Venturi tubes offer features that set them apart from other primary flow elements. A WIKA Venturi tube is made from bar stock or welded sheet. Compared to other differential pressure flow meters, a Venturi tube offers higher pressure recovery and is used when upstream and downstream pipe requirements are low. Due to their reliability, ease of handling and high pressure recovery, Venturi tubes are often used in systems with a low pressure gradient. Since a large proportion of the output pressure is maintained, the cost of pumping is kept to a minimum.
