idk why im even paying for school when I can learn it all online anyway, oh wait everything is online cause COVID so im really just paying for nothing.
This video has cleared my many doubts on orifice, venturi tube and venturi nozzles, the HD animation along with the name and year the scientist worked on flow measurement was added cheery topping on this explanation video, many thanks to the person who made this highly educated video, please keep on making video just like this on different parts too...
Thanks for the brilliant videos, im studying electrical and instrumentation control at trade school in australia and our teachers are completely useless, thanks mate
Note for myself. When we add a measurement tool: orifices, that creates turbulence. Hence we add a nozzle, or even better than that: we use a venturi meter instead, lessening the turbulence.
@joepipe101: Basically it is possible to work with a venturi solution in this case. But also a Pitot tube solution comes into consideration. To figure out the solution that fits best we need further information. Therefor please contact your local Endress+Hauser representative in Canada.
💖 This is an inspiration for ME !! Even I make "INSTRUMENTATION VIDEOS". I hope I can emulate your presentation skills. All the best for your future videos ☺
It measures the discharge/Volumetric flow rate of the fluid. But I can't say that the Volumetric flow rate would be same throughout the cross section of the pipe because at other points of the pipe we shall observe much less pressure drop/ pressure difference . Then why do we need these measurement devices ?
We'd kindly ask you to contact your local Endress+Hauser support. There you'll find best assistance for the tailored solution. The contact details can be found here: www.endress.com/en/contact
2009 ??????? I'm watching this video in 2022 and I still don't feel like I am watching something from stonage , way better than a silly indian video that starts with hallow friends and bugs rush into the video
Great works I really enjoyed every bit of this explanation.. Can you explain why differential pressure flow meters cannot measure mass flow rate directly thought they are dependent on the fluid's density. We know that change in the fluid's density will affect the meters readings then why it is not termed as mass flow meter and it is called volumetric flow meter.. Thanking you in advance...
+XyekiniX This depends on the type of diaphragma: Ceramic process isolating diaphragm. The ceramic measuring cell is based on the principle of a plate capacitor with an electrode on a meter body and a movable electrode on the interior of the diaphragm. Silicone oil or mineral oil are used as the standard filling oils for this measuring cell. A differential pressure (p1 ≠ p2) causes a corresponding deflection of both diaphragms. Both capacitance values are converted and are fed to the microprocessor of the transmitter as a digital signal. Metal process isolating diaphragm. The process isolating diaphragms are deflected on both sides by the acting pressures. A filling oil transfers the pressure to a resistance bridge (semi-conductor technology). The change in the bridge output voltage, which depends on the differential pressure, is measured and processed further.
Dear Mr Hagopian, we would be proud if you would use our videos in your course. Please contact our Sales Center near you (addresses.endress.com). They can provide you our measuring principle videos in several qualities. Please take care that you always have a reference to us.
