MaxxFlow HTC
Fall through measurement
of high mass flow rates
For measurement of high mass flow rates for dry solids from the exit of pre feeding devices,
e. g. screw conveyors, air slides, rotary valves, bucket elevators, etc.
● Most non-metallic solids can be measured
● Can be installed on round pipes or ducts
● No real upper limit of mass flow
● Maximum pressure 10 bar
● Dust tight
● No flow restrictions to the process flow (wear resistant ceramic liner)
● The mass flow measurement is independent of flow characteristics
● Maximum temperature, 12O °C
● Can be installed at an angle
● Small footprint, 220 mm (DN 100), 290 mm (DN 150), 310 mm (DN 200)
● No moving parts, hence no maintenance
The MaxxFlow HTC is specially developed for the flow measurement of dry bulk solids during high-volume throughput. Due to its completely open profile and its low installation height, the MaxxFlow HTC is especially suitable in situation in which it was previously only possible to use complicated or expensive mechanical solutions, e. g. impact plates or measuring chutes.
The installation of the MaxxFlow HTC takes place independently of the direction of the line (vertical/inclined), but always after mechanical conveyor elements,
e. g. rotary feeder, screw conveyors, air slides or chain conveyors.
After the conveyor, the material to be measured falls or slides through an inlet path and runs through the sensor. During the throughput, the MaxxFlow HTC records the material type and speed. Since the material falls from a constant height after emerging from the conveyor element, the speed of the product stream is accelerated, but is constant at the installation position of the sensor.
Due to this constant speed, the speed measurement does not need to be activated in every case, but can be calculated as a constant depending on the height of the fall. The mass flow is determined as follows:
Q (kg/s) = K (kg/m3) x v (m/s) x A (m2)
Through the input coupling of a high-frequency, electro-magnetic alternating field, a homogenous measuring field is generated in the measuring tube.
The measuring tube (interior tube of the sensor) consists of wear-resistant Al2O3 ceramics. Dry bulk solids inside the measuring field reduce the amplitude of the alternating field.
This leads to a measuring signal that is in proportion to the concentration of the dry bulk solids in the sensor (kg/m3).
If the material speed varies, for example due to a change in initial speed, then this can also be measured.
This takes place through a runtime measurement with the help of two additional electrodes behind the interior ceramics tube.

Advanced control scheme of doubly fed induction generator for wind turbine us...IJECEIAES
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

A review on techniques and modelling methodologies used for checking electrom...nooriasukmaningtyas
The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.
DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODELgerogepatton
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

measurement of dry bulk solids without any built-in in the
flow. Due to its independence from angle of the pipework
and its low installation height, the MaxxFlow HTC is
especially suitable in situation in which it was previously
only possible to use complicated or expensive mechanical
solutions, e. g. impact plates or measuring chutes.
The installation of the MaxxFlow HTC takes place
independently of the direction of the line (vertical/inclined),
but always after mechanical conveyor elements, e. g. rotary
feeder, screw conveyors, air slides or chain conveyors.
Function
After the conveyor, the material to be measured falls or
slides through an inlet path and runs through the sensor.
During the throughput, the MaxxFlow HTC records the
material density and speed. Since the material falls from
a constant height after emerging from the conveyor
element, the speed of the product stream is accelerated,
but is constant at the installation position of the sensor.
Due to this constant speed, the speed measurement
does not need to be activated in every case, but can be
calculated as a constant depending on the height of the
fall. The mass flow is determined as follows:
Q (kg/s) = K (kg/m3
) x v (m/s) x A (m2
)
Through the input coupling of a high-frequency, electro-
magnetic alternating field, a homogenous measuring field
is generated in the measuring tube.
The measuring tube (interior tube of the sensor) consists
of wear-resistant Al2
O3
ceramics. Dry bulk solids
inside the measuring field reduce the amplitude of the
alternating field. This leads to a measuring signal, behaves
with a system accuracy of 0.04 %, proportional to the
concentration of the bulk solids in the sensor (kg / m³).

If the material speed varies, for example due to a change in
initial speed, then this can also be measured.
This takes place through a runtime measurement with
the help of two additional electrodes behind the interior
ceramics tube.

3. System
A complete measuring station consists of these
components:
• Measuring feeder for installation in the conveyor line
• Transmitter MSE 300
The measuring feeder is available in sizes DN 70 mm,
DN 100 mm, DN 150 mm and DN 200 mm.
With the design in DN 70 mm, the connection flange
could be freely selected.
The transmitter is connected to the sensor using 4-wired,
shielded cable.
The maximum distance between measuring feeder and
transmitter is 300 m.
Calibration
The recording of the speed is in every case independent
of the type of the dry bulk solids that are to be measured,
since they can either be calculated or based on a runtime
measurement.
Thus the speed measurement requires no calibration.
This makes a new and simple type of calibration possible:
A material sample (approx. 10 liter = sensor volume) can
be poured into the sensor via a filling nozzle in the inlet
path above the sensor.
There is a knife-gate below the sensor that is closed for
the calibration. If the sensor is completely full, then the
measured density value must correspond to the bulk
density of the material.
This bulk density (set point) can simply be determined
as kg/m³ weight and entered in the evaluation unit
(full calibration). Even with large product flows, the
measurement is completely calibrated with a material
sample of only about 10 liter.
Material drop-tests using calibration points during a
running process are thus a thing of the past.
The handling of several tons of material as a reference
therefore is no longer necessary.

4. Configuration
For the configuration of the sensors, the knowledge of the
maximum volume flow is fundamentally important in order
to configure the measuring point in such a way that the dry
bulk solids can flow through the sensor unhindered and
the product flow is not influenced.
The diagrams in figure 1 and 2 shows the maximum
conveyable volume depending on material speed.
The sensor cross-section in all cases is filled to 50 %.
Example:
If the max. mass flow amounts to 80 t/h, and if the material
has a bulk density of 0.8 t/m3
, then the maximum volume
flow amounts to 100 m3
/h.
When using a MaxxFlow HTC DN 150 mm, a speed of
approx. 3 m/s would be necessary.
When using a MaxxFlow HTC DN 200 mm, a speed of
approx. 1.7 m/s will be required.
Figure 3 shows that for these speeds to be reached, an inlet
path of 0.5 respectively 0.15 m will be necessary between
the conveyor and the sensor.
Turndown and measuring range
Which sensor type is being used depends on the available
standing installation height and the turndown or the
desired measuring range.
The sensor itself has an installation height of 216 mm
(DN 70), 220 mm (DN 100 mm), 290 mm (DN 150 mm) or
310 mm (DN 200 mm).
To equip the measuring point from the above example with
a DN 150 mm sensor, an installation height of
500 mm + 290 mm = 790 mm would be necessary.
The turndown, i.e. the ratio between the end and the
beginning of the measuring range, amounts to 1:5 for all
MaxxFlow HTC sensors.
With regard to the example provided, it is possible to
measure with a MaxxFlow HTC DN 150 mm between
20 m3
/h and 100 m3
/h.

therefore no dead spots
• independent of the arrangement of the line
(vertical or inclined)
• simple refitting
• dust proof
• zero-contact measuring procedure (no mechanics)

A MaxxFlow HTC DN 200 mm can also be used for this
measuring task. Care must be taken that the angle for
the contractions of the inlet path at a height of 0.15 m
does not become too flat. The angle α (see figure 4) must
be at least 60° in order to guarantee a flawless product
flow. If the inlet path (height of fall) must be enlarged to
maintain the demand after an angle > 60°, then it must
be noted that the lower limit of the measuring range
moves upward.
If for example an inlet path of 0.3 m would become
necessary, then the speed would be approx. 2.5 m/s
and thus the maximum volume for a MaxxFlow HTC
DN 200 mm 150 m3
/h.
With a turndown of 1:5, the lower measuring range limit
would then be 30 m3
/h.
