Thermische Masse-Durchflussmesser

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.
