Field of application

Endress Hauser’s

The patented sensor design of t-mass I provides unprecedented measurement stability in thermal insertion 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 enables 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 and gas mixtures in circular piping or rectangular ducts
• Insertion version for DN 80 to 1500 (3 to 60″)
• 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
