It compensates in real time for changes of process conditions: temperature, pressure, flow direction and gas type. The innovative remote transmitter von t-mass F 500 maximizes installation flexibility and operational safety in demanding environments. 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 as well as gas mixtures in small line sizes • Inline version with DN 15 to 100 (1/2 to 4") • Bidirectional measurement; high measuring performance • Patented drift-free sensor with SIL 2 • Remote version with up to 4 I/Os • Backlit display with touch control and WLAN access • Standard cable between sensor and transmitter Device properties
