Proline Promass 84O
Coriolis flowmeter

The robust high-pressure flowmeter with custody transfer functionality

  • Coriolis flowmeter - Proline Promass 84O ©Endress+Hauser

Promass 84O is designed to meet the requirements of custody transfer measurement in the oil and gas industry. It is the first mass flow meter to combine pressure and corrosion resistance without compromise. Even under the most difficult process requirements – such as dealing with pressures up to 258 bar (3742 psi) or measuring hydrocarbons with highly aggressive hydrogen sulfide (H2S) – the Promass O offers maximum safety.


  • 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

  • Quality – designed for custody transfer; featuring worldwide recognized metrological approvals

  • Flexible data transfer options – numerous communication types

  • Automatic recovery of data for servicing

Область применения

  • Measuring principle operates independently of physical fluid properties such as viscosity or density

  • For premium accuracy at highest process pressures; fully suitable for on/offshore conditions.

Device properties

  • Measuring tube in 25Cr Duplex, 1.4410 (UNS S32750)

  • Process pressure up to PN 250, Class 1500

  • Nominal diameter: DN 80 to 150 (3 to 6")

  • 4-line backlit display with touch control

  • Device in compact or remote version

  • Phase-shifted pulse, HART, Modbus RS485
