Overview

Venturi tubes are available for line sizes from 50 mm to 1200 mm (2 to 48in) and can measure a wide range of relatively clean liquids and gases. The units are designed to ISO5167-1:2003 and have a substantial overall length, being typically 5D long (D = nominal pipe size).

There are two variants, based on differing manufacturing methods: VSD and VFB

Data

  • VSD
    – machined from solid for pipe sizes DN50 to 250 (2 to 10 in)
  • VFB
    – fabricated from rolled plate for pipe sizes DN200 to 1200 (8 to 48 in)
