Orifice flow meter upstream requirement
Witryna10 lis 2024 · Applications of Orifice Meter. Listed below are the two primary uses of an orifice meter: It is used to measure the flow rate of fluids in their single state (i.e. gaseous state or liquid state). It can … WitrynaA “honed run” is a complete piping assembly consisting of a manufactured fitting to hold the orifice plate and sufficient straight lengths of pipe upstream and downstream, the interior surfaces of that pipe machined (“honed”) to have a glass-smooth surface with precise and symmetrical dimensions.
