2.2.2 Communication between sender/receiver units and control unit
Standard version
The two sender/receiver units work as master and slave. The master FLSE has a second
interface to be able to completely separate communication to the slave FLSE and to the
MCU. The master triggers the slave and controls measurement. The MCU can request the
measured values from the master units independently of the measuring cycle
(asynchronous).
For the cabling, the junction box used to separate the interfaces has to be installed on the
master FLSE. The junction box is optional for FLOWSIC100 types PR and S (for longer cable
lengths).

Product Description
Bus version with several measuring systems connected
Fig. 3 Bus connection FLSE100 - MCU (2 sensor pairs)
With the bus version, two autonomous measuring paths (2 x 2 FLSE100) can be connected
to a control unit MCU for 2-path-measurement. The MCU computes both measuring paths
to one measuring result.
● For bus wiring, the set termination set at the factory must be deactivated in
those system components not at the line end (see Service Manual Section
3.1).
● Other sensor types (e.g. sensor for dust measurement) can also be connected to the MCU.

2.2.3 Functional principle
The FLOWSIC100 gas flow rate measuring devices operate according to the principle of
ultrasonic transit time difference measurement. Sender/receiver units are mounted on
both sides of a duct/pipeline at a certain angle to the gas flow (
These sender/receiver units contain piezoelectric ultrasonic transducers that function
alternately as senders and receivers. The sound pulses are emitted at an angle to the
flow direction of the gas. Depending on the angle and the gas flow rate v, the transit time
of the respective sound direction varies as a result of certain "acceleration and braking
effects" (formulas 2.1 and 2.2). The higher the gas flow rate and the smaller the angle to
the flow direction are, the higher the difference in the transit times of the sound pulses.
Gas flow rate v is calculated from the difference between both transit times, independent
of the sound velocity value. Therefore changes in the sound velocity caused by pressure or
temperature fluctuations do not affect the calculated gas flow rate with this method of
measurement.

Calculating the gas flow rate
Measuring path L is equal to the active measuring path, that is, the area through which the
gas flows. Given measuring path L, sound velocity c, and angle of inclination between the
sound and flow direction, the sound transit time in the direction of the gas flow (forward
direction) when the signal is transmitted can be expressed as:
(2.1)
Against the gas flow (backward direction):
(2.2)
After the resolution to v:
Apart from the two measured transit times, this relation only contains the active measuring
path and the angle of inclination as constants.

Sound velocity
Sound velocity c can be calculated by resolving formulas 2.1 and
2.2.
(2.4)
Based on the dependencies in formulas 2.5 and 2.7, the sound velocity can be used to
determine the gas temperature and for diagnosis purposes.
(2.5)
Calculating the gas temperature
Since the sound velocity is dependent on the temperature, the gas temperature can also
be calculated from the transit times (by resolving formulas 2.4 and 2.5 to derive
).
(2.6)
Formula 2.6 shows that, in addition to the measured transit times, the square of the values
of L and the standard velocity are included in the calculation.
This means precise temperature measurement is only possible when the gas
composition is constant, measuring path L has been measured extremely
accurately and a calibration has been carried out (see Section
p. 151, 4.3.6).
Determining the volume flow
The volume flow in operating state is computed using the geometric constants of the duct.
The process parameters pressure, temperature and moisture content are required to
calculate the volume flow in the standard state. A detailed description is provided in
Section § 2.4, page 44.
Path compensation
When the FLOWSIC100 is operated with a 2-path configuration, the device runs with an
integrated algorithm for automatic "path compensation".
During trouble-free operation, gas and sound velocity relations between both measuring
paths are recorded and saved. Should one path then fail, the system can replace invalid
measured values from the failed path with theoretical values based on the "learned" path
relations. The system signals "Maintenance request" status at the same time.
This means a single path can be compensated temporarily and measurement continued
with a slightly higher uncertainty until the malfunction has been cleared.

cooling air so that the duct probe can be selected with regard to type of material (steel,
titanium) and the transducer type (with/without internal cooling)
● Gas composition (corrosive / slightly corrosive or not corrosive)
The duct probe and transducers are selected on the basis of their resistance to corrosion (probe made from stainless steel / titanium, transducers made from titanium /
hastelloy)
● Duct diameter, sound dampening, dust content
The transducers are selected on the basis of the required transmitter power (medium
power / high power)
● Dust properties
Decide whether purged sender/receiver units need to be used (prevention of contamination with very sticky dust).
● Wall and insulation thickness of the gas duct
Selection of the duct probe and flange with tube according to the nominal length
(graded standard lengths). Other lengths can be supplied on request.
● Assembly type
On two sides, each with a sender/receiver unit on the opposite duct walls, or on one
side with one sender/receiver unit (as measuring probe version)
● Flange size
Small or large flange dimensions
(pitch diameter of the fixing holes 75 mm, 100 mm or 114 mm)
● Internal duct pressure
Pressure resistant versions must be used with pressures above 100 mbar (see OI
FLOWSIC100 PROCESS)
● Certification requirements
Selection after performance tests for emission measuring.

2.3.1.1 Standard sender/receiver units
A special transducer design makes it possible to use these sender/receiver units without
cooling by external purge air even with higher gas temperatures. A purge air unit is
therefore not necessary. The advantages are:
● Lower expense for mounting and installation
● Easier maintenance
● Lower operating costs.
For these reasons, standard sender/receiver units should be used where possible.
Product Description
Duct probe
● The types FLSE100-M, H and PR are intended for use with gas
temperatures up to max. 260
°C. The types FLSE100-SA and SD are
intended for use up to 150°C.
● The measuring system FLOWSIC100 S contains one sender/receiver
unit FLSE100-SA and FLSE100-SD and one connection cable between
the sender/receiver units.
● The type FLSE100-SA has no electronics unit. Communication to the
FLSE100-SD as master (which communicates with the MCU control
unit) runs via an analog connection cable (fixed length: 3m). Install one
FLSE100-SA and one FLSE100-SD per sampling point (1-path configuration).
● Fit the sender/receiver units at an angle of 60° to the flow direction for
dust concentrations > 1 g/m³ (only applicable for FLSE100-H, H-AC, PH
and PH-S). The downstream sender/receiver unit (B in
p. 15, Fig. 4) has
to be equipped with an impact protector.

2.3.1.2 Sender/receiver units with internal cooling
The types FLSE100-MAC and HAC can be used for gas temperatures up to maximum
450°C when fitted with internal cooling for the ultrasonic transducers. A control unit with
integrated filter and blower supplies the cooling air (
The advantages over the purged versions are:
● Lower costs for installation and operation.
● No flow of cooling air into the measured medium, therefore no direct influence on gas
flow and flow rate.
● Lower risk of dropping below the dew point with condensate on the probe head.
Fit the sender/receiver units at an angle of 60° to the flow direction for dust
concentrations > 1 g/m³ (only applicable for FLSE100-HAC). The downstream sender/receiver unit (B in Fig. 4, page 15) must be equipped with an
impact protector.
NOTICE:
Wet or sticky dust can cause strong contamination of the transducer and
disrupt the measuring function. In this case, the cooling air control option, Part
No. 2050814, should be used on device versions with internal cooling (M-AC
and H-AC). Use an external device version when necessary.

2.3.1.3 Purged sender/receiver units
Fig. 13 FLSE100-PM, PH, PHS
These sender/receiver units are intended only for use with wet and sticky dust when the
transducer surface is in high danger of contamination. Purge air is supplied by a purge air
unit to keep the active transducer surface clean and therefore protect against
contamination (
p. 43, 2.3.9). The purge air flow is optimized to maximize the directivity of
the ultrasound beam.
An integrated temperature sensor records the transducer temperature which can then be
displayed in SOPAS ET.
See the Application Range Table on page 21 for limitations of use
For dust concentrations > 1 g/m³, install the sender/receiver units at an
angle of 60° to the flow direction (only applicable for FLSE100-PH and
PHS). The downstream sender/receiver unit (B in
p. 15, Fig. 4) has to be
equipped with an impact protector.
At low gas temperatures, the purge air supply can cause the temperature to
drop below the dew point. To minimize the possible corrosion on the probe
head (for example, due to acid formation with corrosive gas compositions),
duct probes with a nominal length greater than that actually required for
the flanges with tube must be selected for temperatures between 150
and 200
350 mm
°C (for example, if the nominal length of the flange with tube is
a duct probe with a nominal length of 550 mm should be
°C
used). The purge air is then heated by the gas temperature in the probe
tube which minimizes temperature drops below the dew point.

2.3.2 Flange with tube
The sender/receiver units are mounted in flanges with tube available in graded nominal
lengths, different steel types and pitch diameters.
Selection of a flange with tube depends on:
● Installation angle and wall and insulation thickness of duct wall
Determining the nominal length (Assembly and Installation Chapter,
● Type of sender/receiver unit
Pitch diameter of flange, pipe diameter
● Duct material
Steel type
