The VTC classical Venturi tube is designed for line sizes from 25 to 1200 mm (1 to 48 in.) and measures clean liquids and gases with low pressure loss, typically 5 to 12% of the differential head. It is manufactured from carbon steel or stainless steel, with flanges and tappings conforming to standard pressure ratings and NPT or BSPT configurations. The device complies with ISO 5167-1:2003, ASME VIII, and PED 97/23/EC, and is supported by full NDT documentation including hydrostatic testing, radiography, and material certificates to BS EN 10204 3.1B/C.
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.
