3.2 Principle of operation
The LEVEL TRANSMITTER 8136 is a radar sensor for continuous
level measurement of liquids under simple process conditions.
Dependentontheapplicationrange,dierentversionsareused:
• Level measurement of aggressive liquids in small vessels: encap-
sulated antenna system
• Flowmeasurementinopenumesorgaugemeasurementofbod-
ies of water: Plastic horn antenna
• Productswithanεrvalue≥1.8:Standard electronics
• Productswithanεrvalue≥1.5,<1.8;applicationswithverypoor
reectiveproperties:Electronics with increased sensitivity
The actual values that can be reached depend on the measurement
conditions, the antenna system or the standpipe or bypass.
The antenna of the radar sensor emits short radar pulses with a
durationofapprox.1ns.Thesepulsesarereectedbytheproduct
and received by the antenna as echoes. The transit time of the radar
pulses from emission to reception is proportional to the distance and
hence to the level.The determined level is converted into an appropri-
ate output signal and outputted as measured value.
3.3 Packaging, transport and storage
Your instrument was protected by packaging during transport. Its
capacity to handle normal loads during transport is assured by a test
based on ISO 4180.
The packaging of standard instruments consists of environment-
friendly, recyclable cardboard. For special versions, PE foam or PE
foil is also used. Dispose of the packaging material via specialised
recycling companies.
Transport must be carried out in due consideration of the notes on the
transport packaging. Nonobservance of these instructions can cause
damage to the device.
The delivery must be checked for completeness and possible transit
damage immediately at receipt. Ascertained transit damage or con-
cealed defects must be appropriately dealt with.

"Dimensions".
Warning:
The housing must not be used to screw the instrument in! Applying
tightening force can damage internal parts of the housing.
Protect your instrument against moisture ingress through the following
measures:
• Use the recommended cable (see chapter "Connectingtopower
supply")
• Tighten the cable gland
• Whenmountinghorizontally,turnthehousingsothatthecable
gland points downward
• Loop the connection cable downward in front of the cable gland
This applies particularly to:
• Outdoor mounting
• Installations in areas where high humidity is expected (e.g. through
cleaning processes)
• Installations on cooled or heated vessels
Make sure that all parts of the instrument exposed to the process are
suitable for the existing process conditions.
These are mainly:
• Active measuring component
• Processtting
• Process seal
Process conditions are particularly:
• Process pressure
• Process temperature
• Chemical properties of the medium
• Abrasionandmechanicalinuences

The strap is supplied unassembled and must be screwed to the

spring washers. Max. torque, see chapter "Technical data". Required
tools:Allenwrenchsize4.
There are two ways to screw the strap onto the sensor. Depending
on the selected version, the sensors can be swivelled in the strap as
follows:

When mounting the sensor, keep a distance of at least 200 mm
(7.874 in) to the vessel wall. If the sensor is installed in the center of
dished or round vessel tops, multiple echoes can arise.These can,
however, be suppressed by an appropriate adjustment (see chapter
"Setup").
If you cannot maintain this distance, you should carry out a false
signal storage during setup.This applies particularly if buildup on the
vessel wall is expected. In such cases, we recommend repeating the
false signal storage at a later date with existing buildup.

In vessels with conical bottom it can be advantageous to mount the
sensor in the center of the vessel, as measurement is then possible
down to the lowest point of the vessel bottom.

In liquids, direct the sensor as perpendicular as possible to the prod-

The mounting location of the radar sensor should be a place where no
otherequipmentorxturescrossthepathoftheradarsignals.
Vessel installations, such as e.g. ladders, limit switches, heating spi-
rals, struts, etc., can cause false echoes and impair the useful echo.
Make sure when planning your measuring point that the radar sensor
has a "clear view" to the measured product.
In case of existing vessel installations, a false echo storage should be
carried out during setup.
If large vessel installations such as struts or supports cause false
echoes, these can be attenuated through supplementary measures.
