Chapter 2 General Information
2.3 Intended Use
The measuring system DynFAS MW can be used to determine the
concentration of nearly all materials which can be dissolved or suspended in water using microwave technology. The following sensor
and control unit versions are available:
1. The container probes have been designed for installation into
pipelines with a nominal width of ≥ 200 mm and in containers,
for example, crystallizers. The probe is installed such that both
measuring rods (transmitter and receiver) are immersed into
the product being measured.
2. The Flow Cell is a tubular probe, with microwave transmitter
and receiver being firmly welded onto the outside of t he pipe.
The inside of the pipe is Teflon-coated. The flow cell is installed into the existing pipeline system inline or into a bypass.
The control unit is available in two versions: The Standard Model
CS-100 and the high dynamic version CH-200. The control unit
CH-200 can only be used when sufficiently large microwave attenuation (min. 40 dB) is present. The Standard Model CS-100
should be used for lower microwave attenuation.
During operation, the concentration measuring device DynFAS MW
send out electromagnetic radiation in the frequency range between
2.4 GHz and 2.5 GHz (range restrictions depending on local regu-
lations in your country). The microwaves which emerge are not
dangerous to human beings and the environment (power emission
< 10 mW). The microwaves are emitted from the microwave window; the product is not changed by the microwaves.
To ensure proper function of the meter, please pay attention to the
following:
14
Tip
¾ The material being measured must not be electrically conduc-
tive, i.e. the ohmic resistance is infinite.
¾ The product must not contain any gas bubbles, or gas bubbles
have to be compressed with adequate pressure when carrying
out measurements in pipelines.
¾ The ion concentration, e.g. salt content, has to be nearly con-
stant.
¾ The total attenuation of microwave signals must be at least 40
dB for the control unit CH-200. For details, see Chapter 3.4.1

Chapter 3. System Description
3.1 Principle of Measurement
The microwaves that spread between the rods pass through the
product being measured; their propagation speed is slowed down
(= phase shift) and their intensity is damped (= attenuation).
Figure 3-1 illustrates the principle of measurement: the propagation speed of microwaves passing through the product being
measured is slowed down (phase shift) and their intensity (attenuation) is reduced, relative to a reference signal.

Phase shift
Prerequisite is that the product being measured shows some
dielectric properties. In general, water is a very distinct dielectric fluid. The water or dry mass concentration, respectively, can
therefore be determined by measuring the phase shift and/or
attenuation.
The concentration to be detected in the product is therefore dependent in good approximation linear on phase shift and attenuation. For this reason we can measure the concentration or
the Brix content of the product using a linear calibration (see
chapter 3.2 Calculation of Measured Values ).

DynFAS MW
Chapter 3 System Description

3.2 Calculation of Measured Values
The microwave measuring phase and attenuation are calibrated
after an automatic plausibility analysis.
During calibration, the phase and/or the attenuation or a concentration value (or density value) are assigned by sampling. The
calibration is full automatic and the sample taking is supported by
the control unit.
Which of the parameters, either phase, attenuation or both are
used for the calibration depends on the size and interference of the
measuring effect. For example, the attenuat ion is significantly
more sensitive to electrolytic conductivity (salt content).
In many cases, the mere phase measurement is recommended
and is calculated in good approximation by a linear calibration as
follows:
=
Con concentration
A, C coefficients of respective calibration function
ϕ phase
The DynFAS MW allows you to calibrate, display and output two
concentrations Con1 and Con2. You have to enter the calibration
coefficients separately for concentration 1 and 2. For more information please refer to the Software Manual.

3.3 Temperature Compensation
Temperature compensation (TC) is necessary if the product temperature varies. In general, we recommend connecting a temperature compensation, i.e. a temperature signal (0/4...20 mA or
Pt 100) to the control unit and, if necessary, to enable the compensation in the control unit. The control unit is designed such that
the required TC’s can be calculated automatically. The variat ion in
temperature where temperature compensation becomes absolutely
essential is dependent on the product and on the water content. In
first approximation, ± 2°C should be set as fluctuation limit.
Tip
TC has to be carried out whenever you are working with.
The TC corrects the phase and attenuation before the measured
value calculation (calibration), in most applications according to
the following formulae (linear compensation, additive).

)
Depending on the selected function (additive, multiplicative, lin ear,
quadratic), the required temperature coefficients appear on the
Calibration menu. Temperature coefficients that are not used are
set to zero.
If you select two-range calibration (split concentration), separate
TC’s have to be entered for both concentration ranges. The coefficients are entered in the course of calibration.
TC can be carried out via Pt 100 or via current input. This has to
be defined on the Calibration menu. The Pt 100 temperature range
is between –50°C and +200°C.
How to work with the temperature compensation is described in
detail in the Software Manual.

Differences between Control Unit Standard CS-100 and
Control Unit High Dynamic CH-200
The Control Unit High Dynamic CH-200, has an additional HF amplifier module in comparison to the standard model, whereby the
wall housing is larger (dimensions see chapter 6.2 Technical Data
control unit). Otherwise, the control units only differ in their applications.
Higher product attenuations are allowed for the high dynamic version of DynFAS MW. Therefore larger measuring paths can be irradiated, for example measuring cells of larger nominal width can be
used. The application of both control units is predetermined by the
product attenuation. Up to an attenuation of 50 dB, CS-100 is used
and beyond, CH-200. The CH-200 generally requires an attenuation of 40 dB. If this is lower, the software indicates an err or message.
An RS232 interface is included on the underside of the instrument.

The container probe has been specially designed for concentration
measurements in containers. Both measuring rods are immersed
into the product. Microwaves are emitted from one end of the rod
and received by the other end of the rod; they are emitted only
towards the opposite end of the rod. This direction characteristic of
the probe minimizes the interfering influence of metal parts in the
vicinity of the probe and allows installation if only little space is
available. For example, the concentration of sugar strike can be
measured continuously to find the suitable inoculation time.
The plastic rods meet the special requirements for application in
foodstuffs.

DynFAS MW
Chapter 3 System Description
Two different probe types are available:
¾ The standard type is the container probe without flushing de-
vice
¾ The probe with flushing is employed in processes where incrus-
tations are likely to occur, for example, due to increased depositions. The flushing device prevents any deposition on the microwave exit windows. Long travel times are supported by continuous crystal processes (i.e. VKT).
The flow direction of the product being measured should be vertical, as shown in Figure 3-12. This ensures that the product between the measuring rods is representative, provided it is mixed
thoroughly.

Chapter 3 System Description
3.4.4 High-Frequency Cable
High-frequency cables (HF cable) are used to transmit microwaves
between probe and evaluation electronics.
HF cables change their conductivity (for microwaves) relative to
the temperature. Therefore, variations in the ambient temperature
would create measurement errors. This error is compensated for
by enabling the cable compensation. Influences of the ambient
temperature on the signal cable are compensated for by means of
the reference cable. The reference cable has the same length as
the signal cable; during operation, it should be exposed to the
same ambient temperature. Therefore, we recommend installing
both cable types together in a corrugated tube; this also simplifies
installation.
The HF cable quad (see Figure 3-16) consists of four individual HF
cables of the same length, which each end with one HF plug connector (N-type). Available cable lengths: 2, 4, 6 and 10 m.
When connecting the Flow Cell, the reference cable is shortcircuited to the probe side by means of N-connectors (see Figure
3-17).

Never bend HF cables! The bending radius should not be less than

Chapter 3 System Description
3.5 Pipeline Measurement Configuration
The control unit is installed in the immediate vicinity of the container probe to keep the HF-cable between control unit and probe
fairly short. The shorter the cable connection, the better the stability of the measurement. The standard length is 4 m and the maximum length of the HF-cables is 10 m.
The flow cell is installed into the exist ing pipeline system inline or
into a bypass. The orientation of the flow cell may either be vertical or horizontal. To rule out sedimentary depositions, vertical installation in a riser is preferred (see Figure 3-18).
The flow cell should be installed fairly close to the sampling location to ensure representative sampling for calibration.
For possibly required product temperature compensation, a representative temperature signal (current signal or Pt 100) has to be
connected to the control unit.

Chapter 3 System Description
3.6 Container Measurement Configuration
The control unit is installed in the immediate vicinity of the probe
to keep the HF-cable between control unit and probe fairly short.
The shorter the cable connection, the better the stability of the
measurement. The standard length is 2 or 4 m and the maximum
length of the HF-cables is 10 m.
The control unit should be installed fairly close to the sampling
location to ensure representative sampling for calibration. A representative temperature signal (current signal or Pt 100) should be
connected to the control unit for possibly required product temperature compensation.
Our example below shows the measurement configuration on a
discontinuous evaporation crystallizer. The probe is fixed to the
container wall such that both measuring rods are immersed into
the product.

4.1 Transport
IMPORTANT
Risk of damage!
System parts may get damaged during transportation!
Transport probe and control unit in their original packaging. Protect parts against shocks. Especially the plastic rods of the container probes have to be protected against mechanical impact!
After unpacking, make sure all parts listed on the packing list have
been delivered and show no sign of damage; if necessary, clean
these parts.
If you detect any damage, please notify the forwarder and the
manufacturer immediately.
The weight of the system components can amount to more than
25 kg depending on the model. You should wear safety shoes.
4.2 Installation
4.2.1 Flow Cell Installation
For installation of the flow cell please keep in mind:
¾ The flow cell is installed into the pipelin e system. Keep in mind
that material sampling should be possible for calibration directly behind the flow cell.
¾ The flow cell should be installed in a vertical riser, if possible. It
has to be ensured that no material depositions occur on the pipe walls and no bubbles are present in the product. For horizontal installation, please observe the correct orientation of the
HF-connections (see Figure 4-2).
32
¾ There should be a straight pipe section of at least 200 mm and
equal nominal width before and after the flow cell to ensure a
fairly homogeneous flow profile and to rule out possibly occurring microwave reflections in the pipeline.
DynFAS MW
Chapter 4 Getting Started
¾ No gas bubbles should be present in the product. If gas bub-
bles cannot be ruled out, a pressure of at least 4 bar is required in the pipeline to minimize the influence of gas bubbles.
Please observe the max. permissible working pressure (see
chapter 6.2 Technical Data Sensors)
¾ The high-frequency cable should preferably be connected to
the flow cell from below to prevent inflowing water from getting
to the connecting sockets.
¾ The HF cable should not come into contact with the warm pipe-
lines.

4.2.2 Container Probe Installation
For installation, please keep in mind:
¾ Select the installation site such that good mixing and a homo-
geneous product are ensured and no bubbles are present in the
probe. A tap should be provided in the direct vicinity to allow
representative sampling.
¾ The probe has to be flange-mounted on the container such that
the product being measured flows between both measuring
rods. That means the fork (both measuring rods) has to be installed at an angle of 90° to the material flow.
¾ The distance between the measuring rod tips and any metal-
ized walls (heating elements, stirrer, container wall) should be
at least 60 mm.
¾ The following installation hole sizes in the fitting flange
are required for installation of the probe:
Flange
DN 65 / PN 6
others
¾ For further installation dimensions please refer to chapter 8
(see installation sheets).
¾ Use the respective flat gasket (standard accessory) to compen-
sate for minor surface tolerances in the fitting flange.

Installation on Process Containers
Figure 3-19 shows the position of the container probe on the container. This position is also valid for the container flus h probe.
The assembly sheet in chapter 8 includes all the inf ormation required for installation.
Installation in Pipelines
The container probes can be installed in pipelines with a nominal
width ≥ 200 mm using an adapter flange. Please observe the position and orientation of the container probe (see the technical
drawings in chapters 8.4.7 and 8.5.6 Installation Situation in Pipelines).

Chapter 4 Getting Started
Connection of the flushing pipes
The container probe with flushing device consists of two flushing
devices with a 3/8 inch inner thread (DIN ISO 228-1). The flushing
connections are subsequently sealed to this thread. A sealing to
the probe cover is not permitted, for example with silicone.
Flush Parameters (only for container flush probe)
The degree of deposition or incrustation is essential for the flush
parameters, i.e. flush frequency and duration. The flush parameters have to be adapted to the product and the process.
The following independent flushing parameters for products and
processes have to be observed:
Flush solution water, condensation
Temperature of
flush solution
Pressure
Fittings 2 x 3/8 inch female screw thread
Supply pipe
Independent flushing parameters product and process, typical
starting rates:
Interval every 2 hours
Duration 12 seconds
Temperature of

For measurements on the C-product the flushing intervals can be
considerably reduced, e.g. every 6 hours for 30 seconds.
Maximum 120 °C
≥ 3 bar, max. 8 bar
(DIN ISO 228-1)
≥ 1/2 inch
average product temperature, mostly 65 ±5°C
Amount of water
DynFAS MW
The following is generally valid: the flushing devices can be
flushed simultaneously or in shifts. The flushing parameters are
valid for every flushing device.
Tip
The required flush duration has to take into account a possible
inertness of the system, e.g. valve openings. The flush supply
pipes have to be insulated well against heat to prevent that the
flush solution is initially colder.
The amount of water per flushing connector is approx. 0.8 l/sec at
a flushing pressure of 5 bars.

4.2.3 Installing the Control Unit
For installation of the control unit, please keep in mind:
¾ Install the control unit in the vicinity of the microwave probe,
keeping in mind the length of the HF cable. HF cables are
available in a length of 2, 4, 6 and 10 m; the standard cable
length are 2 or 4 m.
¾ Protect the instrument against vibrations.
¾ For instrument installation you should foresee a cutoff device to
allow easy and quick disconnection of the device from the
power supply.
¾ When installing the control unit on a crystallizer, use a distance
rail to minimize thermal radiation and heat conduction. See
Figure 4-3.
¾ When the control unit is set-up outdoors, it has to be protected
from direct sunshine and rain for example by means of an adequately large protective roof.

4.3 Connecting the Control Unit
4.3.1 Connecting the HF Cable
For the connection of the sensor with the control unit, you will
need a HF cable quad. Additionally, the flow cell requires an Nconnector.
Prerequisite for a proper measurement is the correct installation of
cables! Please keep in mind:
IMPORTANT
Make sure the cables do not get into contact with hot pipes over
the entire length (corrugated tube and single cable section after
splitting), e.g. direct contact with the device wall (not insulated).
This alone guarantees that all single cables are subject to the same ambient conditions and that the compensation of the cable
drift works properly.
Never bend HF cables! The bending radius should not be less than
100 mm. After installation, fix the cables with cable binders to
prevent the cable from slipping!
Connecting the Flow Cell
The HF-cable quad and the HF-connections on the control unit are
labeled. Connect the flow cell to the control unit as shown in Figure
4-4 and make sure that you only connect cables with equal labeling. The two connections on the flow cell are not labeled, the allocation of the cable connectors M-Tx and M-Rx is arbitrary. The cable plugs R-Tx and R-Mx are connector to the N-connector (shortcircuited).

IMPORTANT
When tightening the 21 mm screw nut, make sure that the connector is not twisted on the cable. If the connector is twisted relative to the cable, the shielding may get damaged and this could
result in mismatching and bad sealing.
Hand tighten all screwed connections of the HF cable (2 Nm = 0.2
kg/m)! Before tightening, carefully screw on the cable by hand.
Caution! Threaded joint jams easily.
Occasionally you should check if the screwed connection is still
properly tightened. If the installation is ex posed to vibrations, the
screwed connection may come loose and this may result in inaccurate measurements or corrosion of the connections.
As long as the cables are not connected, the coaxial sockets have
to be covered immediately with plastic caps and the cable connectors have to be protected by suitable provisions against moisture
and dirt.

4.3.2 Pin Configuration of the Connector Strip
Electrical shock hazard:
Disconnect power to rule out any contact with live parts during
installation and when servicing.
Turn off power supply before opening the instrument. NEVER work
on open and live instruments.
Temperature Signal Connection
A Pt 100 or a temperature current signal has to be connected to
current input 1 or 2 if temperature fluctuations occur in the product and if a temperature dependence of the phase or attenuation
measurement is likely to occur. The temperature sensor has to
measure the material temperature in the vicinity of the microwave
probe.
When taking the container probe into operation, connect the 4wire
cable of the Pt 100 to the connector strip of the control unit as
follows:

Chapter 5 Service Instructions
Chapter 5. Service Instructions
5.1 General Information
The control unit has no wearing parts or components requirin g any
special maintenance.
A malfunction of the measuring system is not always due to a defect in the instrument. Often the error is caused by incorrect operation, wrong installation, or irregularities in the product being
measured.
If a malfunction occurs, anyway, the measuring system helps you
to identify and eliminate errors by displaying error messages on
the LCD, indicating operator errors and defects of the electronics.
Usually, faulty modules of the control unit cannot be repaired but
have to be replaced. The microwave module is fixed with screws to
a shielding cover and must not be opened.
5.2 Wearing Parts
The control unit consists of no wearing parts and components that
need special attention.
The plastic rods of the Probes and the PTFE lining of the Flow Cell
can eventually experience abrasion depending on the material being measured. A lower to middle abrasion influences inconsiderably
the measurement or is compensated by calibration. Therefore, you
should check the wearing parts approximately every 2 years.
The plastic rods of the Probe and the lining of the Flow Cell can be
exchanged if abrasion is heavy. During excessive wear, the plastic
rods of the Probe and the lining of the Flow Cells can be exchanged. These Probes and the Flow cells have to be sent back to
the company. An on-site exchange is not possible.
5.3 Instrument Cleaning
Clean all system components using a moistened cloth. Do not use
any chemical cleaning agent. Parts coming into contact with the
product (during regular operation) can be cleaned with hot water,
taking into account the temperature limits (see chapter 6.2
Technical Data Sensors).
DynFAS MW

Chapter 5 Service Instructions
5.4 Battery
If the measuring system DynFAS MW is without power supply
(power failure or disconnected from mains), the system clock is
supplied with power by the Lithium battery on the CPU. The instrument works correctly even with empty battery, only measured
data which are output via one of the serial interfaces may become
useless as a result of the faulty date and time information.
The service life of the battery, even under continuous load, is at
least 8 years. To replace the battery, you have to disconnect the
instrument from mains.
Battery type: 3 Volt Lithium cell (round cell battery), type CR2032.
5.5 Fuse Replacement
The mains fuse of the DynFAS MW is located in the wall housing.
Replace the fuses only if the instrument is disconnected from
mains. Be sure that the new fuses match the rating specified.
Use only fuses with correct rating:
For CS-100:
Instrument version with 90 ... 265 V AC: 2.0 A slow-blow
Instrument version with 24 V AC/DC: 2.0 A slow-blow
For CH-200:
Instrument version with 90 ... 265 V AC: 2.0 A slow-blow
Instrument version with 24 V DC: 6.3 A slow-blow
Spare fuses must match the rating specified by the device manufacturer. Short-circuiting or manipulation is not permitted.
