2445 High Temperature Portable Flow Meter
Brand: Kurz InstrumentsThe Model 2445 High-Temperature Portable Flow Meter is designed for very high temperatures (500° C) applications, such as coal-fired power plant stacks, and primary and secondary air ducts. The Model 2445 is available in five fixed lengths from 24" to 72" with a 3/4" diameter sensor support. The rugged all-welded construction and large size of the Model 2445 make it ideal for dirty and corrosive environments.
Features- Excellent sensitivity to low velocities
- Insensitive to dirt and particulates in the flow stream
- User-configurable low velocity cut-off, reference conditions, time constraints, and flow area
- Velocity‐temperature mapping for wide ranging velocity and temperature
- Sensors do not overheat at zero flow by using a unique constant temperature control method and power limiting design.
- Sensor lead-length independent circuitry
- Insensitive to installation angle
