Kurz Instruments – Portable Thermal Flow Meter

Kurz Instruments Logo

The 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. It includes an all-metal display module, battery charger, carrying case, and several accessories.

The Model 2444 Heavy Industrial Portable Flow Meter provides the flexibility for a wide variety of field measurement applications because of multiple 16″ sections that can connect up to 64.5″ long. The Model 2444 works with high temperatures up to 200°C. It includes an all-metal display module, battery charger, carrying case, and several accessories.

Additional models are available incorporating design features optimized for unique applications, in turn balancing demands. One such model is the 2440 series which is specialized for laboratory and HVAC applications.

These models include a programmable data storage feature which is useful for protecting your data from being lost, with a convenient retrieval capability.

Features & Benefits

  • Portable Thermal Mass Technology: Offers precise, repeatable gas flow measurements in velocity, volume, and mass—ideal for field testing, calibrations, and surveys.
  • High Accuracy & Repeatability: ±(0.5% of reading + 1°C) for temperatures; ±0.25% repeatability ensures consistent, dependable measurements.
  • Fast Response Time: 1-second response for velocity or temperature changes—critical for dynamic flow diagnostics.
  • Wide Velocity Range: Measures from 0 to 12,000 SFPM—suitable for very low to high air/gas flows.
  • Internal Data Logging (1,500 Points): Enables velocity traverses and historical data collection without external tools.
  • Constant Temperature Control: Prevents sensor overheating at zero flow and ensures long sensor life.
  • Field-Configurable via Display/Keypad: No PC required—users can adjust settings, units, cutoff points, and calibration preferences directly.
  • Modbus/RS-232/RS-485 and 4–20 mA Outputs: Simplifies integration with data systems and SCADA; analog outputs support standard control inputs.
  • CE Certified: Meets EN emissions, immunity, and surge standards—suitable for global industrial deployment.
  • Battery Powered (2.5 hr recharge): Operates independently of line power—ideal for mobile/field service work.
