Flow meter for venting flare gas
Thread Content
Experts, are there any good flow meters for torch venting systems? Ultrasonic flow meters are commonly used in such applications, but their prices are quite high :'( Are there any other types available?
At this occasion, both temperature and pressure will change; the pressure is quite low, and the gas composition is also variable. Therefore, it is difficult to measure accurately. Ultrasonic waves are mostly used, and special brands such as GE are required. I will also listen to this.
I remember working on a torch project that required very low pressure loss, and a vortex flow meter was chosen for that purpose.
You could consider the Weiliba flow meter; it’s also relatively easy to install. Our company uses VeriBa flow meters, and their performance is quite good
We have also installed ultrasonic (LUMMUS) systems, which are very accurate. But we have discussed the \"optical\" option; I heard that it is widely used in the United States, so you might want to look into it
I saw in the descriptions of thermal gas mass flow meters that they can be used to measure flare gas; I’m not sure about their application in production environments, and how does their price compare to that of ultrasonic flow meters? Please give me your advice
As far as I know, GE’s ultrasonic method provides the best measurement results for this application; followed by thermal conductivity methods and FCI methods. There are other methods as well, but they do not offer the same level of accuracy as the two mentioned above. For reference only
The price is definitely higher for ultrasonic models; thermal models can also be used for measurement, but they are certainly not as effective as ultrasonic ones； The main companies that use ultrasound for flare gas measurement are GE, Fluenta, and Sick
Currently, Bituba’s plug-in differential pressure flow meters are beginning to replace those made by GE in use for flare gas. Those who are interested can contact Manager Zhou at 18862332475; calling the company directly offers no advantages.
Monitoring the flow rate of vent flare gas has always been a challenge; due to the complex operating conditions on site, large fluctuations in flow rate, and changes in the composition of the medium, conventional methods are not effective. Gas ultrasonic waves are currently the best method for measurement. If the requirements for measurement accuracy are not very high and cost is a significant consideration, a thermal mass flow meter can be chosen. It is better to choose imported high-end brands; thermal flowmeters from ordinary brands do not perform well in practical applications, as the readings deviate significantly from the actual values and are unstable. Therefore, even among flowmeters of the same type, there can be significant differences in their performance, so careful consideration is necessary when making a choice.
