Experience in using Aniuoba flow meters

I have never used an Anubaa, but I have used orifice plates; the principle is similar. When measuring steam, it is essential to install them properly and apply temperature and pressure compensation, which will yield much better results. With the correct range selected, the error should be minimal; after all, the two gauges aren’t installed on the same pipeline, and there are no issues reported from the process side... It is highly recommended to use integrated vortex flowmeters for measuring steam – they prove to be very useful……

I’m using Anubaa, but the steam flow fluctuates greatly, so I’m not sure whether it’s correct or not. Are there any brand recommendations for vortex flow meters?

Kroni’s integrated vortex flow meters are quite good; it seems that Yokogawa also offers vortex flow meters, and E+H ones are good as well. I do not recommend domestic vortex flow meters; of course, if it’s only for measurement purposes, it doesn’t really matter. It is best to purchase an integrated vortex flow meter with temperature and pressure compensation, as it is easy to install.

I use orifice plates to measure steam in large quantities; vortex flow meters are not reliable. Those available in China are cheap but of poor quality, while those imported are expensive. For differential pressure transmitters and pressure transducers, it’s better to choose high-quality imported ones. Aniu Ba also uses them, but I’ve heard that they have large errors at low flow rates.

There’s not much of a problem with Ainiuba; it depends on your requirements for precision. If you demand extremely high precision, then use it with caution. When using Anubaa to measure steam, proper installation is extremely important; to obtain accurate measurements, it is necessary to install it in accordance with the specified requirements. The straight sections before and after, the steam temperature, and the installation direction (downward, reverse) need to be taken into account. If it’s installed properly, there are usually no major issues. Additionally, Ainiuba manufacturers can produce integrated instruments with temperature and pressure compensation, which output the compensated (4-20) mA flow value directly.

To say a bit more, when installing Aniuoba, one must first consider the straight pipe sections; thereafter, it is necessary to determine whether to install it in the forward direction or in the reverse direction based on the steam temperature. The installation can also be done at a certain angle. If it is a split-type design, the layout of the pressure introduction piping is also very important. Judging from what you said, it’s not being used very well; it’s recommended to check these aspects first. The minimum length for the straight pipe section should be 8 units in front and 4 units behind; higher values may be required depending on the operating conditions, but 8 units in front and 4 units behind represents the minimum requirement. For integrated installation, if the actual temperature is above 200, it is recommended to install it in reverse, with Anubaa inserted from bottom to top. It can tilt 30 degrees to the left and 30 degrees to the right

Have you used Anewba flow meters?

Previously, I used orifice flow meters to measure air flow, but I didn’t maintain them much and didn’t know very much about them. Its measurement accuracy is not as high as that of an empty board. The requirements for straight pipe sections are also high.

Anubas are used a lot, and so are those for measuring steam. I’ve seen it in many factories; what’s your situation now?

The Aniuoba steam tester is pretty good. It gets clogged easily. . . If precision is not a major concern, then an orifice plate is the better choice – it requires almost no maintenance. If measurement is required, it is still recommended to use EJA’s integrated vortex street sensor
