The Kurz 504FTB In-Line Flow Meter provides a plug-and-play solution for a wide variety of applications and delivers high accuracy, reduced costs, and no maintenance. Flow sensitivity is increased because the sensors are placed directly in the flow stream without the protection needed with insertion meters.

There are 10 models available in pipe diameters ranging from 3/8” to 4”. The Kurz power-limiting design and constant temperature sensor control prevent sensor overheat at zero flow.


The 504FTB is ideal for high-pressure gas flow measurements and includes the qualities and features found in all Kurz thermal mass flow meters.

  • Ideal for process and specialty gases
  • Sensors resistant to dirt and corrosion
  • Wide turndown capability
  • Zero velocity as a valid data point
