Flow rate vs volumetric flow rate

WebVolumetric flow meters are types of flow meters that operate linearly with respect to the volume flow rate – they make a flow measurement of the amount of either a liquid or a gas flowing through a pipe by measuring the velocity at which it is flowing. Volumetric flow meters measure volumetric flow rate, differing from mass flow meters, like Coriolis … WebOct 31, 2024 · The volume flow rate at the orifice plate can then be expressed as: Where: A 2 = flow cross-section area at the orifice plate (m 2) Pressure loss due to orifice plate. In reality, there is always some pressure loss due to frictional effects when fluid passes through orifice plates. As a result, the fluid flow velocity (and flow rate) at the ...
