In-Line Mass Flow Sensor – 504FTB Series

Kurz Instruments, Inc.

The highest repeatability, accuracy, and reliability available
The fastest response to temperature and velocity changes in the industry
Constant temperature thermal technology
High turndown ratio
Low flow noise

The Kurz 504FTB in-line thermal mass flow meter for applications ranging from vacuum service up to 300 PSIG includes the qualities and features found in all Kurz constant temperature thermal flow meters that make them outperform all other currently available thermal mass flow meters, including HART, Profibus DP, and Modbus, and includes patented digital sensor control circuitry. The meter is capable of reading low flows during start-up, shut-down, or obstruction events and includes continuous self-monitoring electronics to verify sensor wiring and measurements. The 504FTB is suitable for a wide range of applications including process & specialty gases, compressed air, fuel flow, natural gas metering, solvent & VOC recovery, NOx control, flow calibration, as well as air sampling.
