ABSTRACT:
An external sensing system for a vortex-type flowmeter in which the fluid to be metered is conducted through a flow tube having an obstacle assembly therein to produce periodic vortices which cause a deflectable section of the assembly to vibrate at the same rate. These vibrations are mechanically transmitted to a point outside the flow tube which is linked to the diaphragm of a pneumatic cell to generate in the cell chamber a compressional wave that is conveyed by a pipe to the cavity of a pick-up cell having a force sensor therein. The pipe has a constricted passage which acts to attenuate the compressional wave and thereby reduce the dynamic range of the system, the pipe also serving to effectively isolate the sensor from the temperature of the fluid being metered. The sensor yields a signal whose amplitude is indicative of the mass of the fluid and whose frequency is indicative of the volumetric flow rate thereof.
