The flow meter does not match the actual gas production volume; any advice?
Thread Content
1. What is the principle of a gas flow meter? 2. Recently, there was a pipeline whose flow rate was to be kept between 0 and 3000. However, when the flow rate was below 2000, it hardly showed any value, or the displayed value did not correspond to the actual amount of gas produced. I really couldn’t understand this at the time; the flow rates of other pipelines within the 2000 range were displayed normally, but not that one. Later, I looked up some information sporadically to see if the parameters could be changed. I need some advice. How to solve this so that the traffic volume is displayed accurately? Thank you very much
What is the range of the transmitter, and what type of flow meter is it?
It’s not that simple, right? It depends on whether the flow meter chosen is appropriate… I don’t know; I came here to learn
Dare you say what type of flow meter it is? ? ? Vortex street? Orifice plate? Quality? Then consider whether it is a temperature and pressure compensation issue, then consider whether it is a low-flow cutoff issue, and then consider whether it is an instrument selection issue
The flow meter really does require careful selection, as it involves issues related to the minimum flow rate and the detection principle. In your case, it might be due to an excessively low flow rate. All flow meters have a minimum detection range, and this range is determined based on the flow rate in m/s rather than the flow volume in m3/h; the minimum flow rate varies depending on the type of flow meter. Take a look at what you’re using, then calculate the flow rate to see if the flow rates below 2000 are all too low. Furthermore, saying that everything is fine except for this one issue is an unprofessional approach; we need to verify whether the other parameters are consistent in order to have a meaningful comparative analysis, such as diameter, medium, temperature, type of flow meter, installation location, and so on.
That’s too general of you; you don’t even know what types of flow meters exist
The reliability of gas flowmeter measurement is highly dependent on factors such as the selection of the flowmeter, parameter settings, whether there are significant deviations between the operating conditions and those specified during selection, and unit conversion. The original poster said only that, so we can only say it’s hard to tell on this matter.
Well said; to add, the medium pressure also needs to be confirmed. In essence, it is to determine whether the instantaneous flow rate of the medium under operating conditions falls within the range that the flow meter can measure properly; in other words, whether the flow velocity under those operating conditions is within the range that the flow meter is capable of measuring accurately.
Gas flow meter? What specific flow meter is it? Is there temperature and pressure compensation?
