| 测量原理 | 热式 |
| 主要特点 | The flowmeter for cost‐effective measurement and easy monitoring of utility gases. Suitable for air, nitrogen, carbon dioxide and argon in small line sizes.
|
| 特点 | Optimal process monitoring – easy measurement even at low pressures and flow velocities. Costeffective measurement – easy installation, negligible pressure loss and maintenance‐free. Reliable flow trending – multivariable measurement. Inline version: nominal diameter DN 15 to 50 (? to 2").
Process pressure up to PN 40, Class 300.
|
| Transmitter features | Fast and efficient commissioning – guided operating menus. High plant availability – self‐diagnostics and error monitoring. Automatic recovery of data for servicing. Device in compact version with DC 24 V power supply. 4‐20 mA HART, pulse/frequency/switch output.
