CORIOLIS MASSENDURCHFLUSSMESSER MIT EINSTELLBARER DRUCK UND DICHTEEMPFINDLICHKEIT |
摘要 |
A flow meter apparatus for measuring attributes of a fluid using the Coriolis principle is disclosed. The apparatus comprises: (A) a body (1) capable of being inserted into and surrounded by the fluid, (B) an actuator (5,6), disposed within the body (1), for vibrating a surface of the body in a radial mode of vibration, the vibrating surface developing Coriolis forces within the fluid (28), (C) a detector (9,10), coupled to the surface, for measuring motion of the surface, the motion being a function of Coriolis forces developed in the fluid and (D) a circuit, coupled to the measuring detector, for determining an attribute of the fluid as a function of the motion of the surface. In a preferred embodiment of the invention, a conduit surrounds the apparatus and is coupled to the detector. The apparatus allows precise detection of mass flow rate, pressure, density and viscosity of the fluid surrounding the apparatus. <IMAGE> |
