Abstract: the flow of compressed air flow measurement scheme analysis information produced by excellent flow meter, flow meter manufacturer to offer you the quotation.
Measurement of compressed air flowmeter
has a lot of, because of the difference of every enterprise production requirements, the flow of compressed air is also different, this paper put forward in view of the small flow of compressed air pipe flow measurement solutions, hoping to help the masses of users.
More flow meter manufacturers choose model price quote you are welcome to inquire, here is a small flow of compressed air flow measurement scheme analysis for details.
Measurement of compressed air flowmeter has a lot of, because of the difference of every enterprise production requirements, the flow of compressed air is also different, this paper put forward in view of the small flow of compressed air pipe flow measurement solutions, hoping to help the masses of users.
In view of the small flow of compressed air pipe flow measurement, there are mainly two kinds of schemes, one is to use the flow measurement threshold is low, span a wide range of thermal type gas mass flowmeter;
The second is to do the vortex flowmeter in reducing to meet the measurement requirements.
For example to illustrate it.
A user is (piping, zui small flow rate is 10 m3 / h, zui heavy traffic around 110 m3 / h.
Like this kind of condition by ordinary (vortex street flowmeter is never even measure effect, to make it, have to wake up with a start reducing measure effect, flow meter can be narrowed to DN25 calibre, 8 - the scope of its range can do
120 m3 / h。
Here I want to do a lengthy, vortex street not shock resistant, measuring the vibration of the compressed air is the main source of the compressor and blower, so when installing vortex street must far away from the compressor, blower vibration source, etc.
Compressor at the same time, has certain pulsating flow blower export more, its measure of vortex street is also influential.
To solve the problem of pulsating flow in addition to stay away from the compressor and blower, also can be set in compressor exit a buffer tank, install the vortex behind, general compound compressor system are designed.
If the scene too much vibration is not easy to install vortex street or want to better use of the flowmeter, can use a thermal type gas mass flowmeter, the scope of its range can reach 0.
700 m3 / h, said we should pay attention to here, hot type cabin temperature pressure compensation, shows the standard under the conditions of flow, flow unit is Nm3 / h, this is based on the use of pressure and temperature in the field to conversion.
Often contain a lot of water vapor in the compressed air, if the moisture is more, for not affect measuring precision need to install a strainer ahead of flowmeter.
Some people say that in addition to these two kinds of solution gas turbine flowmeter can measure small flow of compressed air, I personally don't recommend that users use the turbine, because the flow rate of the compressed air is not stable, traffic is very bother you let will cause the damage of impeller.
About the flow of compressed air measurement scheme if you have questions or have other ideas please feel free to discuss.
Flow meter manufacturer as speed meter and positive displacement meter, differential pressure meter, area meter professional manufacturer, has always insisted on developing new technology, new products.
Summarize the experiences of years production practice, the positive communication flow field at home and abroad, working to develop a variety of flow measurement products, forming scale, systematic and diversified pattern of production.
Looking forward to progress hand in hand with you.
Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
