ABSTRACT:
A flow meter apparatus for measuring attributes of a fluid using the Coriolis principle is disclosed. The apparatus comprises (1) a body capable of being inserted into and surrounded by the fluid, (2) an actuator, disposed within the body, for vibrating a surface of the body in a radial mode of vibration, the vibrating surface developing Coriolis forces within the fluid, (3) a detector, coupled to the surface, for measuring motion of the surface, the motion being a function of Coriolis forces developed in the fluid and (4) 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.
