Promass 84O

Coriolis

The robust high‐pressure flowmeter with custody transfer functionality. For premium accuracy at highest process pressures; fully suitable for on/offshore conditions.

Maximum safety – highest resistance to stress corrosion cracking. Fewer process measuring points – multivariable measurement (flow, density, temperature). Space‐saving installation – no in/outlet run needs. Measuring tube in 25Cr Duplex, 1.4410 (UNS S32750). Process pressure up to PN 250, Class 1500.

Quality – designed for custody transfer; featuring worldwide recognized metrological approvals. Flexible data transfer options – numerous communication types. Automatic recovery of data for servicing. 4‐line backlit display with touch control. Device in compact or remote version.
