504FTB Series In-Line Flow Meter
Brand: Kurz Instruments
The Series 504FTB in-line flow meter is designed for applications where flow disturbances or line size changes are not an issue.
The 504FTB is available in 10 models for inline sizes from 1/2" to 4" pipes.
Features- Ideal for process and specialty gases
- Sensors resistant to dirt and corrosion
- Supports HART, Profibus DP, and Modbus communication protocols
- User-defined binary gas compositions or up to five multiple gas calibrations
- Sensor lead length independent circuitry
- Very low flow noise
- High turndown ratio.
- Sensors do not overheat at zero flow using a unique constant temperature control method and power limiting design
- Supports HART, Profibus DP, and Modbus communication protocols
- Zero velocity as a valid data point
