- eh.digital/2PuPWRw - Illustration of the ultrasonic flow measuring principle.
Using ultrasonic waves, the flow volume of a wide variety of gases and liquids can be measured reliably - independent of electrical conductivity, pressure, temperature or viscosity.
Endress+Hauser's ultrasonic flowmeters provide a versatile and economical flow measurement of gases and liquids up to a nominal diameter DN 4000. Inline ultrasonic sensors are used in applications that require traceable and guaranteed accuracy. Clamp-on ultrasonic sensors are installed on the outer wall of the pipe and thus also enable temporary measurements or a retrofitting.

I can't thank this channel enough for these videos which allow us to learn about things without even visiting a plant. Thank you Sir.
Saw this video in a lecture and was really impressed at both the amazing graphics and really clear explanation, thank you!!
Very informative and well made video... while unrelated, it does give me a *_much_* greater understanding of how the ultrasonic wind speed/direction portion of my WeatherHawk 621 solid-state weather station works with your great visualization... *thanks !!!*
I love your videos! They are very clear, the visuals are great, and they are very informative. Thank you educating us all!

Buenas tardes. El medidor ultrasonico es dependiente de la turbulencia de flujo?? es decir; con flujo turbulento el medidor mantiene su precisión del volumen del fluido?
Please contact the Endress+Hauser sales center next to you. They will be happy to help you.
nice...
Many thanks for all videos.
Is it possible to create one video that covers the application of each flow and pressure gauging device, like which one is suitable for each particular application? also if videos incorporate the simplest version of an algebraic equation that relates flow/temp with the depending variable. transit time for instance in ultrasonic flow meter.
@Zeeshan Uddin, we deliberately did not include equations in our animations, as these videos want to give a very general explanation of the respective measuring principles. Creating one video explaining which instrument is applicable for which
application would result in a very long and very complicated video. Therefore we have no such plans. But we have quite a few nice tools which help you to select the right device. Check out our website or contact your local sales office. www.endress.com/en
alguien sabe que programa se utiliza para realizar la simulación,..
endress videos help us to understand measurement system
I enjoyed the video. I have a question.
Looking at the path that ultrasound crosses, it seems to pierce the wall twice in the middle. By the way, can ultrasound penetrate a blocked wall?
My experiment showed that ultrasound couldn't penetrate the wall.
So I wonder if ultrasound can pass through obstacles.
Thank you for your question. This animation features both ultrasonic technologies - inline and clamp-on. In the case of clamp-on technology and a two-path installation (as shown in the animation), the signal is reflected off the inner pipe wall and directed to the other sensor. In this process, part of the signal is lost due to penetration into the pipe wall (not visible in this animation). However, penetration into the pipe wall only occurs where the sensors are positioned in order to send and receive the ultrasonic signals.

Please make a video on LVDT and RVDT
You would have mentioned about the sonic velocity, temperature sensor inside also. Missed it.
Trying to learn about this method of metering..can you help?
🔥🔥🔥🔥

Hi
As far as I know, Endress+Hauser doesn't have the V-cone flow meter in their portfolio and therefor no 3D-animation..cheers..ursusbear1
Tanque sir
can i download this videos?
Does it need to be calibrated for a specific density first?
The measuring principle is generally independent of the fluid density, however the density correlates to the sound velocity of the fluid. This will effect the positioning of the clamp-on meter impacting the accuracy.
For inline process meters changing density has no effect on performance. So, the meter does not need to be calibrated with a specific density fluid for process measurement. However for “high accuracy” inline meters used for billing (custody transfer) they are often calibrated on specific density oils to improve performance with changing flow profile.

Thank you for the detailed explanation!
Add english subtitle..then it will be easily understand to any people
How to calibrate ultrasonic flow sensor?
Please get in touch with your local Endress+Hauser contact: eh.digital/3nVvdH7. They are happy to assist you.
Are the sensors in physical contact with the liquid
It depends if you are using an ultrasonic clamp on meter such as the proline Prosonic 93 the sensors are NOT in contact with the liquid. If you are using an inline meter such as the Proline Prosonic B 200 the sensors are in contact with the liquid.
does this work if the flow doesn't cover the whole cross section of the conduit ?
From one of our Product Managers: The meter will still provide a measurement in a partially filled pipe, but it won’t hold to the accuracy spec. The volumetric flow rate is established by combining all the flow velocities determined by the transducers, along with the cross-sectional area of the meter body.
@@seanbeeker4980 : can I get more information somewhere? I am working on a project requiring measurement through a pipe but a wider range and we have several scenarios requiring shallow flow. Can you recommend a meter for that please. Thanks
goood nice
wait.. since the sensors are inclined .. how does the signal both in upstream and downstream reach the other sensors?
By design of the sensors and proper positioning it is made sure the sound beam always hits the opposite sensor.
is it because the wave speed is much much much much faster than the water speed?
Mainly it is because of emission angle, deflection when entering material with different density (pipe wall, fluid, pipe wall) and corresponding positioning of the sensor set.
is this possible for the tube of 1mm

can you tell me the names of the product and the companies name
The animation was produced by Endress+Hauser. It explains the measuring principle in general and does not refer to any specific product. You can find our ultrasonic product portfolio on our website. www.endress.com/en/Field-instruments-overview/Flow-measurement-product-overview
Can we communicate to meter via Modbus ?
Thank you for your question. Whether Modbus is supported by an ultrasonic flowmeter depends on the device selection. Please contact our Sales Center near you (www.endress.com/en/contact). They will be happy to look at your specific case.
what is the accuracy of this flowmeter ??
Please check the product finder to discover all our ultrasonic flowmeters and check their specs at a glance. eh.digital/3lDqqHP Additional information about the devices can be found here: eh.digital/39m67ZE
how to reduce turbulence ?
Turbulences can be miminized by optimized installation of your flowmeter. For recommendations check the technical information of your flowmeter manufacturer.
Endress+Hauser thanks for your reply but in a large system where piping can't be alter a bit and have non linearity how can it be improve...and flow rate difference of 0.6 between two ends,is it significant?
Yes, you can use a flow conditioner or you can install the meter further away from what is causing the flow disturbance.
Impressing, but subtitle please?
Subtitle s in English please
