Endress+Hauser Proline Promass O 100 Coriolis Flowmeter
The Endress+Hauser Proline Promass O 100 is a robust high-pressure Coriolis flowmeter designed for premium-accuracy liquid and gas measurement, particularly for demanding oil and gas applications. The instrument is designed to withstand high process pressures and harsh offshore conditions while maintaining reliable measurement performance.
A major feature of Promass O 100 is its combination of a high-pressure Coriolis sensor, Super Duplex measuring tube and ultra-compact transmitter. This provides high mechanical strength and resistance to stress corrosion cracking while keeping the overall measurement system compact and easy to integrate.
High-Pressure Coriolis Flow Measurement
Promass O 100 is designed for applications where high process pressure and accurate flow measurement are critical.
The maximum process pressure reaches:
PN 250 / Class 1500
This makes the Promass O 100 suitable for demanding high-pressure process applications in the oil and gas industry.
The Coriolis measuring principle directly measures mass flow and is largely independent of fluid properties such as viscosity and density.
Premium Accuracy for Liquids and Gases
Promass O 100 provides accurate measurement of both liquids and gases.
Key measurement performance includes:
Liquid mass flow: ±0.10% standard
Liquid mass flow: ±0.05% optional
Liquid volume flow: ±0.10%
Gas mass flow: ±0.35%
Liquid density: ±0.0005 g/cm³
The optional ±0.05% liquid mass flow accuracy makes Promass O 100 suitable for applications requiring premium measurement performance.
Designed for Oil and Gas Applications
Promass O 100 is specifically designed for the oil and gas industry, where high pressure, mechanical integrity, corrosion resistance and measurement reliability are essential.
Typical applications include:
Oil and gas processing
High-pressure hydrocarbon measurement
Offshore production
Offshore process facilities
Gas measurement
Liquid hydrocarbon measurement
High-pressure process monitoring
Custody-related measurement applications, depending on configuration and approval requirements
The sensor is designed for offshore conditions and provides high resistance to stress corrosion cracking, an important consideration for demanding oil and gas environments.
Super Duplex Measuring Tube
The Promass O 100 measuring tube is available in 25Cr Duplex / Super Duplex stainless steel, 1.4410 (UNS S32750).
The process connection can also be supplied in 25Cr Duplex, 1.4410 (F53), depending on configuration.
The Super Duplex construction provides excellent resistance to corrosion and stress corrosion cracking, making it particularly suitable for demanding offshore and high-pressure applications.
Wide Measuring Range
Promass O 100 covers nominal diameters from approximately DN80 to DN150 (3 to 6") according to the current product specifications.
The maximum measuring range reaches:
800,000 kg/h (29,400 lb/min).
This allows the instrument to handle high-capacity process flow applications while maintaining the advantages of Coriolis mass flow measurement.
Multivariable Measurement
Promass O 100 provides multiple process variables from a single measurement point.
Depending on configuration, measured variables include:
Mass flow
Volume flow
Corrected volume flow
Density
Reference density
Temperature
Concentration
This multivariable functionality can reduce the number of separate instruments required and provide additional information for process monitoring and control.
Ultra-Compact Transmitter
The Promass O 100 features an ultra-compact transmitter housing, providing full transmitter functionality while minimizing installation space.
This makes it particularly useful for:
Offshore installations
Skid-mounted systems
Compact process packages
Oil and gas equipment
Applications with limited instrumentation space
The transmitter includes an integrated web server, allowing device configuration through a web browser without requiring additional hardware or software.
High Protection for Harsh Environments
The transmitter housing is designed for demanding industrial and offshore environments.
Depending on configuration, the device provides IP66/67 protection, with IP69 available as an option. The transmitter housing can also be supplied in corrosion-resistant 316L stainless steel.
High-Temperature Process Measurement
Promass O 100 supports a medium temperature range of:
-40 to +205 °C (-40 to +401 °F).
This wide temperature range allows the instrument to be used in demanding high-pressure process environments.
Flexible Digital Communication
Promass O 100 supports several communication technologies for integration into process automation systems, including:
HART
Modbus RS485
EtherNet/IP
PROFIBUS DP
PROFINET
The standard output configuration includes 4–20 mA HART and a passive pulse/frequency/switch output.
This allows integration into PLC, DCS, SCADA and other industrial automation systems.
Space-Saving Installation
The Coriolis measurement principle means that Promass O 100 does not require conventional inlet and outlet straight pipe runs.
This provides additional flexibility when designing process piping and can help reduce the footprint of the flow measurement installation.
Heartbeat Technology
Promass O 100 incorporates Endress+Hauser Heartbeat Technology for integrated verification and diagnostics.
Heartbeat Technology supports measurement verification and measurement traceability, helping users maintain reliable flow measurement and improve process safety without unnecessary removal of the instrument from the process.
Safety and Industry Approvals
Promass O 100 is available with a broad range of approvals and certificates for demanding industrial and offshore applications.
Depending on configuration, these include:
