VOLUME FLOW MEASURING ELEMENT - SONIC NOZZLE

A class with identifier http://staging4.data.posccaesar.org/iso/15926-4/rdl/RDS2221837

MetadataThis section provides information about 'RDS2221837'.

DefinitionA <VOLUME FLOW MEASURING ELEMENT - SONIC NOZZLE> is an <INSTRUMENTATION ITEM> and a <VOLUME FLOW MEASURING ELEMENT> that is operated by pressurizing the inlet of the venturi or evacuating the outlet in order to achieve an inlet-to-outlet pressure ratio of 1.4 to 1 or greater. This ratio maintains the nozzle in a choked or sonic state. In this state, only the upstream pressure and temperature influence the flow rate of gas through the nozzle. The flow rate through the nozzle becomes nearly a linear function of the inlet pressure which increases the thereby doubling the flow rate of gas
