摘要
A vortex flow meter includes a vortex responsive assembly having a diaphragm. The diaphragm seals a base end of the assembly to form an isolation chamber. The assembly is adapted to seal an opening in a sidewall of a flow passage. Support struts preferably protrude from the assembly into the flow passage. In one configuration, a vortex oscillation sensor plate has a proximate edge supported on the diaphragm and an opposite distal edge that is unsupported. The vortex oscillation sensor plate has upstream and downstream edges preferably supported by the support struts. A pivoting strut extends along a central region of the vortex oscillation sensor plate. The pivoting strut extends through the diaphragm. The pivoting strut transfers vortex oscillations to a sensor. An electronic transmitter circuit receives a sensor output and provides an output related to flow of the fluid.
