Vortex Flow Meter RVL Series VRX-DS-01586-EN-08 April 2019 Product Data Sheet DESCRIPTION The RVL liquid flow meter uses vortex-shedding technology with embedded piezoelectric pressure sensors.

D v f St St known as the Strouhal number is a dimensionless number which has a decisive impact on the quality of vortex flow measurement. St the Strouhal-Number is a dimensionless number which defines the quality of the vortex flowrate measurements. Therefore the frequency of vortex shedding is proportional to the volume flow.

Hi F Maximum value of the flow measured in the process Lo T Minimum value of the temperature measured in the process Hi T Maximum value of the temperature measured in the process 832 Explanation display function DIS diS L Standard layout of the displayL1. - 20 to 350 deg C. When moving the vortex ﬂ owmeter always use a trolley and have at least two people carry it.

When the vortex ﬂ owmeter is processing. The meter has no moving parts and any potential for fluid contamination is eliminated by the non-metallic corrosion-resistant body materials. Be careful that no damage is caused to personnel through accidentally dropping it or by exerting excessive force on the vortex ﬂ owmeter.

Gas Liquid Steam Meter size. 11 Product Description VFM-250 series Vortex flow meters are designed for measuring the volumemass flow of liquids gases and steam based on Karman vortex principle.

Representative to obtain a computer sizing program that describes in greater detail the flow range for an application. The vortex ﬂ owmeter is a heavy instrument. Rosemount 8800 Weld-end vortex flow meter Flange gaskets are eliminated by welding the flow meter directly into your process piping The only vortex flow meter available with zero potential leak points Ideal for applications where reducing potential leak points is important Available with ½ inch through 12 inch 15 mm through 300 mm line sizes.

The flow causes these vortices to shed forming a vortex street Karman Vortex Street Fig. - 20 to 70 deg C. The meters come pre-calibrated for the specific range as determined by size.

The meter requires a nominal 24 VDC power source and outputs a visual display of flow as well as 4-20 mA proportional to flow and a field settable solid state relay for low flow alarm conditions. The Frequency f of vortex shedding is proportional to the flow velocity v and indirectly proportional to the width of the shedder d. Liquid 12 62 to 200 - 2000 m3h GasSteam 5 25 to 1380 - 11000 m3h Ambient Temperature.

The vortex frequency is proportional to the flow velocity in a specific range of Reynolds numbers. For best results calibrate the meter at least 1 time per year. Because the previous results indicated that small distances between generators with the common flow down are favorable for heat.

Figure 7 shows the streamwise development of an array of counter-rotating longitudinal vortices generated by a half-delta wing with H15 mm and α15. The two configurations described in the previous paragraph appear alternately in this array. The Karman vortices are detected by two piezoelectric elements installed in the upper part of the shedder bar.

1 and the accuracy is better than 5 of full scale. May 19 2015 Scientific Industries SI-0256C Vortex-Genie 2 Mixer with. The turndown is 10.

Measurement principle When a shedder bar is placed in a flow Karman vortices are generated on the downstream side of the bar.
