The double-headed snake in the piping system
Thread Content
Connect a DN300 branch pipe from the off-site ductwork; after the shut-off valve, the diameter is reduced to DN100, and then there is a flow meter for accounting purposes. The flow meter is followed by a DN250 reducer, leading to various workshops. What kind of amazing move is this?
When selecting a flow meter, factors such as accuracy requirements and pipe flow velocity must be taken into account, as well as economic considerations. Generally, mass flow meters have small diameters; if their diameter is the same as that of the main pipeline, it will result in higher investment costs. . . . .
For connecting to various workshops, should it be a velocity-type or differential pressure type? If straight pipe sections are not taken into account, might it be completely useless?
The diameter of the flow meter is only about 1/3 of the main pipe’s diameter; the difference is quite large.
The diameter of the flow meter is determined by the flow rate you choose.
I am in charge of those with a capacity of 100, and the flow meters have a capacity of 25; my main concerns are the accuracy of the flow meters and their cost-effectiveness.
