Nozzle

Description

Design of the nozzle in accordance with the ISO5167, BS1042, ASME.MFC.3M or ISO TR15377 :2007 standards  No need of calibration – standardised principle  Accuracy, repeatability and reliability of the flow element  Use for non viscous fluids at high velocity  Especially suitable for high velocity measurement of vapor flow  Very long life-time product  Different types of flow nozzles : ISA1932, long radius, venturi-nozzle
