Field of application
The patented sensor design of t-mass F provides unprecedented measurement stability in thermal inline mass flow measurement. It compensates in real time for changes of process conditions: temperature, pressure, flow direction and gas type. Its compact transmitter offers high flexibility in terms of operation and system integration: access from one side, remote display and improved connectivity options. Heartbeat Technology ensures measurement reliability and compliant verification.
Measuring principle is characterized by a high operable flow range and direct mass flow measurement
Measurement of utility and process gases as well as gas mixtures in small line sizes
Device properties
Inline version with DN 15 to 100 (1/2 to 4")
Bidirectional measurement; high measuring performance
Patented drift-free sensor with SIL 2
Compact dual-compartment housing with up to 3 I/Os
Backlit display with touch control and WLAN access
Remote display available
Benefits
Flexible, convenient programming based on 21 standard gases or freely definable gas mixtures thereof
High level of process control – premium measurement accuracy and repeatability
Reliable monitoring – detection of process disturbances and reverse flow
Easy maintenance – removable sensor
Full access to process and diagnostic information – numerous, freely combinable I/Os and fieldbuses
Reduced complexity and variety – freely configurable I/O functionality
Integrated verification – Heartbeat Technology
