测量原理

涡街

主要特点

The flowmeter for accurate steam flow measurement with wet steam detection, available as compact or remote version. Integrated temp. measuring for mass/ energy flow of saturated steam. Suitable for a wide range of applications; optimized for steam applications. 

特点

Highest process safety – dualsens version enables redundant measurement. High availability – proven robustness, resistance to vibrations, temperature shocks & water hammer. No maintenance – lifetime calibration. Wet steam detection and measurement for DN 25 to 100 (1 to 4"). Inlet run compensation. 

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.
