mass flow meter symbol
In a volumetric flow meter the flow Q is equal to the cross-sectional area of the pipe A and the flowing fluids velocity v. 3 are referenced as such.
Mass vortex is ideal for steam and saturated steam applications but it can also measure gas and volumetric water.
. Piping can be made of various materials including metal and plastic. However when we are being specific then any of the specific symbol for the particular flow sensormeter can be used. - 3 - ANSIISA-51-2009 Preface informative This preface is included for information purposes and is not part of ANSIISA-51-2009.
Flowmeter smart coriolis mass pressure flow. The Coriolis measuring principle is used in a wide range of different branches of industry such as the life sciences chemicals petrochemicals oil and gas food and no less importantly in custody transfer applications. Considering the mass flow rate equation it appears that for a given area and a fixed density we could increase the mass flow rate indefinitely by simply increasing the velocity.
