Venturi Tubes

Product catalog summary
Overview of Venturi Tubes
Venturi tubes are used in flow measurement and offer significant advantages over other methods such as orifice plates and flow nozzles. They provide approximately 60% more capacity than orifice plates for the same differential pressure and orifice-to-pipe ratio. Additionally, they have a low permanent pressure loss, ranging from 10% to 20% of the differential pressure.
Advantages
  • Higher capacity compared to orifice plates.
  • Lower permanent pressure loss.
  • Less affected by variations in Reynolds number compared to flow nozzles and orifice plates.
Recommendations
Venturi tubes are recommended for applications where minimizing line pressure loss is crucial, and where long-lasting equipment with stable flow coefficients is desired.

PETROSYSTEM Srl Via Gaspare Spontini, 29/4 - 00043 Ciampino (Roma) – Italy Tel:+39 06 7932.1621 Fax:+39 06 7932.1160 Email: [email protected] Web: www.petrosystem.it I Tubi Di Venturi Nelle misure di portata i tubi Venturi, come i boccagli, offrono il vantaggio di avere circa il 60 % in più della capacità di un diaframma, a parità di differenziale e di rapporto di strozzamento, e una perdita permanente di solo il 10 / 20% del differenziale. Inotre sono meno influenzati che non i diaframmi ed i boccagli dalla variazione del numero di Reynolds. Il loro impiego pertanto è raccomandato quando si vuole avere una minima perdita di carico unitamente a una lunga durata e stabilità del coefficiente di efflusso. Venturi tubes are characterized by several outstanding features. They have the same capacity as flow nozzles, which is about 60 % greater than that of orifice plates for the same operating differential and orifice to pipe ratio. Permanent pressure loss is very low ranging from 10 to 20 % of the differential and Reynolds number variations have a much slighter effect on Venturi tubes than on flow nozzles or orificeplates. Their use is recommended in those applications where low line pressure loss is at premium and when long lasting equipment and stable flow coefficients are desired.
