Endress & Hauser t-mass 65I is insertion type Thermal mass flow meter designed for the direct mass flow measurement for industrial gases and compressed air. The turndown ratio of typically 100:1, it can measure accurately operational flow rates and offline leakage. The integrated gas engine allows you to configure the device for 20 freely selectable gases also the insertion version is suitable for large pipelines or rectangular ventilation ducts.
