The flow nozzle is a type of orifice plate that is used to measure the flow rate of fluids. It is a relatively new type of orifice plate that is designed to provide improved accuracy and repeatability.
The flow nozzle is named after the International Society of Automation (ISA), which developed the standard for its design and installation. The ISA 1932 standard specifies the dimensions and tolerances of the flow nozzle, as well as the requirements for its installation.
The flow nozzle is characterized by its long, tapered inlet. This inlet helps to create a smooth flow of fluid past the orifice, which improves the accuracy of the measurement. The flow nozzle also has a smaller orifice diameter than a conventional orifice plate, which further improves the accuracy.
