摘要： A Coriolis effect mass flow meter having a brace bar of improved flexibility which reduces the stress concentration in a brace bar as well as in areas of meter's flow tubes proximate the brace bar and flow tubes of the flow meter. A brace bar means is disclosed that has a void in an area between its holes that receive the flow tubes. This void increases the flexibility of the brace bar and shifts the concentration of operational and manufacturing induced stresses away from the braze joints between the brace bar and the flow tubes. The stresses are reduced and shifted away from the flow tubes to an area within the brace bar that is less critical to the overall life and reliability of the flow tubes. Meter sensitivity is improved due to enhanced flexibility of the present invention's brace bar in response to the motion induced by the Coriolis effect. Additional embodiments are disclosed which also provide increased flexibility of the brace bar while maintaining required rigidity to resist undesirable independent motion of the flow tubes.

摘要： Apparatus is disclosed for a Coriolis mass flow rate meter and specifically such a meter that is suited for operation at relatively high temperatures, such as in excess of approximately 500.degree. F. (approximately 260.degree. C.) and preferbly as high as 800.degree. F. (approximately 427.degree. C.), and that does not utilize a cooling purge.

摘要： A Coriolis flowmeter having a pair of parallel vibrating flow tubes equipped with a driver and sensors each comprising a fixed non-movable coil and a pair of magnets affixed to the vibrating flow tubes. Each coil magnetically cooperates with a unique pair of magnets. In a first embodiment, the coil is affixed to a non-movable member of the flowmeter. In another embodiment, the non-movable coil is affixed only to a spring sub-assembly which is affixed to the flow tubes which vibrate out-of-phase with respect to each other.

摘要： A viscometer for improved sanitary measurement of the viscosity of industrial fluids. The present invention provides a viscometer integral with a flow meter or a viscometer than can be mounted onto an existing flow meter. The viscometer includes two adjacent parallel flow channels having relatively flat inner surfaces. A differential pressure element is mounted between the adjacent flow channels to sense the differential pressure between the fluid flow of the two channels. The differential pressure is input along with the mass flow rate and fluid density to calculate the fluid viscosity.
