Q. What is the main disadvantage of an orifice meter?

Answer

Both orifice and venturi meters establish a limitation in the flow channel. It is made up of a single chamber that was created for the purpose of accurate measuring the flow rate of a liquid or gas. Let’s identify the disadvantages of the orifice meter:Fluid homogeneity is required.Single-phase liquids are required.Axial velocity vectors must be in motion.The fluid pressure drops as a result.The fluid's density, pressure, and viscosity all impact its precision.Definition of the limitations of viscosity measurement.Maintaining precision calls for straight conduits.If liquid flow is to be accurately measured, a specialized pipe is required.Their ability for travel is limited.
