Intelligent low-power-consumption vortex precession flowmeter

Abstract

The invention discloses an intelligent low-power-consumption vortex precession flowmeter. The intelligent low-power-consumption vortex precession flowmeter comprises a shell, a vortex generator, a flow totalizer, a flow sensor and a pressure sensor, wherein a medium inlet channel, a middle channel and a medium outlet channel are respectively formed in the shell; the vortex generator comprises a generator body and a plurality of flow guiding blades which are arranged spirally; the flow guiding blades and the generator body are integrally machined and formed; the radial size of the generator body is gradually reduced from one end, which is close to a port of the medium inlet channel, to the other end; and the radial sizes of the flow guiding blades are gradually reduced from the large-radial-size end of the generator body to the small-radial-size end of the generator body. The structure of the vortex generator is modified, the vortex strength can be improved, the power consumption is low, meanwhile, obstruction to the medium which flows through the flowmeter is greatly reduced, pressure loss is reduced, and the measurement precision is improved favorably.

Description

technical field [0001] The invention relates to the field of flowmeters, in particular to an intelligent low-power-consumption swirl precession vortex flowmeter. Background technique [0002] Measurement is the eye of industrial production, and flow measurement is one of the components of measurement science and technology. It is closely related to national economy, national defense construction and scientific research.
