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

AI Technical Summary

Problems solved by technology

[0003] The existing precession vortex flowmeter usually includes a housing, a vortex generator, a flow totalizer, a flow sensor and a pressure sensor. The inside of the housing is respectively formed with a medium inlet, an intermediate channel and a medium outlet, and the vortex generator is installed in the medium inlet. , the flow totalizer is installed on the upper end of the shell, and the flow sensor and pressure sensor are set in the shell and connected to the flow totalizer. Large, when the medium flows through the vortex generator, the resistance to the flowing medium is relatively large, resulting in a large loss of medium pressure. At the same time, the vortex strength is limited and the power consumption is high, which will eventually affect the measurement accuracy of the entire flowmeter.
