Field of application

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.

  • Measuring principle is characterized by a high operable flow range and direct mass flow measurement

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

Device properties

  • Insertion version for nominal diameter DN 80 to 1500 (3 to 60")

  • Medium temperature up to +130 °C (266 °F)

  • High accuracy: ±1.5 % o.r. (10 to 100 % o.f.s.)

  • Device as compact or remote version

  • 4-20 mA HART, PROFIBUS PA/DP, Modbus RS485, FF

  • Worldwide approvals (Hazardous areas)

Benefits

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

  • Plant safety – high accuracy and repeatability for a wide range of utility and process gases

  • Cost-effective measurement – easy installation, negligible pressure loss and maintenance-free

  • Reliable flow trending – multivariable measurement

  • Fast and efficient commissioning – guided operating menus

  • High plant availability – self-diagnostics and error monitoring

  • Automatic recovery of data for servicing
