Flow Measurement
QBar™
Averaging pitot tube for accurate, stable flow measurement with low pressure loss.
Overview
Low pressure loss, economical to install.
The QBar™ is an averaging pitot tube with a relatively small aspect ratio, so it incurs very low pressure loss and is economical to purchase and install, especially in larger pipelines and rectangular ducts.
Retractable QBar™ versions allow insertion and withdrawal from a pipeline without draining the process fluid.
QBar™ sensor design features deliver accurate and stable measurement over a very wide flow range. Compared with other DP devices, the QBar™ creates much less pressure loss, keeping the energy cost of restoring lost pressure to a minimum. Installation is also straightforward, typically requiring only a single hole in the pipe wall.
