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
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.
