What should be considered when installing a flow meter?
Thread Content
The flow meter used in our company is a tower-type flow meter, with a measurement range of 8000–15000 cubic meters per hour. It seems that there should be no shut-off valves or other obstacles within 5 meters in front of and 10 meters behind this flow meter, in order to avoid affecting its accuracy. I’m not sure if what I’m saying is correct (to be confirmed). But what should be taken into consideration during the actual installation? Please give me some advice! ! !
You’re right; there is such a rule: there must be no shut-off valves or other obstacles within 5 meters in front of and 10 meters behind the flow meter. Another point is that the reading panel of the flow meter must face the side where it is easier to read.
Our factory has used this type of flow meter before, and we have a basic understanding of it. Compared to annular chamber orifice flowmeters, this type of flowmeter generates greater resistance. If the gas purification is inadequate, the gap between the gas guide cone and the tube wall becomes smaller and smaller, which leads to flow distortion and frequent cleaning needs.
