Flow meter turndown ratio
WebThe results of Alicat’s recent turndown ratio test are illustrated in the following one-minute video. The unedited, real-time video monitors the actual flow rate of a 5-slpm mass flow controller that is paired with a 50-sccm mass flow meter rather than with a 5-slpm meter to observe just how low the Alicat controller could perform. At full ... A thermal mass flow meter has a turndown ratio of 1000:1. An orifice plate meter has a practical turndown ratio of 3:1. A turbine meter has a turndown ratio of 10:1. Rotary positive displacement meters have a turndown ratio of between 10:1 and 80:1, depending on the manufacturer and the application.
