Coking feedwater flow meter
Thread Content
There is no flow before 40 tons at the beginning of water supply, making it difficult to control the water supply. (The flow meter is of DN350 type, a differential pressure flow meter with a range of 0–400 tons per hour.) Is it a problem with the flow meter? What about the other flow meters used for coking feedwater?
With such a large range, it’s normal not to be able to see the reading
A differential pressure flow meter with a range of 0–400 tons per hour; the selected model is too large, and as the flow rate is low, the flow meter often fails to display any reading.
My workshop is also this big, and it can be displayed
It’s hard to decide; the flow rate is very low at the beginning of water supply, while it’s high later on
