Endress+Hauser Proline

Endress+Hauser Proline t-mass 65I Therm

High performing flowmeter with intelligent and dynamic adaptation to changing process conditions

The t-mass 65I was designed for the direct mass flow measurement of industrial gases and compressed air. With a turndown of typically 100:1 it can measure accurately operational flow rates and off line leakage. The integrated gas engine allows the customer to configure the device for 20 freely selectable gases. The t-mass 65I insertion version is suitable for large pipelines or rectangular ventilation ducts.

Benefits

  • Measurement of gases and gas mixtures in circular piping or rectangular ducts
