ST – Flow Nozzles

Flow Nozzles

Flow Nozzles are reliable, easy to use and maintenance-free flow meters. They are particularly well suited to the measurement of high velocity and abrasive process in gas, steam and liquid flows. Used in multiple industries with a wide variety of design options in accordance to ISO 5167-3 and ASME MFC3.

Features

  • Sur-Tech Flow Nozzles are available from 2″ to 50″ line sizes weld x weld or any flanged arrangement. There are typically 3 types of Flow Nozzle;

ISA 1932 Nozzles

  • Suitable for beta ranges from 0.3 to 0.8
  • Flanged, welded and insert type
  • Pressure tapping points are outside of the nozzle footprint

Venturi Nozzles

  • Design is a ISA 1932 nozzle with a diffuser
  • Low ratio nozzle with beta ranges from 0.2 to < 0.5
  • Flanged, welded and insert type
  • Pressure tapping points are outside of the nozzle footprint

Long Radius Nozzles

  • High ratio nozzle with beta ranges from 0.25 to < 0.8
  • Low ratio nozzle with beta ranges from 0.2 to < 0.5
  • Flanged, welded and insert type
  • Pressure tapping points are outside of the nozzle footprint
