“…Vortex precession flowmeter is based on the vortex precession phenomenon, it possesses many advantages such as low corrosion, high reliability, easy to install and a short straight pipe required. It is suitable for measuring gas like petroleum, steam and natural gas [4][5][6]. But in the application, the vortex precession flowmeter has problems of large pressure loss and excessive energy consumption during large flow process, so the use of swirl flowmeter is limited [7].…”

This paper mainly introduces the technical parameters and the structure of low pressure loss and wide range swirlmeter. We redesigned the vortex generator of swirlmeter and changed the traditional spiral blade to linear blade. The included angle between the blade and the axis was reduced from 60 degrees to 30 degrees, which can increase the flow area and reduce the pressure loss. We converted the blade from stainless steel to the shape of isometric changed curve, and the frequency detection sensor is designed to four piezoelectric crystal sheet, the pressure loss is lower than that of spiral vortex generator. The test results show that the pressure loss of improved swirlmeter is decreased and the lower limit of measurement is reduced.

“…As in previous studies on the swirlmeter, experimental tests are the main method of analysis. 3 Dijstelbergen 4 elaborated on its operating principle and conducted experimental tests on the swirlmeter. The results obtained were that the output of the meter was linear and independent of viscosity and density.…”

The performance of a swirlmeter (or vortex precession flowmeter) was numerically and experimentally evaluated. With methods from computational fluid dynamics, the flow fields of the swirlmeter were analyzed, revealing their flow characteristics. To obtain detailed flow information with the Re-Normalization Group k – ε turbulence model and SIMPLE arithmetic, which couples pressure and velocity, the three-dimensional unsteady incompressible flow of a swirlmeter was numerically simulated. By varying the cone angle of the swirler, the performance of the swirlmeter was analyzed. The results show that the pressure fluctuation frequency inside has a linear response to flow rate, and the swirlmeter achieves high accuracy over a large measurement range. The pressure fluctuation near the region between throat and diffusor was stronger than other regions offering then an ideal location to mount the piezoelectric sensors. Different swirler cone angles were shown to influence both pressure drop and fluctuation; smaller cone angles produced higher frequency fluctuations but larger pressure loss.
