A flow meter is a device used to measure the volume or mass of a gas or liquid. Flow meters are referred to by many names, such as flow gauge, flow indicator, liquid meter, flow rate sensor, etc. depending on the particular industry. However, they all measure flow.
This article provides a brief yet concise idea about flow meters and the pertinent terms related to them. This article classifies the different types of flowmeters and cites the different devices for measurement under these categories. Also, this article speaks about the major five classes of flowmeters viz. differential pressure, velocity, positive displacement, mass, and open channel.
Pressure measurement is the analysis of an applied force by a fluid on a surface. Pressure is typically measured in units of force per unit of surface area. Many techniques have been developed for the measurement of pressure and vacuum. Instruments used to measure and display pressure in an integral unit are called pressure gauges or vacuum gauges

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

4. The most diverse substances are transported
and distributed in piping system in every
single day they may include solvents ,
chemicals oil&gas , drinking water , fruit
juices , slurries etc
The fluid flowing through pipe often have
completely different properties consequintly
there are different principles and different
flow measuring devices
5. A simple instrument made by inserting drilled
orifice plate between two pipe flanges and
arranging suitable pressure connection.
An orifice plate is thin plate with a hole in
middle which helps to measure flow rate.

9. Some three years ago swiss mathematician
and physicsts danel bernulli discover direct
relationship between pressure and speed of
fluid flowing in a pipe. italian physicsts
batista venturi also perform experiment on
flow and in 1797 he build first flow meter
known venturi tube
10.
11. A meter consist of short converging pipe
relatively longer pipe diverging with suitable
pressure differential measurement.
When fluid passes through converging side
its velocity increases maximum at throat and
and become same after passing throat
12.

14.
15. Rotameter consist of tapered tube made by
glass or plastic with a float inside that is free
to move
A rotameter is device measure flow rate of
liquid and gas in a closed tube
It belongs to class of meters called variable
flow meter in which pressure drop remain
constant and flow varies directly with cross
sectional area
16.
17. When fluid enter from bottom it exert force
on float and float move up when gravitational
and force exerted by liquid become equal
equlibrium exist and float becomes stationary
then flow rate measure by graduation scale
on float
18.
19. Pitot tube is pressure measure instrument
used to measure fluid flow velocity.
Pitot tube measure local velocity at given
point in stream not average velocity in pipe.
20. When pitot tube placed in a pipe from which
fluid is flowing as pitot tube has two tubes
one with large diameter having holes which
measure static pressure . while fluid entering
small tube on striking become rest kinetic
energy converted into pressure energy
exerted a pressure called impact pressure the
difference in total pressure minus static
pressure give pressure difference which give
velocity of fluid by bernoullis equation.

24. Inference…
• There are many types of flowing fluids having different
properties and nature so different measuring instruments
require
• So flow meters as we discuss in this presentation their
accuracy and effeciency depend on nature of flowing
fluid
• But most comman flow meter used in chemical industries
is orifice meter which mainly measure flow of liquids and
gases
