Proline t-mass F/I 300/500 – The thermal mass flowmeter with long-term stability and a keen sense for utility gases

The Thermal Flow Measuring Principle

  • Proline t-mass I 500 – Insertion version made of stainless steel for pipes/ducts up to DN 1500 (60")
  • Proline t-mass I 500 with stainless steel connection housing and remote transmitter
  • Discover t-mass F and I via 3D QR code

Insertion flowmeter with long-term stability as remote version with up to 4 I/Os

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. The innovative remote transmitter of t-mass I 500 maximizes installation flexibility and operational safety in demanding environments. Heartbeat Technology ensures measurement reliability and compliant verification.
