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.

Terminal compartment of the field housing

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.

Limitation of electrical safety.

‣ When using the public supply mains, an easily accessible power switch must be installed in the

proximity of the device. The power switch must be marked as a disconnector for the device (IEC/
EN 61010).

In order to avoid interference, do not route the sensor cables parallel to high-voltage or
electric power lines and not close to frequency converters.

Synchronization line

• If wiring several Prosonic S (FMU90/FMU95)
which are mounted in a common cabinet and if
the sensor cables run in parallel, the
synchronization terminals (39 and 40) must be
interconnected.

• Up to 20 instruments can be synchronized in
this way.

• The synchronization prevents an evaluation
unit from receiving a signal while a different
evaluation unit is emitting a signal.
This prevents pulses in the sensor cable of one
sensor from influencing the received signal on
the cable of a different sensor.

• If there are more than 20 instruments, groups
must be formed, each containing a maximum of
20 instruments. For the instruments within
each group, the sensor cables may run in
parallel. The sensor cables of different groups
must be seperated from each other.

• Usual commercial screened cable can be used
for synchronization
– max. length: 10 m (33 ft) between the

individual instruments

– cross section: 2 x (0.75 to 2.5 mm

2

(20 to 14 AWG))

– for lengths up to 1 m (3.3 ft), an unscreened

cable can be used; for lenghts exceeding 1 m
(3.3 ft), screening is required. The screen
must be connected to ground

• Instruments of the Prosonic FMU86x family
can be connected to the synchronization line as
well. In this case a maximum of 10 instruments
can be connected to each synchronisation line.

Prosonic S FMU95

Performance characteristics

Reference operating conditions

• Temperature = 24±5 °C (75±9 °F)

• Pressure = 960±100 mbar (14±1.45 psi)

• Relative humidity = 60±15 %

• Ideally reflecting surface, sensor vertically aligned
(e.g. calm, plane liquid surface of 1 m

• No interference echoes within the signal beam

• Settings of the application parameters:
– Tank shape = flat ceiling; Medium property = liquid; Process condition = calm surface

4)

Maximum measuring error

Typical measuring error

5)±0,2 % of the maximum span of the sensor

5)

Include linearity, repeatability and hysteresis
Better than ±2 mm (0.08 in) + 0.17 % of the measured distance

Measured value resolution 1mm (0.04in) with FDU90/FDU91

Measuring frequency • 0.2 Hz (with 5 sensors)

• 0.1 Hz (with 10 sensors)

The exact value depends on the settings of the application parameters and the instrument version
(5 sensors or 10 sensors).

If unused sensor inputs are switched off (in the "sensor management" menu), the measuring
frequency increases. The Prosonic S measures with one sensor per second.

Certificates and Approvals

CE mark The measuring system meets the legal requirements of the EC-guidelines. Endress+Hauser confirms

the instrument passing the required tests by attaching the CE-mark.

Ex approval The available certificates are listed in the ordering information. Note the associated safety instructions

(XA) and control or installation drawings (ZD).

Warning!

• 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 standards and 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.

• For FM approvals:
Unauthorized substitution of components may impair the suitability for Division 1 or Division 2.

• Do not disconnect equipment unless the area is known to be non-hazardous.

Note!

• The sensor must be installed and used in a way that eliminates any danger. Possible installation
positions: in tanks, vessels, silos, over stockpiles, open channels, weirs or other bins.

• Sensors FDU9x with Ex-approval can be connected to the transmitter FMU95 without Ex-approval.
