A differential pressure device installed in a side pocket tool (146) for use in a borehole where a differential pressure (P1, P2) is converted into a linear motion by a main bellows (62) and this main bellows is connected by a linear to rotative force device or torque converter (86) to develop a torque force about the torque axis (44). A second bellows (80) is used as an interior, control bellows for limiting the differential pressure applied to the exterior of main bellows (62) so that overpressure will not destroy either bellows. The torque force is applied to a torque responsive pressure device (146) to develop a pressure signal. The tool is preferably used in a side pocket mandrel (140), and the pressure signal measurements that allow determination of flow rate by standard hydraulic equations can be recorded downhole by a memory recorder (144) or else transmitted to the earth's surface for real time recording.

Dispositif de pression différentielle monté dans un outil de poche latérale (146) conçu pour être utilisé dans un trou de sondage dans lequel une pression différentielle (P1, P2) est convertie en déplacement linéaire par un soufflet principal (62) accouplé à un dispositif de conversion de force linéaire en force rotative ou convertisseur de couple (86), afin de créer une force de torsion autour de l'axe de torsion (44). Un deuxième soufflet (80) est utilisé en tant que soufflet intérieur de commande servant à limiter la pression différentielle appliquée à l'extérieur du soufflet principal (62), de sorte que la surpression ne détruira aucun des deux soufflets. La force de torsion est appliquée à un dispositif de pression (146) sensible au couple de torsion, afin de produire un signal de pression. Cet outil est, de préférence, utilisé dans un mandrin de poche latérale (140) et les mesures des signaux de pression permettant de déterminer un débit au moyen d'équations hydrauliques classiques, peuvent être enregistrées au fond du puits par un enregistreur à mémoire (144) ou bien transmises à la surface terrestre afin d'être enregistrées en temps réel.
