Technical
Information
TI 365F/24/ae
Ultrasonic Level Measurement
prosonic M FMU 40/41/43
Compact transmitters for non-contact level
measurement of fluids, pastes and coarse
bulk materials
FMU 40
Application
The compact Prosonic M transmitters are
used for continuous, non-contact level
measurement in fluids and coarse bulk
materials.
Additionally, the sensors can be used for
flow measurement in open channels and
measuring weirs.
The following interfaces are available for
system integration:
• HART ® (standard), 4 to 20 mA
• PROFIBUS-PA
• Foundation Fieldbus
The maximum measuring range for
Prosonic M sensors are:
• FMU 40:
– Fluids, 16 feet (5 m)
– Bulk solids, 6 feet (2 m)
• FMU 41:
– Fluids, 26 feet (8 m)
– Bulk solids, 12 feet (3.5 m)
• FMU 43:
– Fluids, 50 feet (15 m)
– Bulk solids, 23 feet (7 m)
FMU 41
Features and benefits
• Simple, menu-guided on-site
operation with four-line plain text
display
• Envelope curves on the on-site
display for simple diagnosis
• Easy operation, diagnosis and
measuring point documentation with
the supplied ToF Tool operating
program
• Alignable NEMA 6P (IP 68) aluminum
housing
• Optional remote display and operation
• Installation via 1-1/2" NPT, 2" NPT
or 4" universal slip-on flange
• Integrated temperature sensor for
Time-of-Flight correction provides
accurate measurements, even with
temperature changes
• Linearization function (up to 32 points)
for measured value output in any unit
of length, volume, or flow rate
• Non-contact measurement method,
therefore almost independent of
product properties
