Flow Meter Selection Chart

Choosing the Right Scientific Flow Meter for Your Application

Selecting the right flow meter for your application doesn’t have to be difficult. With over 40 years of experience and 100,000 flow meters installed, Sierra has a line of accurate flow meters flexible enough to handle a variety of application conditions. These scientific meters are capable of measuring low flows (0 to 0.1 sccm), high flows (to 1000 slpm), corrosive gases, low pressure drop (4.5 psid), high pressure (up to 5000 psig). In addition, these capillary thermal meters feature multi-gas capability, a small footprint and easy systems integration. Watch Video. 

Find the right flow meter for your application using the chart below.  Need to measure even higher gas flow rates? Sierra also manufactures industrial thermal mass flow meters.
