Made by experienced code qualified welders, Daniel meter tubes are accurate and dependable instruments that adhere to the highest quality standards. 

A meter tube consist of an orifice fitting (Daniel Senior, Junior, Simplex or Orifice Flange Union), a length of pipe upstream of the fitting and a corresponding length of pipe downstream of the fitting. There is also, in most cases, a flow conditioner (Daniel flow conditioning plate or 19 tube concentric bundle) upstream of the orifice as well.

The meter tube “smooths out” turbulence, often a condition that interferes with accurate measurement of flowing media, ensuring consistent measurement accuracy.

With Daniel’s dedicated approach to quality, extra steps are taken during every phase of meter tubes' design and production.  

Quality fabrication
Close quality control guarantees highly accurate fabrication of Meter Tubes for Orifice Meters. Special jigs and fixtures are used to assure precise alignment of tube and fitting so there are no steps or offsets. All welds are ground and micrometer readings are made.

Testing
Radiography and hydrostatic testing is available for Daniel Orifice Meters to ensure measurement accuracy. Micrometer and internal surface roughness readings are recorded and supplied with each meter tube.

Paint and coating
A special quick-drying paint is applied as standard on Meter Tubes. Sand-blasting and corrosion-resistant coatings are also available.
