| 测量原理 | 科氏力 |
| 主要特点 | The chemically resistant single‐tube flowmeter with extended transmitter functionality. Highly accurate measurement of liquids and gases in applications requiring highest corrosion resistance.
|
| 特点 | Maximum safety for chemically aggressive fluids – corrosionresistant wetted parts. Fewer process measuring points –multivariable measurement (flow, density, temperature). Spacesaving installation – no in/outlet run needs. Measuring tube made of Tantalum, Zirconium. Nominal diameter: DN 8 to 50 (3?? to 2").
|
| Transmitter features | Quality – software for filling & dosing, density & concentration, advanced diagnostics. Flexible data transfer options – numerous communication types. Automatic recovery of data for servicing. 4‐ line backlit display with touch control. Device in compact or remote version.
