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.

Features

  • Accurately measure a variety of fluids, including LNG, water, vapor, steam, gas, chemicals, slurries and sludge
  • Achieve lower permanent pressure loss (~5 to 15% of differential pressure) and greater capacity vs. other devices
  • Realize superior performance in highly corrosive environments with low susceptibility to erosion
  • Ensure reliable, sustained performance by selecting from a wide variety of materials and coatings
  • Simplify installation and reduce costs with short upstream piping requirement
  • Increase design flexibility with ability to install vertically, horizontally or at an angle
  • Virtually eliminate maintenance time and costs with no moving parts and simple configuration
  • Rely on manufacturing in strict accordance with ASME MFC-3M and ISO 5167 specifications
