Product Description
Kurz 0025448 Model 454FTB-12-HT Single-Point Insertion Flow Meter
PN: 0025448
Model: 454FTB-12-HT
The Kurz 454FTB single‐point insertion flow meter for industrial gas flow measurement includes the qualities and features found in all Kurz constant temperature thermal flow meters that make them outperform all other currently available thermal mass flow meters, including:
- The highest repeatability, accuracy, and reliability available
- The fastest response to temperature and velocity changes in the industry
- Constant temperature thermal technology
- Interchangeable sensor and electronics (single circuit board)
- Continuous self‐monitoring electronics that verify the integrity of sensor wiring and measurements
- Sensor does not overheat at zero flow using a unique constant temperature control method and power limiting design
- Zero velocity as a valid data point
- Insensitive to left or right horizontal installations
- Completely field configurable using the local user interface or via a computer connection
- Supports HART, Profibus DP, and Modbus communication protocols
- User‐programmable correction factors to compensate for velocity profiles
- User-defined binary gas compositions or up to five multiple gas calibrations
- Velocity‐temperature mapping for wide ranging velocity and temperature
- Sensor Blockage Correction Factor (SBCF)
- Flexibility with transmitterattached or transmitter-separate designs
- Patented digital sensor control circuit (US 7,418,878)
Specifications:
The Kurz Series 454FTB is the premier single-point insertion thermal mass flow meter for industrial gas flow measurements. The 454FTB supports process temperatures from -40° C to 260° C and from -40°C to 500° C, process pressure ratings up to 300 PSIG, and a velocity range from 0 to 24,000 SFPM.
- Process Temperature Rating: The "HT" variant is rated for temperatures ranging from -40°C to 260°C (-40°F to 500°F).
- Pressure Rating: It can handle process pressures up to 300 PSIG (20 BARg).
- Velocity Range: Typically supports a velocity range from 0 to 24,000 SFPM (up to 70,000 SFPM in some configurations).
- Accuracy & Repeatability: It offers a high repeatability of 0.25% and temperature accuracy of ±(0.5% of reading + 1°C) for velocities above 100 SFPM.
- Sensor Construction: Uses an all-welded Alloy C-276 sensor for superior corrosion resistance and thermal isolation.
- Power Requirements: Operates on 24 VDC ±10% or 85-265 VAC (47/63 Hz) at a maximum of 24 watts.
- Enclosure: Features a polyester powder-coated aluminum dual-chamber enclosure rated IP66/NEMA 4X/7.
