Wow. This video is freaking amazing! Everything I've done for the past 5 weeks of my fluid mechanics lab makes sense on a new level.

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 is great! It's so much easier to understand these concepts when you can actually see them in action visibly. Thank you for making this video!

[@anilksingh650]

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...

Finally understood basic working of obstruction flow meter.. thanks a gazillion!!!

[@marytheraspberry3145]

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.

[@AsadPassionateEngineer]

💖 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 ☺

Excellent demo on differential pressure creating device.

[@shanu6478]

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 ?

[@endresshauser]

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

[@aravindhs9988]

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...

[@endresshauser]

@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.

[@Mech.Masters]

Pressure Gauges used in Hydraulic Machines have got a small hole of 1 mm dia, How does the gauge shows the correct value of pressure in system, there should be a pressure drop as it is also similar to orifice?

[@endresshauser]

If you are talking about a loss of pressure due to a change of pipe size, we are definitely not able to compensate for the pressure loss created by the friction of the pipe. What the pressure instument shows is the instantaneous pressure measurement at that single point.

[@karunmonnappa467]

thanks a lot for video. great animation

[@XyekiniX]

How does the sensor measure the diaphragm displacement?

[@endresshauser]

+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.

[@vishal6507]

Excellent video sir.

[@rhomis]

Thank you. I am going to us this video in the class I teach.

[@josephdominicer]

i wish my professors were this good!

[@MrFernandoBedoya]

In minute 4:15 you read (and listen): "With this measuring principle all liquids, gase or stea can be measured...." ¿How can I measure pressure of a gas with a venturi principle?

[@endresshauser]

For just measuring the pressure of a gas or other fluid you would install a pressure sensor - no need to consider a venturi. A venturi element generates a pressure drop with flowing fluid which allows to measure the flowrate when measuring the pressure differential up- and downstream.

[@hmmrmianmrehman6891]

Hello sir I have a Curie about the flow metre for liquid ammonia so please guide me about the flow meter which type of flow metre is suitable for liquid ammonia

[@endresshauser]

In general, liquid ammonia can be measured with dp-Flow. The correct selection of the flowmeter and its design depends on various application parameters and should be discussed with the Endress+Hauser sales office in your country. www.de.endress.com/en/country-language-chooser Thank you for your positive feedback and interest in Endress+Hauser instruments.
