t-mass 65F

Thermal

High-performing flowmeter with intelligent and dynamic adaptation to changing process conditions.
Measurement of gases and gas mixtures in small line sizes.

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.
Inline version: nominal diameter DN 15 to 100 (½ to 4"). Process pressure up to PN 40, Class 300. High accuracy: ±1.5 % o.r. (10 to 100 % o.f.s.).

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