科里奥利质量流量
The single‐tube flowmeter for smallest flow quantities with a compact or remote transmitter. Measuring accurately smallest quantities of liquids and gases for continuous process control.
Highest process safety – self‐drainable measuring tube design. Fewer process measuring points – multivariable measurement (flow, density, temperature). Space‐saving installation – no in/outlet run needs. Nominal diameter: DN 1 to 4 (¹⁄?6?0?6?2 to ¹⁄?6?6"). Process pressure up to 400 bar (5800 psi).
Cost‐effective – dedicated design for standard applications. Safe operation – display provides easy readable process information. Fully industry compliant – IEC/EN/NAMUR. 2‐line backlit display with push buttons. Device in compact or remote version.
