Critical Technical Advantages
-
Large Pipe Versatility: The insertion design is suitable for pipe sizes from DN 80 up to DN 1500 (3 to 60 inches). This provides a single, scalable solution for large-diameter headers where inline meters would be prohibitively expensive or heavy.
-
Direct Mass Flow Measurement: The t-mass I 300 measures the mass of gas molecules directly through thermal dispersion. This eliminates the need for separate temperature or pressure compensation, simplifying both the installation and the data processing requirements for energy management.
-
Intelligent Gas Engine: The device includes a library of 21 standard gases and allows for the definition of custom gas mixtures. The Gas Engine compensates in real time for changes in gas composition and process conditions, maintaining accuracy even if the gas quality fluctuates.
-
Patented Drift-Free Sensor: Engineered for durability and stability, the sensor is SIL 2 certified. Its robust design is specifically built to handle the mechanical stresses of high-velocity gas streams while maintaining consistent performance over time.
-
Heartbeat Technology: Integrated diagnostics and verification allow for a documented health check without process interruption. This feature ensures that the device remains within its specified calibration limits, supporting regulatory compliance and quality audits.
-
Seamless System Integration: The 300-series transmitter offers advanced connectivity, including WLAN access and multiple freely configurable I/Os. This allows for remote operation and easy integration into existing PLC or SCADA systems via modern fieldbus protocols.
