Vortex Meter Velocity Ranges:
The Vortex meter has different minimum and maximum flow velocities it can measure based on the fluid type and meter size. Please note the values below for proper sizing of your meter.
1/2” ANSI Flange: 4-7 0m/s.
1” ANSI Flange: 3-70m/s.
2” to 12” ANSI Flange: 1.5-70m/s.
1/2” ANSI Flange: 4-65m/s.
1” ANSI Flange: 3-65m/s.
2” to 12” ANSI Flange: 1.5~65m/s.
1/2” to 12” ANSI Flange: 0.2-10m/s.
Nominal Vortex Flow Rates for Air
The table below gives the minimum, nominal, and maximum velocities for the Vortex Meter for gases to assist users familiar with Thermal Mass Flow Meter sizing guides relative to air, with a density of 0.075 lb/ft^3 for reference. As the pressure goes up the flows go up as well. For example, if the pressure is DOUBLED, so too does the mass flow. Download chart below here:
IMPORTANT Note to Thermal Mass Flow Meter users...
Did you know that Multivariable Vortex Flow Meters offer a significant advantage over Thermal Mass Flow Meters when it is not necessary to measure ultra low or ultra high flows?
Did you know that a Multivariable Vortex Meter is not affected bygas composition? This means you can change gas composition and STILL report the proper Mass Flow! Why utilize a Gas Chromatograph to determine gas composition to correct your Thermal Mass Flow Meter measurement? If you need ultra low flows it makes sense but if your minimum flows are within the measuring range of a Vortex meter then consider a Multivariable Vortex Mass Flow Meter.
Ever have problems with temperature swings causing your Thermal Mass Flow meter to over or under report the flow measurement? The Multivariable Vortex Mass Flow Meter does not exhibit these symptoms simply because the vortex shedding velocity is not a function of temperature or pressure. And, with the Multivariable Vortex Meters built in Pressure and Temperature sensors you can get true Mass Flow, Pressure, AND Temperature and even gather Volume flow on those rare occasions when deemed necessary. And, you have a true pressure measurement as well as the Mass Flow and temperature. All at a price very competitive with Thermal Mass Flow Meters.
HOWEVER, if you DO need very low or very high flows we suggest the use of Thermal Mass Flow Meters and suggest you consider the use of the Sage Metering Prime for the most cost effective solution. Tell them we sent you! Visit Sage Metering if you need to measure very low flows, or need an Insertion Thermal Mass Flow Meter. Refer to the chart above for the minimum and maximum flows.
