Measuring principle
Function and system design
L00-FMU95xxx-15-00-08-xx-900
BD: Blocking distance, D: Distance from sensor membrane to fluid surface, E: Empty distance F: Span (full distance),
L: Level, V: Volume (or mass)
The sensor transmits ultrasonic pulses in the direction of the product surface. There, they are reflected
back and received by the sensor. The transmitter Prosonic S measures the time t between pulse
transmission and reception. From t (and the velocity of sound c) it calculates the distance D from the
sensor membrane to the product surface:
D = c · t/2
From D results the desired measuring value:
• Level L
•Volume V
Blocking distance The span F may not extend into the blocking distance BD. Level echoes within the blocking distance
range can not be evaluated due to the transient characteristics of the sensor.
The blocking distances of the individual sensors are given in the following documents:
• TI00396F for the sensors FDU90/91/91F/92/93/95
1)
Time-of-flight correction In order to compensate for temperature dependent time-of-flight changes, a temperature sensor
(NTC) is integrated in the ultrasonic sensors.
Interference echo suppression
The interference echo suppression feature of the Prosonic S ensures that interference echoes (e.g. from
edges, welded joints and installations) are not interpreted as a level echo.
Linearization Pre-programmed linearization curves for specific types of vessels
• Horizontal, cylindrical tank
•Spherical tank
• Tank with pyramidal bottom
• Tank with conical bottom
• Tank with flat, inclined bottom
The pre-programmed linearization curves are calculated on-line.
Linearization table
consisting of up to 32 linearization points; to be entered manually or half-automatically.

The field housing has a separate terminal compartment. It can be opened after loosening the 4 screws
of the lid.
L00-FMU90xxx-04-00-00-xx-002
For easier wiring, the lid can be completely removed by unplugging the display plug and loosening the
hinges:
L00-FMU90KAx-04-00-00-xx-009
Cable entries of the field housing
On the bottom of the housing the following openings for cable entries are prestamped:
• M20x1.5 (10 openings)
• M16x1.5 (5 openings)
• M25x1.5 (1 opening)
A suitable cutting device must be used for cutting out the openings.

• If the instruments are mounted next to each other and if the sensor cables run in parallel, the
synchronization terminals (39 and 40) must be interconnected (see sections → ä 9 "Terminal
assignment" and → ä 12 "Synchronization line").
