Daniel Ultrasonic Meter Tubes
Daniel™ Ultrasonic Meter Tubes significantly minimize the adverse effects of turbulence on flow measurement accuracy by expertly integrating a Daniel Ultrasonic Meter and a flow conditioner or tube bundle with upstream and downstream pipe lengths per end user requirements.
Built by code-qualified welders, Daniel meter tubes adhere to the highest quality standards to ensure internal roundness, a smooth, even surface finish, and precise alignment with no steps or offsets for superior, long-term measurement performance. Pre-assembly at the factory allows for rapid installation and startup to save time and reduce costs.

  • Improve long-term accuracy with fabricated solution offering superior internal roundness and a smooth, even surface
  • Significantly minimize the effects of turbulence with precise alignment that eliminates steps or offsets
  • Simplify startup and improve long-term use with one .5-in and one .75-in branch connection on the downstream tube
  • Meet application and/or installation needs with weld fitting and ends that can be beveled, flanged or reduced
  • Ensure performance in accordance with ASME with optional hydrostatic testing to 1.5 times operating pressure
  • Verify and allow for field compensation using factory supplied micrometer and internal surface roughness readings
  • Save time and money on installation and startup with fully-assembled solution
  • Improve durability and extend product life with optional sand-blasted and corrosion-resistant coatings
