K-BAR-2000B

K-Bar 2000B Insertion mass flow meter

The K-BAR 2000B utilizes the patented B-Series technology tomeasure gas velocity and temperature at several points across thespan. Using the FD2 Fast Dual Metal Clad™ sensor, the K-BAR2000B calculates the mass, velocity, and temperature at each point,and the Series 155 Mass Flow Computer uses this data to provide theaverage velocity and average temperature within the process. It isideal for ducts and stacks that have wide-ranging velocity andtemperature profiles. Temperature rating is 260°C and500°C.
