K-BAR 2000B Series Multipoint Insertion Flow Meter
Brand: Kurz Instruments
K-BAR 2000B multipoint insertion flow meter uses up to four sensors for measurement redundancy and to ensure accuracy. Its rugged design withstands the high stress and high vibrations found in large industrial stacks and ducts that commonly have wide-ranging velocity and temperature profiles. The K-BAR 2000B supports process temperatures up to 260° C or up to 500° C.
Features- Ideal for large stacks and ducts with non-uniform velocity profiles
- Capable of reading low flows that occur during start-up, shut-down, or obstruction events
- Easy installation and no maintenance
- Sensors are resistant to dirt and corrosion.
- Individual sensor optimization for flow profile variations
- Interchangeable sensor and electronics — no matched sets
- Continuous self‐monitoring electronics that verify the integrity of sensor wiring and measurements
- Sensors do not overheat at zero flow by using a unique constant temperature control method and power limiting design
- Zero velocity as a valid data point
- User-programmable dual gas mix interpolation
- User‐programmable correction factors to compensate for velocity-dependent profile shifts
- Velocity‐temperature mapping for wide ranging velocity and temperature
- Supports HART, Profibus DP, and Modbus communication protocols
