Abstract
A flowmeter of the vortex type in which an obstacle assembly mounted in a flow tube of relatively small diameter causes vortices to be shed at a frequency which is a function of flow rate. The assembly includes a block fixedly mounted across the flow tube at right angles to the direction of flow, the block having a substantially square cross-section to present a flat face to the incoming fluid. The upper and lower rear corners of the block are bevelled to define a flat rear face of reduced area, the resultant block configuration acting to enhance the shedding characteristics of the assembly and to produce substantially linear flow rate measurements at low Reynolds numbers.
