The t-mass 65I is suitable for the direct mass flow measurement of industrial gases and compressed air. By turning down the typical turndown ratio of 100:1, operating flow rates and offline leakage can be measured accurately. The built-in gas engine allows users to configure the device and freely select from 20 gases for measurement. The insertion-type flowmeter t-mass 65I is suitable for large pipes and rectangular air ducts.
