Smokeless Flares
Smokeless flares incinerate flammable hazardous vent gas with the assistance of supplemental high-velocity air or steam to prevent the formation of soot or smoke. Excessive injection of air or steam reduces combustion efficiency, resulting in the release of hazardous VOC gases. Meanwhile, inadequate injection of air or steam results in the formation of undesirable soot and smoke. Although modern flares are designed for high flow rates associated with an emergency condition, they most commonly operate at high-turn-down, low-flow rates, making it challenging for the flare to operate at optimal combustion efficiency.
Pilot Monitor
Flammable vent gases are ignited by a pilot flame when released into the atmosphere by refineries, natural gas processing plants, and petrochemical plants. The proper incineration of these gases is a critical safety and environmental concern. Therefore, it is essential to confirm that the pilot is lit at all times. Monitoring via a thermocouple is common, however, failures frequently occur and replacements can require costly process shutdowns. Remote sensing IR technology (PM) is the superior alternative.
Flame Intensity Monitors
Williamson Flame Intensity Monitors (FI) are the single-wavelength sensors of choice for a variety of flare applications where the more sophisticated dual-wavelength flare products are not appropriate or are not required.
Some materials can be difficult or near impossible to measure with precision using single-wavelength or ratio pyrometers because of their complex emissivity characteristics. These types of materials are called non-greybody materials and their emissivity varies with wavelength.
Multi-wavelength pyrometers use application specific algorithms to characterize infrared energy and emissivity across the measured wavelengths to accurately calculate both the actual temperature and emissivity of these complex non-greybody materials.

An Approach to Detecting Writing Styles Based on Clustering Techniques
Authors:
-Devkinandan Jagtap
-Shweta Ambekar
-Harshit Singh
-Nakul Sharma (Assistant Professor)
Institution:
VIIT Pune, India
Abstract:
This paper proposes a system to differentiate between human-generated and AI-generated texts using stylometric analysis. The system analyzes text files and classifies writing styles by employing various clustering algorithms, such as k-means, k-means++, hierarchical, and DBSCAN. The effectiveness of these algorithms is measured using silhouette scores. The system successfully identifies distinct writing styles within documents, demonstrating its potential for plagiarism detection.
Introduction:
Stylometry, the study of linguistic and structural features in texts, is used for tasks like plagiarism detection, genre separation, and author verification. This paper leverages stylometric analysis to identify different writing styles and improve plagiarism detection methods.
Methodology:
The system includes data collection, preprocessing, feature extraction, dimensional reduction, machine learning models for clustering, and performance comparison using silhouette scores. Feature extraction focuses on lexical features, vocabulary richness, and readability scores. The study uses a small dataset of texts from various authors and employs algorithms like k-means, k-means++, hierarchical clustering, and DBSCAN for clustering.
Results:
Experiments show that the system effectively identifies writing styles, with silhouette scores indicating reasonable to strong clustering when k=2. As the number of clusters increases, the silhouette scores decrease, indicating a drop in accuracy. K-means and k-means++ perform similarly, while hierarchical clustering is less optimized.
Conclusion and Future Work:
The system works well for distinguishing writing styles with two clusters but becomes less accurate as the number of clusters increases. Future research could focus on adding more parameters and optimizing the methodology to improve accuracy with higher cluster values. This system can enhance existing plagiarism detection tools, especially in academic settings.

Drive Coils
Provide power to maintain oscillations at constant amplitude. Mounted on the mass bars,
the coils provide motive force and keep the “pendulum” running, even in applications
with highly dampening fluid flows. Straddling the parallel mass bars, the coils provide
equal force to both for a totally symmetrical drive of the overall mechanism.
Measurement Tubes
The part of the meter where the measurement takes place. The
measurement tubes within a Rheonik mass flow meter are semi-circular. A
long radius (compared to the diameter of the tubes) accentuates the bend
and deflection of the tube to provide “macro motions” and provides high
resolution time measurements for reliable flow determination. Furthermore,
the completely semi-circular geometry of the measurement tubes makes
them impervious to internal pressure changes and any measurement shifts
such changes can cause when the meter is in service.
Torsion Rods
Help energize and guide the oscillation. The torsion rods are the
heart of the Rheonik meter mechanism. As the mass bars are
driven and rotate, energy is loaded to and unloaded from the
torsion rods to provide smooth and “bump-free” motion on the
meter tubes. Also aiding in mechanism efficiency, the torsion
rods dramatically reduce energy loss and the need for high
energy drive across a wide range of application flow conditions.
Rheonik Omega
Mass Bars
Provide stability and support to the measurement tube
oscillation. Not only do the mass bars provide driving
force to the meter mechanism (like the pendulum of a
clock), their weight is designed to determine the most
advantageous base oscillation frequency of the flow meter.
For applications where Coriolis meters are to be installed
in close proximity, the mass weight is adjusted on each one
to suppress any localized cross-talk interference issues.
In/Out Tubes
Decouples measurement tubes from process line stress and misalignment. The in/
out tubes are collected close together in the center of the meter body to minimize
the effect of any stress and strain caused by pipeline connection misalignment on
meter performance. While not a substitute for proper installation technique, this
helps when meters are occasionally faced with real-world installation conditions.
All Rheonik sensors are constructed with standard size
measurement tubes and carry pressure ratings just like the
pipework around them. All are proof tested to 1.5 x their
maximum allowable operating pressure and all have a
burst pressure rating of 4 x their MAOP.
The electrical and electronic circuitry within Rheonik Omega
tube Coriolis sensor housings is certified as intrinsically safe.
Rheonik sensors can be safely deployed in any hazardous
environment.
Safety First
Technology
Pickup Coils
Two pick up coils work with precisely placed magnets to
provide a sinusoidal feedback waveform from each side of
the center of rotation of the meter mechanism.
When there is no flow, the waveforms are exactly 180 degrees
out of phase. The force of fluid flowing through the meter
causes the tubes to bend and deflect and as this happens,
the phase difference between the two signals changes. The
greater the mass flow rate, the greater the phase change.
High quality electronics measure the phase change by
measuring the time difference of the two signals and convert
it to mass flow.

Pressure Drop
This chart gives a general indication of
expected pressure drop when measuring
water flow across the full range of a
meter with standard pressure rating
stainless steel measuring tubes. Actual
pressure drop in operation is determined
by construction type, pressure rating of
the sensor tubes and the application fluid
characteristics. Contact Rheonik or your
local agent for pressure drop information
for your specific application conditions.
Only Rheonik offers a selection of calibration options to match application range for the best possible flow measurement
performance. Select for wide turndown, higher accuracy or low flow optimized performance from the Rheonik calibration portfolio
to maximize the value of your Rheonik Coriolis flow meter.
