Daniel Venturi Tubes

Daniel

Corrosion-resistant and virtually maintenance free, Daniel™ Venturi Tubes are an ideal flow measurement solution for non-viscous fluids that contain hydrocarbons and other potentially corrosive elements, including LNG. This low-pressure metering device provides constant accuracy, greater capacity, high-pressure recovery and minimal permanent pressure loss and is available in a variety of ANSI ratings to ensure reliable, sustained performance for a variety of applications. Venturi tubes can be installed horizontally, vertically or any angle in between and have shorter upstream piping requirements to simplify installation and reduce costs.
