| 測量原理 | 超聲波 | |
| 主要特點(diǎn) |
Flowmeter with automatic frequency scan for max. measuring perbance with a wide range of analog and digital outputs. Clamp-on flow measurement of process water, saltwater, deminerialized water, drinking water and wastewater. |
|
| 特點(diǎn) |
Low capital investment – cost-effectiveness increases with pipe diameter (up to DN 4000). No additional leakage paths – external measurement from outside the pipe. Process transparency – diagnostic capability. Medium temperature: –20 to +80 °C (-4 to +176 °F). Degree of protection IP68 (Type 6P enclosure) for pipes under water. |
|
| Transmitter features |
Highest perbance – extended functionality and diagnostics. Flexible data transfer options – numerous communication types. Automatic recovery of data for servicing. Aluminium transmitter housing. 4‐line backlit display with touch control. |
