ASME Flow Nozzle
The AFM-N flow nozzle is an ASME full performance, high accuracy and reliability differential producing flow measurement device.
Orifice Plate Meter Run
The AFM-ORPMR is designed for measurement of gas or liquids in pressurized piping. The “orifice meter tube” as defined by the ISO 5167, ASME MFC and American Gas Association Report Number 3 specifications.
Low Beta Ratio and High Beta Ratio
The flow nozzle is recommended for steam flow and other high-velocity fluids, wet gases, and both clean and dirty liquids
Required upstream pipe length is 10 to 30 diameters
The rangeability is 4 to 1
Typical accuracy is 1-2% of full range
The viscosity effect is high
The relative pressure loss is medium
The relative is medium
Available in various carbon and stainless steels as well as Nickel, Monel, Inconel and Hastelloy. Custom materials and/or special coatings are also available. Within the Amity Computation Module, we are able to engineer flow nozzles to the specific requirements of our clients while optimizing for accuracy, resistance to wear and minimal pressure loss. Our control from engineering through production assures the engineering specifications are realized in the calibration and performance of the final product.
