Abstract
A flow meter comprises a divergent nozzle region 6 and a plug 10 which is axially displaceable within the nozzle region 6 under the influence of a flowing fluid. The plug 10 is guided, during displacement, by vanes 38 extending inwardly from the wall of the nozzle region 6. The plug 10 is displaceable against the action of a spring 20 which abuts a support ring 22. The force applied by the spring 20 to the support ring 22 is transmitted to a strain element 26. Processing circuitry 36 receives inputs from strain gauges 32 and provides an output representing the flow rate of fluid through the flow meter.
