thermal gas mass flow meter

Features: 1. Apply high stability and patented technology platinum RTD sensor 2. Uses proprietary technology "balanced structure package", medium temperature self-compensation. 3. Proprietary algorithms; can achieve high linearity, high repeatability, high precision. 4. Range ratio 1000:1, also can be expanded according to user requirements. 5. Enables measurement of small flow large diameter, minimum flow rate can be measured as low as zero, resolution0.001m/s. 6. No moving parts, vibration can be neglected. 7. Straight pipe less demanding 1-2D. 8. Unrelated with the medium temperature and pressure. 9. Proprietary high-temperature method, medium temperature up to +510 . 10. Humidity algorithm used to achieve high precision measurement. 11. Flow signal enter 12-point dynamic correction, built-in 10-point amendment. 12. Dynamic on-line correction current / voltage output. 13. Dont sensitive to dust and other small particles. 14. On-line continuous flow, easy handling and maintenance.
