Embodiment Construction

[0019] Referring now to the drawings, first to the attached figure 1 , one embodiment of a vortex flowmeter for measuring fluid velocity, generally designated 101. The vortex flowmeter 101 includes a flow conduit 103 through which fluid flows. Flow conduit 103 is suitably configured to fit within a fluid flow line (not shown). For example, process connections 105 (eg, flanges) are located on opposite ends of the flow conduit 103 for connecting the inlet 107 and outlet 109 of the flow conduit to the respective conduit ends of the pipeline. It is also common in the industry to use so-called wafer connections, so that the flowmeter is installed in the fluid line, and the flow line is adapted to the wafer connection (or any other type of connection, if desired). pieces).

[0020] A bluff body 121 (sometimes referred to in the industry as a swirl remover or strip) is located in the flow conduit 103 . The bluff body 121 is a structure that partially blocks the flow of fluid thro...

Abstract

A configuration tool for a vortex flowmeter, the vortex flowmeter includes a flow pipe; a bluff body placed in the flow pipe for removing the vortex in the fluid; and a pressure sensor configured to obtain a fluid pressure indicative of a change over time signal with vortex-related oscillations. The configuration tool includes a processor that determines the type of fluid flowing through the flow conduit based on the magnitude of the oscillation. The processor sets a fluid type setting of the vortex flow meter to match a predetermined type of fluid. An alarm system for a control system including the vortex flowmeter includes a processor that estimates a density of fluid flowing through the flow conduit based on the magnitude and compares the estimated fluid density to a fluid density configuration setting. The processor activates an alarm when the difference between the estimated density and the fluid density configuration setting exceeds a threshold.

Description

technical field [0001] The present invention generally relates to a vortex flow meter. Background technique [0002] Flow meters measure the flow rate of fluids in pipes or other paths. A fluid may be, for example, a gas or a liquid, and be compressible or incompressible. One type of flowmeter is a vortex flowmeter, and the parameters measured by it include, for example, the flow rate based on the principle of vortex removal. Swirl shedding refers to a natural process of flow through a bluff body (sometimes referred to as an inverted body) causing a boundary layer of slow moving fluid to form along the surface of the bluff body. A region of low pressure is created behind the bluff body and causes the boundary layer to roll up, creating a continuous vortex on the opposite side of the bluff body. The frequency of the vortex is related to the flow rate. Therefore, flow velocity can be measured by detecting eddies. For example, vortices are related to pressure changes in th...
