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. At the same time, the system also measures corrected volume flow,
temperature and calculated density.
Examples:
• Compressed air
• Oxygen
• Nitrogen
• Carbon dioxide
• Bio gas, etc.
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
Measuring range The measuring range is dependent on the gas selection, line size and use of flow conditioner. Each
meter is individually calibrated on air and mathematically converted to suit the customer specific
gas, where required.
The tables below define the ranges available for air without flow conditoner. Please refer to your
Hauser representative or to Applicator (the Hauser sizing and selection software)
for other gases and process conditions.
