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.As well, it is important to note that Thermal Mass Flow Meters are quite sensitive to moisture in the flow stream. The most common undesirable effect is momentary flow spikes that can upset your control system. Vortex Meters, on the other hand are NOT sensitive to moisture in the flow stream and offer a significant advantage over Thermal Mass Flow Meters if such spikes are determined to be undesirable.Have you 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. As well, Thermal Mass Flow Meters are ideal as "Insertion Meters" as they are small and if, and ONLY if, there is no moisture, or gas composition changes then the Thermal Mass Flow Meter is a very good choice. Otherwise, the Vortex is the best choice as it has NO sensitivity to the gas composition or droplets or hydrocarbon particulate.Refer to the chart above for the minimum and maximum flows for the Vortex Mass Flow Meter. Refer to the minimum and maximum velocities for the fluid you wish to use to see if a vortex meter is a good choice. If your flow is within the velocity range of the Vortex meter AND you have moisture or any change in gas composition then a Vortex meter is a better choice over the Thermal Mass Flow Meter. Important Note: Vortex Flow Meters want to be rigidly mounted or isolated from vibration to prevent the vibrating energy to be transmitted to the Vortex Piezo Sensors. This can be accomplished by rigid mounts to a solid base or good vibration isolation.How to use button interface and ModBus RTU video:To get the most out of the video open the link below and print out the document or open it in another window.

Flow meters for liquids. Accuracy of ± 0.5%$2,112.00 – $10,450.00
Electromagnetic flow meters, also called mag meters or magnetic meters, are volumetric flow meters which do not have any moving parts to wear, reducing the need for maintenance or replacement. Accuracy over a wide flow range can be as good as ± 0.5% of flow rate or better.
Insertion Magmeter for liquids and slurries. Accuracy of ± 0.5%$2,988.00
The ISM 5.0 Insertion Magmeter operates based on Faraday's Law of electromagnetic induction: as flow velocity of a liquid increases through the magnetic field generated by the sensor head of the ISM flow meter, electrodes measure the voltage increase to calculate flow. ... The voltage readings are sampled & averaged.
