Thông số kỹ thuật
- Mass or volumetric flow monitoring of gases, liquids and steam
- Inline 1 to 8 inches (25 to 203 mm)
- Accuracy:
+ Mass flow: +/- 1.0% of reading over a 30:1 range (liquids); +/- 1.5% of reading over a 30:1 range (gas & steam)
+ Volumetric: +/- 0.7% of reading over a 30:1 range (liquids); +/- 1.0% of reading over a 30:1 range (gas & steam)
- Flow range (30:1 Turndown):
+ Liquids:
1 ft/s (0.3 m/s) Velocity Minimum
