Flow Nozzles

For Topside Measurement

ISA 1932 and ASME Flow Nozzles are accurate devices for measuring the flow of high velocity, non-viscous fluids e.g. Steam and other high velocity gases. Flow Nozzles are particularly suitable for erosive fluids where the sharp edge of an orifice plate could quickly deteriorate.

Solartron ISA offer a range of Flow Nozzle designs including flanged, buttweld and insert types. All Flow Nozzle types are designed in accordance with ISO 5167 to suit various pipe-work configurations, overall length requirements, orientations and end connections. Lines sizes available range from 50mm up to 1000mm.

Flow Nozzle design can provide a key cost saving benefit, as the profile is virtually immune to any wear or erosion. Flow Nozzles are often regarded as “fit and forget” devices with very little maintenance and inspection required.

Solartron ISA offers Flow Nozzle designs to suit the needs of any pipe-work configuration, with different lengths, orientations and end connections available. We provide complete Engineering support from initial design and sizing concepts to manufactured final products.
