A method and apparatus for measuring the flow rate of bitumen froth through a pipeline is provided. A flow meter device is provided including a conduit comprising an approach section having a diameter less than the diameter of the pipeline and a venturi section having in series a converging section, a throat section and, optionally, a diverging section, the converging section of the venturi section being disposed relative to the approach section, and a means for measuring the pressure difference AP between two points that are separate from one another in the flow direction, one point being on the approach section and the other point being on the throat section. In one embodiment, a heating means for heating the conduit is provided.
La présente invention concerne un appareil et méthode de mesure du débit de mousse de bitume traversant un pipeline. Un débitmètre est fourni, qui comprend un conduit comportant une section d'approche avec un diamètre inférieur à celui du pipeline, et une section de venturi muni d'une série de sections convergentes, une section d'étranglement et, en option, une section de divergence, la section de convergence du venturi étant disposée à proximité de la section d'approche, et un dispositif pour mesure la pression différentielle AP entre deux points, séparés l'un de l'autre dans la section d'écoulement, un point se trouvant sur la section d'approche et l'autre se trouvant au point d'étranglement. Une version de l'invention prévoit un dispositif de chauffage du conduit.
