FKM"    "Field of application
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

Device properties

Insertion version for DN 80 to 1500 (3 to 60"")
