ABSTRACT:
A flowmeter of the vortex type in which an obstacle assembly mounted in a flow tube causes vortices to be shed at a frequency that 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 predetermined geometry whose cross-section is uniform throughout its length. Fitting over the front face of the block is a replaceable adapter cap having a channel therein which conforms to the profile of the block and acts as a socket therefor. The formation of the adapter cap is such as to effectively expand the cross-section of the block without altering the geometric configuration thereof whereby the resultant expanded block restricts the effective area in the flow tube of fluid passing by the block, thereby making it possible to measure flow rates below the normal operating range of the meter.
