If I understand well, your request is the precision we
can expect for sound speed meausrement and sound attenuation.

This value is dependant of your experimental setup,
electronics performances, and dimension measurement accuracy.

usually 1/100, we can expect 1/1000 m/s accuracy in ultrasonics speed
measurement with higth precaution procedure.

The attenuation accuracy depend on the same parameters
and also frequency use. For materials with higth
attenuation You can't perform the soound propagation
on big length, so your accuracy is limited.

Can you precise your application, please

absoption and speed of sound in milk.
: As with accuracy to measure of factor of absorption and speed of a sound in a liquid. For example milk.

This subject is interesting for me (especially wave sound in milk).
I'll be glad to get further information about applications of ultrasound in sound measurements in MILK.
Is someone manufacturing such equipment?
Thanks

Re: absoption and speed of sound in milk.
An associate of mine, Dr. N.D.Patel, has made a system specifically for acoustic velocity and
attenuation measurements.
He has done measurement with milk and it can measure one drop of milk in 50 drops of water.
Important is that velocity is also function of temperature and thus we can use comparator
measurement and we should be able to measure very accurately. There is quite difference in 1%,
2 %, Homo and lactose free milk. The system can measure with 50 picosec accuracy.
Dr. Patel's email is fallon@netcom.ca

Take a look at www.rhosonics.nl
They have equipment and sensors for in-line measurements.
The ultrasonic sensor has a build in temperature sensor
that is realy needed for high accuracy concentration measurements with temperature compensation.

Despite having managed to halve the weight of similar portable X-Ray generators available on the market (while continuing to provide the same power output), the SITEX CPSERIES generators feature a shutter, a laser pointer, a beryllium window, an aluminum filter and two integrated diaphragms (customized sizes are available upon request). Without compromising the robustness and reliability for which ICM products are renowned, the small size and light weight of the SITEX CPSERIES will radically change the way that you perform your RT inspections. And you will see a positive impact in terms of both quality and return on investment (ROI).
