Endress+Hauser Proline Prosonic Flow G 500 Ultrasonic Flowmeter
The Endress+Hauser Proline Prosonic Flow G 500 is a robust gas ultrasonic flowmeter designed for accurate and reliable measurement of natural gas and process gas in demanding industrial applications. It is particularly suitable for the oil & gas and chemical industries, where gas composition and process conditions can fluctuate significantly.
The Prosonic Flow G 500 uses an ultrasonic time-of-flight measuring principle and is available as a remote transmitter version with up to 4 configurable I/Os, providing flexible installation and integration into process control systems.
Ultrasonic Gas Flow Measurement
Prosonic Flow G 500 is designed specifically for gas applications and provides reliable measurement over a wide gas velocity range.
The measuring range is:
0.3 to 40 m/s
Standard volume flow accuracy is:
±1.0% o.r. for 3 to 40 m/s
±2.0% o.r. for 0.3 to 3 m/s
With optional calibration, accuracy can be improved to:
±0.5% o.r. for 3 to 40 m/s
±1.0% o.r. for 0.3 to 3 m/s
This wide measuring range allows the flowmeter to handle changing gas flow conditions in industrial process systems.
Natural Gas and Process Gas Measurement
The Prosonic Flow G 500 is particularly suited to natural gas and process gas measurement.
Typical applications include:
Natural gas measurement
Process gas measurement
Fuel gas measurement
Gas distribution
Oil & gas production
Oil & gas processing
Chemical plants
Industrial gas systems
Gas process monitoring
Its robust design makes it suitable for applications where reliable gas measurement is required under changing process conditions.
Reliable Measurement Under Fluctuating Conditions
A major advantage of the Prosonic Flow G 500 is its ability to operate under fluctuating process conditions.
The instrument provides stable ultrasonic gas measurement while accommodating changes in gas velocity and process conditions, making it suitable for demanding industrial gas applications.
The flowmeter can provide both volume flow and corrected volume flow, supporting applications where gas volume needs to be referenced to defined operating conditions.
Corrected Volume Flow Measurement
In addition to standard volume flow, Prosonic Flow G 500 supports corrected volume flow measurement.
Standard corrected volume flow accuracy is:
±1.2% o.r. for 3 to 40 m/s
±2.1% o.r. for 0.3 to 3 m/s
With optional calibration:
±0.8% o.r. for 3 to 40 m/s
±1.2% o.r. for 0.3 to 3 m/s
This functionality is useful for gas applications where measured flow needs to be compensated for process conditions.
Wide Process Temperature Range
Prosonic Flow G 500 supports a medium temperature range of:
-50 to +150 °C
When an integrated pressure cell is used, the medium temperature range is:
-50 to +100 °C.
This wide temperature capability allows the instrument to operate in a variety of demanding gas measurement environments.
High Process Pressure Capability
The flowmeter supports process pressures from:
0.7 to 101 bar a
providing a broad pressure range for natural gas and process gas applications.
This makes Prosonic Flow G 500 suitable for both relatively low-pressure gas systems and higher-pressure industrial process installations.
Remote Transmitter Design
The remote transmitter configuration allows the sensor and transmitter to be installed separately.
The transmitter supports:
Up to 4 configurable I/Os
Flexible signal configuration
Local process information
Diagnostic information
Convenient transmitter access
Flexible installation
Separating the sensor from the transmitter can be particularly useful when the measurement point is located in a difficult-to-access area or when the transmitter needs to be installed at a more convenient location.
Robust Gas Measurement Construction
The Prosonic Flow G 500 is designed for demanding industrial environments.
The measuring tube is manufactured from:
1.4408 / 1.4409 (CF3M)
while the transducer uses:
1.4404 (316/316L) or Titanium Grade 2, depending on configuration.
This robust construction supports reliable long-term operation in oil & gas and chemical process environments.
Industrial Communication and Integration
The Prosonic Flow G 500 is designed for integration into modern process automation systems.
Its configurable I/O architecture supports integration with:
PLC systems
DCS systems
SCADA systems
Oil & gas control systems
Chemical process control systems
Gas measurement systems
This makes the flowmeter suitable for both standalone gas measurement and larger automated process systems.
Ultrasonic Time-of-Flight Technology
The Prosonic Flow G 500 operates using ultrasonic time-of-flight technology.
The ultrasonic measuring principle determines gas flow velocity based on the difference in ultrasonic transit time through the flowing gas. This provides a non-mechanical measurement method without moving parts, supporting reliable operation and reduced mechanical wear.
Heartbeat Technology
The Prosonic Flow G 500 incorporates Endress+Hauser Heartbeat Technology for device verification and diagnostics.
This supports measurement verification and provides additional information about instrument condition, helping operators maintain reliable gas measurement and plan maintenance more effectively.
