3.3 Installation conditions

3.3.1 Installation conditions for level measurements

L00-FMU30xxx-17-00-00-xx-005

• Do not install the sensor in the middle of the tank (3). We recommend leaving a distance between
the sensor and the tank wall (1) measuring 1/6 of the tank diameter.

• Protect the device against direct sun or rain (2), e.g. with a weather protection cover, see the
technical information TI00440F, chapter "Accessories".

• Avoid measurements through the filling curtain (4).

• For solid application where bulk solid cones appear, align the sensor membrane perpendicular to
the surface.

• Make sure that equipment (5) such as limit switches, temperature sensors, etc. are not located
within the emitting angle . In particular, symmetrical equipment (6) such as heating coils, baffles
etc. can influence measurement.

• Never install two ultrasonic measuring devices in a tank, as the two signals may affect each other.

• To estimate the detection range, use the 3 dB emitting angle .

V Direction of flow

In narrow shafts with strong interference
echoes, we recommend using an ultrasound
guide pipe (e.g. PE or PVC wastewater pipe)
with a minimum diameter of 100 mm (3.94 in).
Make sure that the pipe is not soiled by accumu­lated dirt. If necessary, clean the pipe at regular
intervals.

3.4 Measuring range

3.4.1 Blocking distance, Nozzle mounting

Install the instrument at a height so that the blocking distance BD is not undershot, even at
maximum fill level. Use a pipe nozzle if you cannot maintain the blocking distance in any other way.
The interior of the nozzle must be smooth and may not contain any edges or welded joints. In
particular, there should be no burr on the inside of the tank side nozzle end. Note the specified limits
for nozzle diameter and length. To minimise disturbing factors, we recommend an angled socket
edge (ideally 45°).

"

Caution!
If the blocking distance is undershot, it may cause device malfunction.

!

Note!
In order to notice if the level approaches the blocking distance, you can specify a safety distance
(SD). If the level is within this safety distance, the instrument outputs a warning or alarm message.

3.4.2 Safety distance

If the level rises to the safety distance SD, the device switches to warning or alarm status.
The size of SD can be set freely in the "Safety distance" (015) function.The "in safety distance"
(016) function defines how the device reacts if the level enters the safety distance.

There are three options:

• Warning: The device outputs an error message but continues measurement.

• Alarm: The device outputs an error message. The output signal assumes the value defined in the
"Output on alarm" (011) function (MAX, MIN, user-specific value or holds the last value). As
soon as the level drops below the safety distance, the device recommences measurement.

• Self holding: The device reacts in the same way as for an alarm. However, the alarm condition
continues after the level drops below the safety distance. The device only recommences
measurement when you cancel the alarm using the "Ackn. alarm" (017) function.

3.4.3 Range

The sensor range is dependent on the measuring conditions. Refer to Technical Information
TI00440F/00/EN for an estimation. The maximum range is shown in the above diagram (valid for
good conditions).

3.5 Installation hint

3.6 Installation check

After installing the device, carry out the following checks:

• Is the device damaged (visual inspection)?

• Does the device correspond to the measuring point specifications for process temperature, process
pressure, ambient temperature, measuring range etc.

• If available: Are the measuring point number and labelling correct (visual inspection)?

• Is the measuring device sufficiently protected against precipitation and direct sunlight?

• Are the cable glands tightened correctly?

• After aligning the housing, check the process seal at the nozzle or flange.

"

Caution!
In Ex applications, the instrument must only be grounded on the sensor side. Further safety
instructions are given in the separate documentation for applications in explosion hazardous areas.

!

Note!
Since the housing is isolated from the tank by the plastic sensor, interference signals may occur if
the potential matchin gline is not prolerly connected.
For optimum electromagnetic compatibility the potential matching line should be as short as
possible and at least 2.5 mm

(14 AWG) in cross-section.
If increased electromagnetic interference is to be expected due to the installation conditions, we
recommend usage of a ground strap.

4.5 Checking the connection

After wiring the device, carry out the following checks:

• Are the terminals correctly assigned?

• Is the cable gland tight?

• Is the housing cover fully screwed on?

• If power supply available: Does a display appear on the display module?

5.7 Resetting the customer parameters

It is advisable to reset the customer parameters if you want to use a device with an unknown history.

Effects of resetting:

• All customer parameters are reset to their default values.

• Customer interference echo suppression is not deleted.

• Linearisation is switched to "linear", but the table values are kept. The table can be switched
back on in the "linearisation" (04) function group in the "linearisation" (041) function.

In order to carry out the reset, enter the number "333" in the "reset" (0A3) function in the
"diagnostics" (0A) function group.

"

Caution!
A reset may lead to impairment of the measurement. As a rule, a basic calibration is required after
a reset.

!

Note!
The default values of each parameter are shown in bold in the menu overview in the appendix.

5.8 Resetting an interference echo suppression (tank map)

It is always advisable to reset the interference echo suppression (tank mapping) when:

• a device with an unknown history is used

• an incorrect suppression was input.

Proceed as follows:

1. Switch to the "extended calibr." (05) function group and to the "selection" (050)

function.

2. Select "extended map."

3. Then proceed to the "cust. tank map" (055) function.

4. Select

– "reset", to delete (reset) the existing interference echo suppression.
– "inactive" to deactivate an existing interference echo suppression. The suppression remains

saved.

– "active" to reactivate an existing interference echo suppression.

In the "dist./meas.value" (008) function, the measured distance D from the sensor membrane
to the product surface is displayed together with level L. Check these values.

Function "check distance" (051)

The mapping is initialized by this function.

L00-FMU3KAxxx-14-00-06-xx-010

1 Distance too small
2Distance = ok

Select

• "distance=ok" if the correct distance is displayed. Any echoes closer to the sensor will be
suppressed by the following interference echo suppression.

• "dist. too small" if the displayed distance is too small. In this case, the signal comes from an
interference echo which will be suppressed.

• "dist. too big" if the displayed distance is too large. This error cannot be cancelled by suppressing
the interference echo. This means that the following two functions are skipped. Check the
application parameters "tank shape" (002), "medium property" (003) and "process
cond." (004) and the "empty calibr."(005) in the "basic setup" (00) function group.

• "dist. unknown" if you do not know the actual distance. This means that the following two
functions are skipped.

• "manual" if you want to specify the suppression area yourself in the following function.

Function "range of mapping" (052)

The suggested suppression area is displayed in this function. The reference point is always the sensor
membrane. You can still edit the value. With manual suppression, the default value is 0 m.

• on: Starts suppression.

!

Note!
If a mapping already exists, it will be overwritten up to the distance specified in the "range of

mapping" (052) function. Beyond this distance the existing mapping remains unchanged.

Function dist./measured value (008)

After suppression, the measured distance D from the sensor membrane to the product surface is
displayed together with the level. Check that the values correspond to the actual level and/or the
actual distance.

The following cases may occur:

• Distance correct – Level correct -> End of basic calibration

• Distance incorrect – Level incorrect -> An additional interference echo suppression must be
carried out. Go back to the "check distance" (051) function.

• Distance correct – Level incorrect -> Check the value of the "empty calibr." (005) function.

Return to group selection

After the interference echo suppression the basic setting is finished and the instrument jumps
automatically back into the group selection.

6.3 Envelope curve

After the basic setup, an evaluation of the measurement with the aid of the envelope curve
("envelope curve" (0E) function group) is recommended.

Check that the following conditions are fulfilled:

• The echo quality at the end of measuring range should be at least 10 dB.

• There should be practically no interference echoes in front of the level signal.

• If interference echoes cannot be avoided, they must be below the suppression curve.

!

Note!
If the cyclical envelope curve display is still active on the display, the measured value is updated at
a slower cycle time. We therefore advise you to exit the envelope curve display after optimising the
measuring point. To do this, press E. (The instrument does not leave the envelope curve display
automatically.)

8 Maintenance and repairs

8.1 Exterior cleaning

When cleaning the exterior, always use cleaning agents that do not attack the surface of the housing
and the seals.

8.2 Repairs

The Endress+Hauser repair concept assumes that the measuring devices have a modular design and
that customers are able to undertake repairs themselves  ä 41, "Spare Parts". For more
information on service and spare parts, contact the Service Department at Endress+Hauser.

8.3 Repairs to Ex-approved devices

When carrying out repairs to Ex-approved devices, please note the following:

• Repairs to Ex-approved devices may only be carried out by trained personnel or by the
Endress+Hauser Service.

• Comply with the prevailing standards, national Ex-area regulations, safety instructions (XA) and
certificates.

• Only use original spare parts from Endress+Hauser.

• When ordering a spare part, please note the device designation on the nameplate. Only replace
parts with identical parts.

• Carry out repairs according to the instructions. On completion of repairs, carry our the specified
routine test on the device.

• Only Endress+Hauser Service may convert a certified device into a different certified variant.

• Document all repair work and conversions.

8.4 Replacement

After a complete instrument or electronic module has been replaced, the parameters can be
downloaded into the instrument again via the communication interface. Prerequisite to this is that
the data were uploaded to the PC beforehand using FieldCare. Measurement can continue without
having to carry out a new setup. Only a linearisation and a tank map (interference echo suppression)
have to be recorded again.

Influence of the vapor pressure The vapor pressure at 20 °C (68 °F) gives a hint on the accuracy of the ultrasonic level

measurement. If the vapor pressure at 20 °C (68 °F) is below 50 mbar (0.73 psi), ultrasonic level
measurement is possible with a very high accuracy. This is valid for water, aqueous solutions, water­solid-solutions, dilute acids (hydrochloric acid, sulfuric acid, ...), dilute bases (caustic soda, ...), oils,
greases, slurries, pastes, ...
High vapor pressures or outgassing media (ethanol, acetone, ammonia, ...) can influence the
accuracy. If conditions like these are present, please contact the Endress+Hauser support.

11.2 Measuring principle

L00-FMU30-15-00-00-xx-001

BD Blocking distance D Distance from sensor membrane - product surface
E Empty distance F Span (full distance)
L Level

11.2.1 Time-of-flight method

The sensor of the instrument transmits ultrasonic pulses in the direction of the product surface.
There, they are reflected back and received by the sensor. The instrument measures the time t
between pulse transmission and reception. The instrument uses the time t (and the velocity of sound
c) to calculate the distance D between the sensor membrane and the product surface:

D = c  t/2

As the device knows the empty distance E from a user entry, it can calculate the level as follows:

L = E - D

An integrated temperature sensor compensates for changes in the velocity of sound caused by
temperature changes.

11.2.2 Interference echo suppression

The interference echo suppression feature on the instrument ensures that interference echos (e.g.
from edges, welded joints and installations) are not interpreted as a level echo.

11.2.3 Calibration

Enter the empty distance E and the span F to calibrate the device.

11.2.4 Blocking distance

Span F may not extend into the blocking distance BD. Level echos within the blocking distance
cannot be evaluated due to the transient characteristics of the sensor.
