2. Function
•The SolidFlow 2.0 is a measuring system which has been specially developed for measuring the quantity
of solids conveyed in pipelines.
•The sensor works with the latest microwave technology. It is only used in metallic pipelines. The special
integration of microwave technology together with the metallic pipeline creates a homogeneous
measurement field.
•The microwave radiation in the pipeline is reflected by the solid particles and received by the sensor.
The frequency and amplitude of the received signals are analysed.
•The frequency-selected evaluation system ensures that only moving particles are measured and
deposits are suppressed.
•SolidFlow 2.0 features active stratification compensation which increases measurement accuracy.

Operating Instructions
3. Safety
The SolidFlow 2.0 measuring system has a state of the art, reliable design. It was tested and found to be in a
perfectly safe condition when leaving the factory. Nevertheless, the system components may present dangers to
personnel and items if they are not operated correctly.
Therefore, the operating manual must be read in full and the safety instructions followed to the letter.
If the device is not used correctly for its intended purpose the manufacturer's liability and warranty will be void.
3.1 Normal use
•The measuring system may only be installed in metallic pipes to measure the medium passing through
them.
It is not suitable for any other use or measuring system modifications.
•Only genuine spare parts and accessories from SWR engineering may be used.
3.2 Identification of hazards
•Possible dangers when using the measuring system are highlighted in the operating instructions with
the following symbols:
Warning!
•This symbol is used in the operating manual to denote actions which, if not performed correctly may
result in death or injury.
Attention!
•This symbol is used in the operating manual to denote actions which
may result in danger to property.
3.3 Operational safety
•The measuring system may only be installed by trained, authorised personnel.
•During all maintenance, cleaning and inspection work on the pipelines or SolidFlow 2.0 components,
make sure that the system is in an unpressurised state.
•Switch off the power supply before performing any maintenance work, cleaning work or inspections on
the pipelines or the SolidFlow 2.0 components. See the instructions in the section entitled Maintenance
and care.
•The sensor must be taken out of the pipeline before any welding work is performed.
•The components and electrical connections must be inspected for damage at regular intervals. If any
signs of damage are found, they must be rectified before the devices are used again.

Operating Instructions
4. Mounting and installation
4.1 Typical components of the measurement point:
•Transmitter in the DIN rail housing or field housing
•Sensor mount for welding to the pipeline
•Sensor (union nut, spacer rings, sealing ring for adjusting to the wall thickness)
•Installation instructions
•C1- or C3-box
4.2 Required equipment
•Ø 20 mm-twist drill bit
•32 mm open-ended spanner for union nut
•Locking ring pliers (Ø 20 mm) to adjust the sensor to the wall thickness
4.3 Sensor installation
Proceed as follows to install the sensor:
•Decide on the installation position on the pipe. It should be installed from the top on horizontal or
angled pipelines.
•Note: Depending on the application, up to 3 sensors can be used on pipeline diameters larger than
200 mm, whereby the sensors must be mounted 120 mm apart and offset in relation to each other at an
angle of 120°.
•The distances apply to vertical and horizontal installations.
•Ensure that the measurement point is at an adequate distance from valves, manifolds, blowers and
bucket wheel feeders and other measurement ports such as those used for pressure and temperature
sensors, etc. (See Fig. 6)
Fig. 6: Minimum distances of the measurement point from pipe geometries and fittings
•On free-fall applications (for example, after screw conveyors or bucket wheel feeders), a drop height of
at least 300 mm is ideal.
7
Operating Instructions
•Weld the sensor mount to the pipe.
•Drill through the pipe through the sensor plug (Ø 20 mm). Ensure that the borehole is not angled so that
the sensor can be installed precisely at a later stage.
Attention!
•After drilling, it is essential to check whether the drill bit has caused any burrs on the borehole edges.
Any burrs on the pipe must be removed using a suitable tool. If the burrs are not removed they may
affect the sensor's calibration.
•If the sensor is not installed immediately insert a plug until it is installed (see also Fig. 7). The plug must
be inserted together with the seal, two sealing rings and the locking ring, and secured using the union
nut.
Use a 32 mm open-ended spanner to tighten the union nut.

•The sensor is supplied pre-assembled for the specified wall thickness or, if no wall thickness was
specified, to a wall thickness of 4 mm. Check again that it is correctly adjusted before installation
(see table). If necessary, the wall thickness must be remeasured using a depth gauge. The weld-on
socket is 93 mm long. It is important that the sensor does not project into the pipe. The sensor may be
up to 1 mm inside the pipe wall without this causing a measurement error.

The operator interface differs depending on the system design:
•DIN rail housing without display, operation via PC software
•Field housing with display, alternative operation via PC software
•One to three sensor system
First of all, the different system versions are described below. Following that, the basic operation of the
SolidFlow 2.0 system as a one sensor system is then described without going back over the different versions.
6.1 Differences between the DIN rail and field housing transmitter
The transmitter in the DIN rail housing is only a part of the functions available in the field housing.
The following overview clarifies the differences between the two versions.

Operating Instructions
6.3 PC interface
With the DIN rail version, communication with a laptop or PC is performed either on the terminals via an
RS 485 or at the front via an RS 232 interface. The field housing version is connected to the terminals via an
RS 485 interface or at the front via USB.
✔ The RS 485 connection is attached to the transmitter in the field housing at the ModBus A (+)
and ModBus B (-) terminals On the DIN rail version, these connections are
nos. 12 and 11, accordingly.
RS 485 is a bus connection; the ModBus address and the baud rate can be set on the device. Upon
delivery, the communication parameters are set to:
•ModBus address 1
•Baud rate 9600, 8, E,1
An RS 485 to USB adapter can be purchased from SWR.
✔ For the RS 232 connection to the DIN rail version, a special cable and USB converter
are supplied. USB uses a standard USB-A-B cable.
RS 232 and USB are point-to-point connections which are not bus-compatible. The ModBus address
and baud rate for the front connections cannot be changed and are always:
•ModBus address 1 (or the device answers to all addresses)
•Baud rate 9600, 8, E,1 - When connected to the PC for the first time, any interface drivers enclosed
with the transmitter must be installed.
After starting the software, the communication parameters must first be entered accordingly. These can
be found in the top left of the program window.
Communication is established by clicking on “Read device”. The acknowledgement message
“Parameter read in” is displayed. If an error message is displayed instead, check the
communication parameters and cable connections between the PC and the transmitter.
18
Operating Instructions
The edited data is transmitted to the transmitter via “Device program”.
Critical data concerning the ModBus communication and the calibration must be confirmed before the
parameters are transmitted to the transmitter:
✔ If, when saving the the parameters in the transmitter, the system calibration data
is changed, this action must be confirmed by checking “Overwrite calibration”.
✔ If, when saving the the parameters in the transmitter, the system interface parameters
are changed, this must be confirmed by checking the selection “Overwrite Baud/Addr.”.
In addition, with the PC software,
•the transmitter parameters can be saved in a file (Save configuration)
•the transmitter parameters can be loaded from a file (Load configuration)
•the transmitter parameters can be printed (Print configuration)
•the measured values can be logged in a data logger file (enter the file name and storage rate, and
activate the data logger on the online display)
The software language can be set by right-clicking the “Sprache/Language/Langue” field in the bottom
program line on “German/English/French”.
Protection against unauthorised use:
The PC interface does not have a password prompt as it is assumed that only authorised personnel will have
access to the PC and the software. However, the password to operate the display can be read and changed
in menu 7. System in 7.6. Password.

Operating Instructions
6.4 One or more sensor system
Up to three sensors can be connected to a transmitter if, for example, a larger flow section needs to be
illuminated. In the transmitter, the corresponding number of sensors will then be registered and a joint
average value will be calculated from their measurements.
The sensors are registered in menu 7 (System):
The existence of several sensors is shown on the online display and in the info area on the display.
Apart from registering the sensors and the resulting monitoring of several sensors by the transmitter, this
function has no effect on the operation and will not be described in any more depth.

Operating Instructions
2.5 Roping compensation Roping compensation sub-menuThe stratification compensation is used to compensate for measurement uncertainties which can
arise due to stratification. The sensors are supplied with an optimum default setting for normal
conveying conditions. If the measurement is influenced by unusual flow stratifications or stratification
shifts, the intensity of the compensation can be increased from 0 % to up to 100 %.
The sensor has two parameter sets for gravimetric and pneumatic conveying conditions. They should
be selected depending on the type of conveyance. The intensity adds part of the compensated
measurement to the uncompensated measurement: Both parts are weighted and calculated according to the selected intensity.
When using this function, we recommend only increasing the intensity in 10 % steps and to assess
the quality of the measurement results in each case.
A manual parameter set can be set and permanently stored by trained SWR personnel.
2.5.1 Conveyor Selection: AUS (OFF)/ GRV / PNE / MAN

Operating Instructions
7. Start-up procedure
7.1 Basic start-up
Upon delivery, the sensor is not calibrated to the product to be measured and must be parameterised when
started up. During the process, the mass flows measured by the sensor are assigned the display values and
output quantities required by the user.
The following points must first be checked:
•Check sensor is flush with the internal surface of the pipeline.
•The correct connection between the sensor and the transmitter.
•A warm-up time of approx. 5 minutes before starting calibration and after switching on the sensor's
power supply.
The expected flow rate must first be determined for the measurement point, and the required measuring
range and physical units must be entered in menu 1 (Measurement).
The system is then calibrated on at least two operating points (one empty measurement and one operating
point) in menu 2 (Calibration):
Min point While there is no mass flow, the 1st point is set to 0 and the
calibration for the zero point is performed.
Max point During normal conveyance, the 2nd point is set to a known flow rate and calibration is also performed.
The value can be corrected afterwards during weighing.
The device has thus performed its basic function and the measurements are displayed.
Additional support points If non-linearities occur when measuring with different flow rates, up to 5 support
points can be selected in menu 2 (Calibration). These support points can then
be calibrated with different flow rates.
7.2 Adjusting the measurement values
The system's additional functions can be set in the following menus:
Alarms Values for flow rate lower or upper limits can be set in menu 3 (Alarm)A sensor monitoring alarm can also be activated here.
Analogue output
The required measuring range is assigned a corresponding output value here
(4. . . 20 mA). Upper and lower limits of the permitted power and power in the
event of failure are set here. Power output can also be calibrated here.
Pulse output An internal totaliser function integrates the mass flow over time.
In menu 5 (Pulse output), the pulse output can be configured, so that the
system emits pulses corresponding to a defined conveyed mass.
Digital input In menu 6 (Digital input), the system's digital inputs can be assigned various
functions and their working direction.
System In menu 7 (System), functions such as selection of the menu language, the
number of connected sensors and their average, the display screen or ModBus
addressing and speed are summarised.
