K-BAR 2000B utilizes the Kurz MFTB Technology. This includes a fast, powerful microprocessor and patent pending circuit that measures both the gas velocity and the gas temperature using only two sensor elements on the “FD2” Fast Dual Metal Clad™ sensor. It calculates the mass velocity and temperature at each point, thereby allowing the Series 155 Mass Flow Computer to present the average velocity and average temperature. It is ideal for ducts/stacks having wide-ranging spatial and time varying velocity and temperature profiles. Temperature ratings of 260°C and 500°C.
