t-mass 65I

Thermal

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

Flexible device configuration to suit the application – integrated "Gas Engine" functionality. For demanding applications – user-definable gas mixtures, high repeatability and accuracy. Automatic recovery of data for servicing.
Device as compact or remote version. 4-20 mA HART, PROFIBUS PA/DP, Modbus RS485, FF. Worldwide approvals (Hazardous areas).
