3.2 Principle of operation
The VEGAFLEX 86 is a level sensor with coax probe for continuous
level or interface measurement, suitable for applications in liquids
with high temperatures up to 450 °C (842 °F).
High frequency microwave pulses are guided along a steel cable or
a rod. Upon reaching the product surface, the microwave pulses are
reected. The running time is evaluated by the instrument and output-
ted as level.

h Height - Level
Probe end tracking
To increase sensitivity, the probe is equipped with probe end tracking.
In products with a low dielectric constant, this function is very helpful.
This is the case, for example, in plastic granules, packing chips or in
uidized vessels.
Between a dielectric constant of 1.5 and 3, the function switches on, if
required. As soon as the level echo can no longer be detected, probe
end tracking is automatically activated. The measurement is continued with the last calculated dielectric constant.
The accuracy thus depends on the stability of the dielectric constant.
If you measure a medium with a dielectric constant below 1.5, probe
end tracking is always active. In this case, you have to enter the
dielectric constant of the medium. A stable dielectric constant is very
important here.
Functional principle - inter
face measur
ement
High frequency microwave impulses are guided along a steel cable or
rod. Upon reaching the product surface, a part of the microwave impulses is reected. The other part passes through the upper product
and is reected by the interface. The running times to the two product
layers are processed by the instrument.

4.1 General instructions
With instruments with threaded process tting, suitable tools must be
applied for tightening the hexagon.
Warning:
The housing must not be used to screw the instrument in! Applying
tightening force can damage internal parts of the housing.
Moisture
Protective caps
Suitability for the process
conditions
Installation position
Use the recommended cables (see chapter "Connecting to power
supply") and tighten the cable gland.
You can give your instrument additional protection against moisture
penetration by leading the connection cable downward in front of the
cable entry. Rain and condensation water can thus drain o. This ap-
plies mainly to:
outdoor mounting
•
installations in areas where high humidity is expected (e.g. through
•
cleaning processes)
installations on cooled or heated vessels
•
In the case of instrument housings with self-sealing NPT threads, it is
not possible to have the cable entries screwed in at the factory. The
openings for the cable glands are therefore covered with red protec-
tive caps as transport protection.
Prior to setup you have to replace these protective caps with approved cable glands or close the openings with suitable blind plugs.
The suitable cable glands and blind plugs come with the instrument.
Make sure that all parts of the instrument exposed to the process, in
particular the active measuring component, process seal and process
tting, are suitable for the existing process conditions. These include
above all the process pressure, process temperature as well as the
chemical properties of the medium.
You can nd the specications in chapter "Technical data" and on the
nameplate.
4.2 Instructions for installation
Mount VEGAFLEX 86 in such a way that the distance to vessel installations or to the vessel wall is at least 300 mm (12 in). In non-metallic
vessels, the distance to the vessel wall should be at least 500 mm
(19.7 in).
During operation, the probe must not touch any installations or the
vessel wall. If necessary, fasten the probe end.
In vessels with conical bottom it can be advantageous to mount the
sensor in the center of the vessel, as measurement is then possible
nearly down to the lowest point of the bottom. Keep in mind that
measurement all the way down to the tip of the probe may not be pos-

Welding work
Inowingmedium
Measuring range
Before beginning the welding work, remove the electronics module
from the sensor. By doing this, you avoid damage to the electronics
through inductive coupling.
Do not mount the instruments in or above the lling stream. Make sure
that you detect the product surface, not the inowing product.

The reference plane for the measuring range of the sensors is the
sealing surface of the thread or ange.
Keep in mind that a min. distance must be maintained below the reference plane and possibly also at the end of the probe - measurement
in these areas is not possible (dead band). These dead bands are

listed in chapter "Technical data". Keep in mind for the adjustment that
the default setting for the measuring range refers to water.
Pressure
Mounting in the vessel
insulation
The process tting must be sealed if there is gauge or low pressure in
the vessel. Before use, check if the seal material is resistant against
the measured product and the process temperature.
The max. permissible pressure is specied in chapter "Technical
data" or on the type label of the sensor.
Instruments for a temperature range up to 280 °C or up to 450 °C
have a distance piece between process tting and electronics housing. Ths distance piece is used for thermal decoupling of the electron-
ics against high process temperatures.
Information:
The distance piece must only be incorporated up to max. 50 mm (2 in)
in the vessel isolation. Only then, a reliable temperature decoupling is
guaranteed.

Steam boiler applications
Vapours, superimposed gases, high pressures and temperature differences can change the spreading speed of radar impulses.
There are two possibilities to correct these deviations.
Corrective value in the process control system
In the technical data under "Inuence of superimposed gas and pressure on accuracy" you can nd a table with deviation values in some
typical gases or in steam.
In the control system (DCS) you can correct the measurement results
of the VEGAFLEX 86 with these values.

The prerequisite is constant temperature and pressure in the vessel.
Automatic correction via the reference distance
The VEGAFLEX 86 can be equipped optionally with a running time
correction via reference distance. The probe can carry out an automatic running time correction with it.
The reference point must hence not be overlled. The upper dead
band is hence 450 mm (17.7 in).

Use a cable gland tting the cable diameter.
Make sure that the entire installation is carried out according to the
Fieldbus specication. In particular, make sure that the bus is terminated with suitable terminating resistors.
With plastic housing, the NPT cable gland or the Conduit steel tube
must be screwed without grease into the threaded insert.
Max. torque for all housings see chapter "Technical data".
With systems with potential equalisation, connect the cable screen
directly to ground potential at the power supply unit, in the connection
box and at the sensor. The screen in the sensor must be connected
directly to the internal ground terminal. The ground terminal outside
on the housing must be connected to the potential equalisation (low
impedance).
In systems without potential equalisation, connect the cable screen
directly to ground potential at the power supply unit and at the sensor.
In the connection box or T-distributor, the screen of the short stub to
the sensor must not be connected to ground potential or to another
cable screen. The cable screens to the power supply unit and to the
next distributor must be connected to each other and also connected
to ground potential via a ceramic capacitor (e.g. 1 nF, 1500 V). The
low frequency potential equalisation currents are thus suppressed,
but the protective eect against high frequency interference signals
remains.

5.2 Connection
Connection technology
The voltage supply and signal output are connected via the springloaded terminals in the housing.
The connection to the display and adjustment module or to the inter-
face adapter is carried out via contact pins in the housing.
Information:
The terminal block is pluggable and can be removed from the electronics. To do this, lift the terminal block with a small screwdriver and
pull it out. When inserting the terminal block again, you should hear it
snap in.
Connection procedure
Proceed as follows:
1. Unscrew the housing cover
2. If a display and adjustment module is installed, remove it by turning it slightly to the left.
3. Loosen compression nut of the cable entry
4. Remove approx. 10 cm (4 in) of the cable mantle, strip approx.
1 cm (0.4 in) of insulation from the ends of the individual wires
5. Insert the cable into the sensor through the cable entry

Linearization
Linearization
A linearization is necessary for all vessels in which the vessel volume
does not increase linearly with the level - e.g. a horizontal cylindri-
cal or spherical tank, when the indication or output of the volume is
required. Corresponding linearization curves are preprogrammed
for these vessels. They represent the correlation between the level
percentage and vessel volume.
The linearization applies for the measured value indication and the
current output. By activating the suitable curve, the percentage vessel
volume is displayed correctly.
False signal suppression
High sockets and internal vessel installations cause interfering reections and can inuence the measurement.
A false signal suppression detects, marks and saves these false
signals so that they are no longer taken into account for the level and
interface measurement. We generally recommend carrying out a false
signal suppression to achieve the best possible accuracy. This should
be done with the lowest possible level so that all potential interfering
reections can be detected.
Enter the actual distance from the sensor to the product surface.
All interfering signals in this section are detected by the sensor and
stored.
The instrument carries out an automatic false signal suppression
as soon as the probe is uncovered. The false signal suppression is
always updated.

Setup - Linearization
Setup - Scaling Level
A linearization is necessary for all vessels in which the vessel volume
does not increase linearly with the level - e.g. a horizontal cylindri-
cal or spherical tank, when the indication or output of the volume is
required. Corresponding linearization curves are preprogrammed
for these vessels. They represent the correlation between the level
percentage and vessel volume.
The linearization applies to the measured value indication and the
current output. By activating the appropriate curve, the volume percentage of the vessel is displayed correctly. If the volume should not
be displayed in percent but e.g. in l or kg, a scaling can be also set in
the menu item "Display".
Caution:
Note the following, if the respective sensor is used as part of an overll protection system according to WHG:
If a linearization curve is selected, the measuring signal is no longer
linearly proportional to the level. This must be taken into consideration
by the user, particularly when setting the switching point on the limit
signal indicator.
Since the scaling is very comprehensive, the scaling of the level value
was divided into two menu items.

Note:
A false signal suppression detects, marks and saves these false
signals so that they are no longer taken into account for the level and
interface measurement. We generally recommend carrying out a false
signal suppression to achieve the best possible accuracy. This should
be done with the lowest possible level so that all potential interfering
reections can be detected.
Proceed as follows:
Enter the actual distance from the sensor to the product surface.
All interfering signals in this section are detected by the sensor and
stored.
Note:
Check the distance to the product surface, because if an incorrect
(too large) value is entered, the existing level will be saved as a false
echo. The lling level would then no longer be detectable in this area.
If a false signal suppression has already been created in the sensor,
the following menu window appears when selecting "False signal
suppression":
The instrument carries out an automatic false signal suppression
as soon as the probe is uncovered. The false signal suppression is
always updated.
The menu item "Delete" is used to completely delete an already created false signal suppression. This is useful if the saved false signal

7.2 Parameter adjustment with PACTware
For parameter adjustment of the sensor via a Windows PC, the conguration software PACTware and a suitable instrument driver (DTM)
according to FDT standard are required. The up-to-date PACTware
version as well as all available DTMs are compiled in a DTM Collec-
tion. The DTMs can also be integrated into other frame applications
according to FDT standard.
Note:
To ensure that all instrument functions are supported, you should
always use the latest DTM Collection. Furthermore, not all described
functions are included in older rmware versions. You can download
the latest instrument software from our homepage. A description of
the update procedure is also available in the Internet.
Further setup steps are described in the operating instructions manu-
al "DTM Collection/PACTware" attached to each DTM Collection and
which can also be downloaded from the Internet. Detailed descriptions are available in the online help of PACTware and the DTMs.

Interface measurement: If you select "Interface", the instrument needs
more information, such as the distance to the interface, the dielectric
constant of the upper medium or whether or not there is a superim-
posed gas phase.
Demonstration mode: This mode is suitable for test and demonstration purposes. In this mode, the sensor ignores all logic parameters
and reacts immediately to all measured value changes within the
measuring range.
Application - Level measurement
The level measurement refers to the product surface which is the limit
to the gas phase.
Liquids
•
– Solvents, oils, LPG - dielectric constant < 3
– Chemical mixtures - dielectric constant 3 … 10
– Water-based - dielectric constant > 10
Bulk solids
•
– Dusts, wood chips - dielectric constant < 1.5
– Granules, dusts, powders - dielectric constant 1.5 … 3
– Cereals, our - dielectric constant > 3
Application - Interface measurement
The interface measurement refers to the phase limit between two
liquids. The total level is also available as a measured value.
Superimposed gas phase present
•
– Check if there is a superimposed gas phase in the vessel. This
is always the case if the total level never touches the process
tting.

Adjustment for the level measurement
If you have selected level measurement in the previous menu, then
you can enter the values for the min. and max. adjustment. The value
to be entered refers to the distance from the sealing surface of the
process tting (sensor reference plane) to the surface of the product.
Adjustment for the level and interface measurement
If you have selected interface measurement in the previous menu,
then you can enter the values for the min. and max. adjustment of
level and interface or accept the values of the level measurement. The
entered value refers to the distance from the sealing surface of the
process tting (sensor reference plane) to the total level or interface.
Linearization is required if the measured value should be outputted
in proportion to the volume and not the level. The linearization acts
identically on the level and the interface measurement. You can nd
further linearization types in the extended adjustment.
If you have a non-linear vessel, you can select here the respective

•
When the instrument is shipped, the measured value memory is
active and stores distance, measurement certainty and electronics
temperature every 3 minutes.
In the "Extended operation", you can select the respective measured
values.
The requested values and recording conditions are set via a PC with
PACTware/DTM or the control system with EDD. Data are thus read
out and also reset.
Up to 500 events are automatically stored with a time stamp in the
sensor (non-deletable). Each entry contains date/time, event type,
event description and value. Event types are for example:
Modication of a parameter
•
Switching on and o times
•

user.
Function check: The instrument is in operation, the measured value
is temporarily invalid (for example during simulation).
This status message is inactive by default. It can be activated by the
user via PACTware/DTM or EDD.
Outofspecication: The measured value is unstable because the
instrument specication is exceeded (e.g. electronics temperature).
This status message is inactive by default. It can be activated by the
user via PACTware/DTM or EDD.
Maintenance: Due to external inuences, the instrument function
is limited. The measurement is aected, but the measured value is
still valid. Plan in maintenance for the instrument because a failure is
expected in the near future (e.g. due to buildup).

Treatment of measurement errors
The below tables show typical examples for application-relevant
measurement errors. There are two measurement errors:
Constant level
•
Filling
•
Emptying
•
The images in column "Error pattern" show the real level with a broken line and the level displayed by the sensor as a continuous line.

Note:
Wherever the sensor displays a constant value, the reason could

also be the fault setting of the current output to "Hold value"
In case of a too low level indication, the reason could be a line

resistance that is too high

The propagation speed of the radar impulses in gas or vapour above the medium is reduced by
high pressure. This eect depends on the superimposed gas or vapour and is especially large at
low temperatures.
The following table shows the resulting deviation for some typical gases and vapours. The specied
values refer to the distance. Positive values mean that the measured distance is too large, negative
values that the measured distance is too small.

11.2 Basics Modbus
Bus description
The Modbus protocol is a communication protocol for the communication between instruments. It is
based on a Master/Slave or Client/Server architecture. By means of Modbus, a Master and several
Slaves can be connected. Each bus participant has an unambiguous address and can send messages to the bus. This is initiated by the Master, the addessed Slave answers. The versions Ethernet
and serial (EIA-232 and EIA-485) as well as the modes ASCII, TCP and RTU are available for the
data transfer. In the RTU and ASCII mode interesting here, data will be transmitted in binary form.
The telegram consists generally of the address, the function, the data as well as the transmission
check.
Bus architecture
In the version Modbus RTU, up to 32 participants can be connected to the bus. The length of the
twisted two-wire cable can be up to 1200 m. The bus must be terminated on both sides at the last
bus participant with a terminating resistor of 120 Ohm. The resistor is already integrated in the
VEGAFLEX 86 and is activated/deactivated via a slide switch.

Generalcongurationofthehost
The data exchange with status and variables between eld device and host is carried out via
register. For this, a conguration in the host is required. Floating point numbers with short prevision
(4 bytes) according to IEEE 754 are transmitted with individually selectable order of the data bytes
(byte transmission order). This "Byte transmission order" is determined in the parameter "Format
Code". Hence the RTU knows the registers of the VEGAFLEX 86 which must be contacted for the
variables and status information.

11.5 Levelmaster commands
The VEGAFLEX 86 is also suitable for connection to the following RTUs with Levelmaster protocol.
The Levelmaster protocol is often called "Siemens" "Tank protocol".
RTU Protocol
ABB Totalow Levelmaster
Kimray DACC 2000/3000 Levelmaster
Thermo Electron Autopilot Levelmaster
Parameters for the bus communication
The VEGAFLEX 86 is preset with the default values:
Parameter CongurableValues Default Value
Baud Rate 1200, 2400, 4800, 9600, 19200 9600
Start Bits 1 1
Data Bits 7, 8 8
Parity None, Odd, Even None
Stop Bits 1, 2 1
Address range Levelmaster 32 32
The Levelmaster commands are based on the following syntax:
Capital letters are at the beginning of certain data elds
•
Small letters stand for data elds
•
All commands are terminated with "<cr>" (carriage return)
•
All commands start with "Uuu", whereby "uu" stands for the address (00-31)
•
"*" can be used as a joker for any position in the address. The sensor always converts this in
•
its address. In case of more than one sensor, the joker must not be used, because otherwise
several slaves will answer
Commands that modify the instrument return the command with "OK“. "EE-ERROR" replaces
•
"OK" if there was a problem changing the conguration
