Selection issues for torch flowmeters
Thread Content
Now, as environmental inspections become increasingly stringent, torch emissions are also included in these inspections, and it is required to keep track of the emissions from torches; therefore, flow meters need to be installed. I would like to know how people apply these devices in practice, and I hope everyone can share their ideas to come up with better solutions.
No way, it’s been in use for decades already – and they still want to gather more ideas.
The flow rate of flare gas varies greatly; a large range ratio is required, and a thermal type will suffice
There isn’t much dust and the temperature isn’t high; using a thermal type is the most cost-effective option. If that doesn’t work, then use a P-type... weiluox666888li
For torches, the best options are generally gas ultrasonic flowmeters; for imported ones, GE is a reputable brand. There aren’t many high-quality domestic options available at present, so it’s necessary to select the appropriate model based on the actual requirements
Thermal mass, ultrasonic, Pitot tube and other flow meters – choose according to your needs!
If the modifications are required as a result of environmental inspections, the selection of instruments in such cases must take into account the conditions on site during construction. Generally, the diameter of the flare gas pipes is relatively large, which makes hot work more difficult; it is recommended to implement isolation measures and gas displacement procedures before using thermal flow meters； Bar-type flowmeters may not achieve the required pressure difference for proper operation; the system after the flare is essentially just up to the flare tip, so bar-type flowmeters should be used with caution
