Flow Measurement
QBar™ Averaging Pitot Tube
Accuracy and stability, proven across the industry spectrum.
Overview
Low pressure loss, economical to install.
Being insertion devices with a relatively small aspect ratio, Pitot Tubes incur a very low pressure loss and are also very economical both to purchase and install, especially in larger pipelines and rectangular ducts.
Pitot Tubes are also available in retractable versions, allowing insertion and withdrawal from a pipeline without draining the process fluid.
Pitot Tubes have unique sensor design features, offering more accurate and more stable measurement over a very wide flow range. Pitot Tubes create a pressure loss many times lower than that of other DP devices, meaning that energy costs incurred in restoring the lost pressure are minimal. Installation is also much simpler as it typically only requires a single hole in the pipe wall.
