Field of application

The t-mass 65F inline device is specially 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.

Measuring principle is characterized by a high operable flow range and direct mass flow measurement
Measurement of gases and gas mixtures in small line sizes.

Device properties

Inline version: nominal diameter DN 15 to 100 (1/2 to 4")
Process pressure up to PN 40, Class 300
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 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
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
