Looking for recommendations for domestic Anubaa flow meter manufacturers
Thread Content
This post was last edited by Xin You Meng Hu on 2018-6-12 at 10:08. Has anyone in this forum used the Aniuoba flow meter? For measuring air flow in wind tunnels. I asked Ross Monte about this before, and the price was way too high – a unit with a 600 cross-section costs tens of thousands of dollars. Are there any domestic brands you can recommend? Also, aren’t Ba-type products not very suitable for conditions with low flow rates, such as when the wind speed is below 5 m/s? For something like the Aoniuba 600 cross-section, I think the lower measurement limit is around 10 m/s, while the upper limit is quite high.
When people talk about Aoniuba, they mean Rosemount; other manufacturers use various names for it
The answer above is correct; Rosemount devices are called Anubas, while ABB devices are called Pitobas – they’re also known as pitot tubes. All of these are types of measurement devices that require a clean medium; otherwise, if the small holes inside get blocked, the readings will be inaccurate. The speed of an aircraft is measured using a pitot tube, as there have been instances where icing led to stalling and the aircraft crashing.
A pitot tube measures a point, while an anemometer measures a line; therefore their prices are definitely different. There are countless domestic options, but only through proper calculation and design can they be utilized effectively.
For large-diameter air flow meters, you can use our plug-in thermal mass flow meters, which allow for the direct measurement of volumetric flow rate under standard conditions, without the need for temperature or pressure compensation – what a convenience. The Aoniuba also requires a differential pressure transmitter; if the differential pressure value is too low, there will be no signal at all. Thank you
Yes, for the same type of measurement instruments, there is a huge difference between domestic products and those from Rosemount. So I’m wondering if among all these numerous options, there are any that are relatively superior, haha. The manufacturer suggested using domestic components for the sensors and Rosemount transmitters; is this a good approach? What do you mean by computational design as mentioned here?
That’s the case; fortunately, I still have around 200 PA here, so it’s still usable.
After all, a pitot tube measures only one point; considering issues such as airflow stratification and uniformity, the results obtained using it are not very satisfactory.
ABB’s device features a tube with many small openings; it measures a line, not a point, and operates on the principle of a pitot tube. Also, please reply to the other floors. If the measurement of the original sample is inaccurate, what’s the use of having highly precise measuring instruments?
