| 測量原理 | 渦街 |
| 主要特點(diǎn) | The flowmeter with a cost‐effective wafer design, available as compact or remote version. Integrated temperature measurement for mass/energy flow of saturated steam. For all basic applications and for 1‐to‐1 replacement of orifice plates.
|
| 特點(diǎn) | Easy alignment of the sensor – included centering rings. High availability – proven robustness, resistance to vibrations, temperature shocks & water hammer. No maintenance – lifetime calibration. Face‐to‐face length of 65 mm (2.56 in). No flanges.
|
| 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. Display module with data transfer function. Robust two‐chamber housing.
