Insertion Thermal Mass Flow Sensor – 454FTB 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
Interchangeable sensor and electronics (single circuit board) — no matched sets
Continuous self‐monitoring electronics that verify the integrity of sensor wiring and measurements
Sensor does not overheat at zero flow using a unique constant temperature control method and power limiting design
Zero velocity as a valid data point
Insensitive to left or right horizontal installations

The Kurz 454FTB single‐point insertion flow meter for industrial gas flow measurement 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 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 454FTB is suitable for a wide range of applications including primary, secondary, tertiary & overfire air, stack & flue gas, flare gas, boilers & recovery boilers, industrial and process gases, compressed air, coal pulverizer air, cement plants, aeration air and treated biogas, as well as EPA & AMS emissions monitoring.
