Endress+Hauser Proline Promass Q 500 Coriolis Flowmeter
The Endress+Hauser Proline Promass Q 500 is a high-performance Coriolis flowmeter designed for demanding flow measurement applications where accuracy, process reliability and installation flexibility are essential. It is particularly suited to custody transfer, density measurement and liquid applications containing entrained gas.
Promass Q 500 combines the advanced Multi-Frequency Technology (MFT) sensor with a remote transmitter architecture. This combination provides accurate measurement under challenging process conditions while allowing the transmitter to be installed separately from the sensor for greater installation flexibility.
High-Accuracy Coriolis Measurement
Promass Q 500 provides accurate measurement of mass flow, volume flow and density.
Key measurement performance includes:
Liquid mass flow: ±0.10% standard
Liquid mass flow: ±0.05% with PremiumCal
Liquid volume flow: ±0.10%
Gas mass flow: ±0.25%
Liquid density: ±0.0002 g/cm³
Optional density accuracy: ±0.0001 g/cm³
This high measurement performance makes Promass Q 500 suitable for applications where measurement accuracy directly influences product accounting, process control or product quality.
Optimized for Custody Transfer
Promass Q 500 is designed as a high-performance solution for custody transfer measurement.
Its combination of highly accurate mass flow, volume flow and density measurement makes it suitable for commercial measurement and metering applications involving valuable liquid products.
Typical applications include:
Custody transfer metering
Hydrocarbon measurement
Liquid product transfer
Loading and unloading systems
Metering skids
Oil and gas applications
Fiscal flow measurement
Process measurement systems
The exact custody transfer approval depends on the selected configuration and applicable regional requirements.
Multi-Frequency Technology for Entrained Gas
A key advantage of the Promass Q 500 is its Multi-Frequency Technology (MFT).
The technology is specifically optimized for liquid applications where entrained gas may be present. Entrained gas can create significant challenges for conventional flow measurement because gas bubbles can affect the stability and accuracy of the measurement.
Promass Q 500 is designed to maintain high measurement performance in challenging liquids containing entrained gas, making it particularly useful for applications such as bitumen measurement and hydrocarbon transfer.
Accurate Density Measurement
Promass Q 500 provides highly accurate liquid density measurement in addition to flow measurement.
The instrument can provide multiple process variables from a single measurement point:
Mass flow
Volume flow
Corrected volume flow
Density
Reference density
Temperature
Concentration
The optional density measurement accuracy can reach ±0.0001 g/cm³, supporting demanding applications where density is an important process or commercial parameter.
Wide Measuring Range
Promass Q 500 is available in nominal diameters from:
DN 25 to DN 250 (1 to 10")
The maximum measuring range reaches:
2,400,000 kg/h (88,183 lb/min).
This wide range allows the flowmeter to be used in both medium-capacity and high-capacity industrial flow measurement systems.
Remote Transmitter for Flexible Installation
The main configuration advantage of the Promass Q 500 is its remote transmitter.
The sensor and transmitter can be installed separately, providing greater flexibility when the measuring point is located in an area with limited access or demanding environmental conditions.
The transmitter provides:
Up to 4 configurable I/Os
Backlit display
Touch control
WLAN access
Remote display option
Flexible fieldbus communication
Access to process and diagnostic information
Freely configurable I/O functionality
The remote design makes Promass Q 500 particularly suitable for metering skids, process plants and installations where convenient transmitter access is important.
High Turndown and Low Pressure Loss
Promass Q 500 is designed for high turndown through a low pressure loss and low zero point.
This allows the flowmeter to maintain useful measurement performance across changing flow conditions and makes it suitable for processes with significant variations in operating flow rate.
Cryogenic and Wide Temperature Applications
Promass Q 500 supports a wide medium temperature range.
Standard temperature range:
-50 to +205 °C (-58 to +401 °F)
Optional cryogenic configuration:
-196 to +150 °C (-321 to +302 °F).
This allows Promass Q 500 to be considered for selected cryogenic liquid measurement applications in addition to conventional process applications.
High Process Pressure Capability
The maximum process pressure is:
PN 100 / Class 600 / 63K.
The wetted measuring tube and process connections are available in 1.4404 (316/316L) stainless steel, with stainless-steel construction for cryogenic applications.
Space-Saving Installation
Because Promass Q 500 uses the Coriolis measuring principle, conventional inlet and outlet straight pipe runs are not required.
This can simplify piping design and reduce the installation footprint, particularly in compact metering systems and process skids.
Flexible Digital Communication
Promass Q 500 provides flexible communication and I/O options for integration into modern industrial automation systems.
Depending on the selected configuration, communication options support integration with:
PLC
DCS
SCADA
Metering systems
Plant asset management systems
The freely configurable I/O architecture helps adapt the transmitter to different process control and instrumentation requirements.
Heartbeat Technology
The Promass Q 500 incorporates Endress+Hauser Heartbeat Technology for integrated verification and diagnostics.
Heartbeat Technology supports device verification and measurement monitoring, helping users maintain confidence in measurement performance and simplify maintenance planning.
