Hi Atanu - due to the unique design of vortex shedder bars, and the placement of the flappers behind, it is not possible to read flow in the reverse direction using a single Vortex meter. There are plenty of other technologies that can measure bidirectional flow such as Magnetic Flow Meters (for conductive liquids) or Coriolis Flow Meters (for liquids or gases). If you decide to pursue a bidirectional solution using two Vortex meters, ensure you have 40 diameters of pipe between them to dissipate the profile effects of the first shedder bar before encountering the second. Less diameters may be possible, but the results are completely process dependent and hence would require in-situ testing to determine feasibility and/or appropriate k-factor adjustments.
