1” ANSI Flange: 3-70m/s or 590- 13,800 f/m or 9.8-230 f/s

2” to 12” ANSI Flange: 1.5-70m/s or 30.2-13,800 f/m or 4.92-230 f/s

Gas:

1/2” ANSI Flange: 4-65m/s or 787-12,790 f/m or 13- 213 f/s

1” ANSI Flange: 3-65m/s or 590-12, 790 f/m or 9.8- 213 f/s

2” to 12” ANSI Flange: 1.5-65m/s or 300- 12,790 f/m or 4.9-213 f/s

Liquid:

1/2” to 12” ANSI Flange: 0.2-10m/s or 40- 1,968 f/m or .66-32.8 f/s

Nominal Vortex Flow Rates for Air

Provided in the table below are the minimum, nominal, and maximum velocities applicable to the Vortex Meter for gases. This information serves as a helpful guide for those familiar with Thermal Mass Flow Meter sizing guides concerning air, with a reference density of 0.075 lb/ft^3. As pressure increases, flow rates correspondingly increase as well. For instance, if the pressure doubles, the mass flow will also double. Download chart below here:

IMPORTANT NOTE TO THERMAL MASS FLOW METER USERS...

Are you aware of the advantages that Multivariable Vortex Flow Meters have over Thermal Mass Flow Meters in certain flow measurement scenarios? Specifically, when the need to measure ultra low or ultra high flows is not present, Multivariable Vortex Flow Meters can provide significant benefits. Are you aware that Multivariable Vortex Meters have the unique advantage of being unaffected by changes in gas composition? This means that even if the gas composition is altered, the Mass Flow can still be accurately reported. Why rely on Gas Chromatographs to determine gas composition and correct Thermal Mass Flow Meter measurements when a Multivariable Vortex Mass Flow Meter can achieve the same results without the added complexity and cost? While Gas Chromatographs may be necessary for ultra-low flows, if your minimum flows fall within the measuring range of a Vortex meter, it's worth considering using a Multivariable Vortex Mass Flow Meter. It's worth highlighting that when using Thermal Mass Flow Meters, it's crucial to consider the presence of moisture in the flow stream since they are highly sensitive to it. These devices can cause temporary flow spikes, which may disrupt your control system. However, Vortex Meters do not suffer from this issue, as they are not affected by moisture in the flow stream. If you want to avoid these momentary flow spikes, Vortex Meters offer a considerable advantage over Thermal Mass Flow Meters. Are you tired of facing issues with temperature variations leading to inaccurate readings from your Thermal Mass Flow meter? Look no further than the Multivariable Vortex Mass Flow Meter, which eliminates this problem by relying on vortex shedding velocity that remains unaffected by temperature and pressure changes. Moreover, the Multivariable Vortex Meter comes equipped with built-in Pressure and Temperature sensors, enabling you to measure Mass Flow, Pressure, Temperature, and even Volume flow if required. You'll also obtain an accurate pressure measurement alongside Mass Flow and temperature readings - all at a price that competes favorably with Thermal Mass Flow Meters. In situations where extremely low or high flows are required, we highly recommend utilizing Thermal Mass Flow Meters. These instruments are also well-suited for use as "Insertion Meters" due to their compact size. However, it's essential to note that Thermal Mass Flow Meters should only be used if there is no presence of moisture or gas composition changes. On the other hand, if your application involves any droplets or hydrocarbon particulate, Vortex flow meters are the ideal choice as they are not sensitive to gas composition or contaminants. Please consult the provided chart for the minimum and maximum flow rates applicable to the Vortex Mass Flow Meter. To determine the suitability of a vortex meter, refer to the minimum and maximum velocities for the fluid you intend to measure. If your flow rate falls within the range of velocities supported by the Vortex meter and if your fluid contains moisture or has varying gas composition, then the Vortex meter is the ideal choice, surpassing even the Thermal Mass Flow Meter. Attention: To ensure accurate readings from Vortex Flow Meters, it is essential to mount them firmly or protect them from any vibrations that could interfere with the Vortex Piezo Sensors. This can be achieved by either using sturdy mounts attached to a stable base or employing effective vibration isolation techniques.

HOW TO INVOKE VARIABLE K-FACTORS IN THE TACTICAL FLOW METER VORTEX FLOW METER:

Please be advised that Screen 33 is intended for advanced users ONLY. DO NOT access this screen on your meter unless it is absolutely necessary. Before making any changes, it is crucial that you take note of all current settings. Additionally, please note that pressing the left button labeled HOLD will exit you from any menus you may be in. Stay safe and use caution when utilizing advanced features. See example spreadsheet here Before exiting ensure you SAVE the data and CONFIRM the % numbers are ever increasing in from element 0 to element 4. The Correction ratio must be between 0.8 and 1.2. Where to get Power Supplies, Gaskets, Nuts and Bolts Link Please take note that for optimal performance, it is crucial to rigidly mount or effectively isolate Vortex Flow Meters from vibration. Failure to do so may result in the transmission of vibrating energy to the Vortex Piezo Sensors, causing inaccurate readings. To achieve this, we recommend utilizing rigid mounts that are firmly attached to a solid base or effective vibration isolation techniques. To help you better understand this requirement, we have included some example settings for your study. Additionally, we have provided a video above that demonstrates how to enter the configuration modes.
