Orifice plate flowmeter performance under pulsating flow conditions

Current need for cost and energy savings increases the demand for accurate measurement of mass flow rate. Measuring flow rate through a pipe is an important process in many industries, such as natural gas transport, feeding systems in petrochemicals, automotive and hydraulic applications. Pressure...
