As with any flowmeter, knowing the application information upfront helps with proper sizing and selection of a rotameter. The flow rate you’ll be operating at is a good starting point.

The basic information we like to know to get started is:

• Fluid (Liquid / Gas):
• Flow Rate / Range:
• Operating Pressure:
• Operating Temperature:
• Local Indication Only -or- Remote Indication Also:

Some more in-depth questions would be:

• Metal -or- Glass:
• Connection Size / Type:
• Min / Max Pressure:
• Min / Max Temperature:
• Desired Accuracy:
• Allowable Pressure Drop:

Global web based sizing tools are now utilized to ensure accurate and consistent results, but that won’t stop you from finding some old slide rules lying around the Ernie Graves Company. If there’s anyone you can rely on for assistance with this it’s us. We’ve been specifying and supplying variable area rotameters for more than five decades.

We’ll get to capacitance manometer selection next, so stay tuned……
