10.1 Technical data at a glance
10.1.1 Applications
The measuring device described in these Operating Instructions is to be used only for measuring the
mass flow rate of gases (e. g. kg, Nm
3
scf). At the same time, the system also measures gas
temperature. The measuring device can be configured to measure a standard range of pure gases or
gas mixtures.
Examples:
•Air
• Oxygen
• Nitrogen
• Carbon Dioxide
•Argon, etc.
The use with corrosive, saturated or unclean gases should be treated with caution (contact your
Endress+Hauser sales representative). The use with unstable gases or gases not deemed to be
suitable by Endress+Hauser must be avoided. The measuring device is not designed to be used with
liquids or fluids in the liquid phase.
Resulting from incorrect use or from use other than that designated, the operational safety of the
measuring devices can be jeopardized. The manufacturer accepts no liability for damages being
produced from this.
10.1.2 Function and system design
Measuring principle Mass flow measurement by the thermal dispersion principle.
Measuring system The t-mass 65 flow measuring system consists of the following components:
• t-mass 65 transmitter
• t-mass F, t-mass I sensor
Two versions are available:
• Compact version: transmitter and sensor form a single mechanical unit.
• Remote version: transmitter and sensor are installed separately.
10.1.3 Input
Measured variable • Mass flow
• Gas temperature
• Gas heat flow
Measuring range The measuring range is dependent upon:
• Gas
•Pressure
•Temperature
• Cross-sectional area of pipe or duct
• Use of flow conditioner (t-mass F sensor)
Please refer to Applicator, the Endress+Hauser sizing and selection software, for calculation of the
measuring range.
