the
system operator. Technical personnel must have read and understood these Operating
Instructions and must adhere to them. Modifications and repairs to the device may only be
carried out if they are expressly permitted in the Operating Instructions.
2.3 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.
2.3.1 Hazardous area
When using the measuring system in hazardous areas, the applicable national standards
must be observed. The device is accompanied by separate "Ex documentation", which is an
integral part of these Operating Instructions. The installation specifications, connection
values and safety instructions listed in this supplementary documentation must be
observed.
• Ensure that the technical personnel is sufficiently trained.
• Comply with the metrological and safety-related requirements for the measuring point.
The transmitter may only be mounted in suitable areas. Sensors with an approval for
hazardous areas may be connected to transmitters that do not have an Ex approval.
LWARNING
Explosion Hazard
‣Do not connect FDU83, FDU84, FDU85 and FDU86 sensors with an ATEX, FM, or CSA
certificate to the Prosonic S transmitter.

5.6 Post-installation check
Perform the following checks after mounting the device:
 Is the device undamaged (visual inspection)?
 Does the device match the measuring point specifications such as process temperature,
process pressure, ambient temperature, measuring range etc.?
 If provided: are the measuring point number and labeling correct?
Is the measuring device adequately protected against precipitation and direct sunlight?
 In the case of the field housing: are the cable glands tightened correctly?
 Is the device firmly seated on the DIN rail/is the device correctly mounted on the field
housing bracket (visual inspection)?
 Are the cover screws on the connection compartment cover of the field housing
tightened securely (visual inspection)?
