Endress+Hauser Proline Promass O 500 Coriolis Flowmeter
The Endress+Hauser Proline Promass O 500 is a robust high-pressure Coriolis flowmeter designed for accurate liquid and gas measurement under demanding process conditions. It is particularly suited to the oil and gas industry, including applications where high process pressure, offshore suitability, corrosion resistance and reliable measurement are essential.
Unlike the compact Promass O 100 and the integrated-transmitter Promass O 300, the Promass O 500 uses a remote transmitter configuration with up to 4 configurable I/Os. This provides greater flexibility when the sensor and operating interface need to be installed separately.
High-Pressure Coriolis Flow Measurement
Promass O 500 is engineered for premium-accuracy measurement at high process pressures.
The maximum process pressure is:
PN 250 / Class 1500
This makes the flowmeter suitable for high-pressure process lines, oil and gas facilities and demanding offshore applications.
Accurate Liquid and Gas Measurement
Promass O 500 uses the Coriolis measuring principle to directly measure mass flow while also providing additional process variables.
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
This makes Promass O 500 suitable for applications requiring reliable and highly accurate measurement of liquids and gases.
Super Duplex Construction
The measuring tube is manufactured from 25Cr Duplex / Super Duplex stainless steel, 1.4410 (UNS S32750), with the process connection also available in 25Cr Duplex / Super Duplex, 1.4410 (F53).
This construction provides high resistance to stress corrosion cracking and supports reliable operation in demanding oil and gas and offshore environments.
Designed for Offshore Conditions
Promass O 500 is designed for applications where high pressure and offshore environmental conditions are critical.
Its combination of Super Duplex materials, high pressure capability and available marine/offshore approvals makes it suitable for demanding installations in:
Offshore oil and gas production
Oil and gas processing
High-pressure hydrocarbon pipelines
Gas processing facilities
Offshore process skids
Marine process systems
Large-Diameter Flow Measurement
Promass O 500 supports nominal diameters from:
DN 80 to DN 250 (3 to 10")
The maximum measuring range reaches:
800,000 kg/h (29,400 lb/min).
This makes it suitable for relatively large process pipelines and high-capacity flow measurement.
Multivariable Process Measurement
Promass O 500 provides multiple process variables from a single measuring point:
Mass flow
Volume flow
Corrected volume flow
Density
Reference density
Temperature
Concentration
The multivariable capability can reduce the number of separate instruments required for process monitoring and provide additional information for process control.
Remote Transmitter with Up to 4 I/Os
The main feature differentiating the Promass O 500 is its remote transmitter configuration.
The transmitter can be installed separately from the sensor using a standard cable, providing greater freedom when designing the instrumentation layout.
The transmitter supports:
Up to 4 configurable I/Os
Backlit display
Touch control
WLAN access
Flexible fieldbus communication
Process and diagnostic information access
Freely configurable I/O functionality
This makes Promass O 500 particularly suitable for installations where the measuring point and operating location need to be separated.
Flexible Communication and Automation Integration
Promass O 500 provides flexible communication and I/O options for integration into modern industrial automation systems.
Depending on configuration, it can support communication technologies such as:
HART
PROFIBUS
Modbus
PROFINET
Ethernet-based communication
Ethernet-APL
This allows integration with PLC, DCS, SCADA and plant asset management systems.
Space-Saving Installation
The Coriolis measuring principle does not require conventional inlet and outlet straight pipe runs.
This simplifies piping design and can help reduce the installation footprint, which is particularly valuable in offshore facilities, process skids and compact high-pressure installations.
Process Temperature and Pressure
Promass O 500 is designed for demanding process conditions.
Key specifications include:
Medium temperature: -40 to +205 °C (-40 to +401 °F)
Maximum process pressure: PN 250 / Class 1500
Nominal diameter: DN 80 to DN 250
Maximum measuring range: 800,000 kg/h
Heartbeat Technology
Promass O 500 incorporates Endress+Hauser Heartbeat Technology for integrated device verification and diagnostics.
Heartbeat Technology supports measurement verification and helps users maintain reliable measurement performance without unnecessary removal of the flowmeter from the process.
