Endress+Hauser Proline Promass G 100 Coriolis Flowmeter

The Endress+Hauser Proline Promass G 100 is a compact Coriolis flowmeter designed for accurate measurement of liquids and gases in high-pressure applications. Its combination of a high-pressure sensor and an ultra-compact transmitter provides full measurement functionality while minimizing the footprint of the measuring point. 

Promass G 100 is particularly suited to system integrators, skid builders and equipment manufacturers where installation space is limited but reliable high-pressure flow measurement is required. The Coriolis measuring principle provides direct mass flow measurement and is largely independent of fluid properties such as viscosity and density. 

High-Pressure Liquid and Gas Measurement

The Promass G 100 is specifically designed for high-pressure process applications, with a maximum process pressure of 350 bar (5080 psi).

It provides measurement of:

• 
  Mass flow
  
• 
  Volume flow
  
• 
  Corrected volume flow
  
• 
  Density
  
• 
  Reference density
  
• 
  Temperature
  

The instrument can therefore provide multiple process variables from a single measuring point, helping reduce the number of separate instruments required in compact process systems. 

Accurate Measurement Performance

Promass G 100 provides reliable measurement of both liquids and gases:

• 
  Liquid mass flow: ±0.15%
  
• 
  Liquid volume flow: ±0.15%
  
• 
  Gas mass flow: ±0.75%
  
• 
  Liquid density: ±0.0005 g/cm³ 
  

This makes the flowmeter suitable for applications where accurate flow measurement must be maintained under high-pressure operating conditions.

Compact High-Pressure Sensor

A major advantage of Promass G 100 is its compact high-pressure sensor design.

The flowmeter is available in nominal diameters from DN8 to DN25 (⅜ to 1"), with a measuring range of up to 18,000 kg/h (662 lb/min). 

The measuring tube is manufactured from 1.4435 (316L) stainless steel, while the process connection is 1.4404 (316/316L). 

Threaded Process Connections

Promass G 100 uses internal threaded process connections, providing straightforward and secure integration into suitable high-pressure piping systems.

A rupture disc is also available as an option, providing an additional safety feature for high-pressure process applications. 

Ultra-Compact Transmitter

The Promass G 100 incorporates an ultra-compact transmitter housing, providing full functionality within a very small footprint.

This space-saving design is particularly valuable for:

• 
  Skid-mounted systems
  
• 
  Equipment packages
  
• 
  System integration
  
• 
  Compact process installations
  
• 
  OEM equipment
  
• 
  Applications with restricted installation space
  

The transmitter also includes an integrated web server, allowing configuration through a web browser without requiring additional operating hardware or software. 

Flexible Communication

Promass G 100 supports several communication options for integration with industrial 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 Promass G 100 to be integrated into PLC, DCS, SCADA and industrial automation systems.

Wide Process Temperature Range

The flowmeter is designed for process temperatures from:

-50 to +150 °C (-58 to +302 °F). 

Combined with the maximum process pressure of 350 bar, this makes Promass G 100 suitable for demanding high-pressure liquid and gas measurement applications.

Space-Saving Installation

The Coriolis measuring principle allows Promass G 100 to be installed without conventional inlet and outlet straight pipe runs.

This can simplify piping design and reduce the overall space required around the flow measurement point, which is particularly useful for compact skids and packaged equipment. 

Heartbeat Technology

Promass G 100 incorporates Endress+Hauser Heartbeat Technology for integrated verification and diagnostics.

Heartbeat Technology helps users verify instrument performance and supports measurement traceability without requiring the flowmeter to be removed from the process. The product page also notes calibration on accredited facilities according to ISO/IEC 17025. 
