| 測量原理 | 科氏力 | |
| 主要特點 |
The genuine loop‐powered robust flowmeter for demanding applications. Highest measurement perbance for liquids and gases under varying, demanding process conditions. |
|
| 特點 |
Highest process safety – immune to fluctuating and harsh environments. Fewer process measuring points – multivariable measurement (flow, density, temperature). Space‐saving installation – no in/outlet run needs. Mass flow: measured error ±0.1 %. Medium temperature up to 205 °C (401 °F). |
|
| Transmitter features |
Convenient device wiring – separate connection compartment. Safe operation – no need to open the device due to display with touch control, background lighting. Integrated verification – Heartbeat Technology. Loop‐powered technology. Robust dual- compartment housing. |
