Flobar Insertion Pitot Tube
An alternative differential pressure flow measurement system uses a Pitot tube. RM&C have developed this technique with the Flobar averaging Pitot Tube.
The flobar tubes contain no moving parts, standard models are manufactured from stainless steel, though alternative material requirements are readily accomodated.
The flobar is available for most line sizes, even above 3 meters in diameter and with suitable flanged or screwed fittings. For smaller line sizes, complete pipe sections are produced with welded-in Pitot probes.
Various styles of mechanical or electronic displays can be used to convert the derived DP measurement into a line flow reading, these are listed under the available accessories for these products.
