Endress+Hauser FLOWRUN Fiscal Gas Flow Metering System

The Endress+Hauser FLOWRUN is a modular fiscal gas flow metering system designed for accurate and reliable measurement of natural gas and process gases. It provides a complete metering solution by integrating ultrasonic flowmeters, flow computers, piping, pressure measurement and temperature measurement technology into a configurable metering package. 

FLOWRUN is designed according to industry standards for gas metering runs, making it suitable for applications where measurement accuracy, regulatory compliance and reliable data processing are essential. Depending on project requirements, upstream and downstream piping, instrumentation and flow computing functions can be configured as part of the complete system. 

Modular Fiscal Metering Solution

A major advantage of FLOWRUN is its modular system design. The metering package can be configured according to the required flow rate, pipe size, pressure rating, measurement accuracy and local regulatory requirements.

The system can integrate FLOWSIC600 or FLOWSIC600-XT ultrasonic gas flowmeters together with the Flow-X flow computer, pressure and temperature instrumentation, and the required piping arrangement. This allows the complete metering run to be engineered as a single integrated solution. 

High-Accuracy Natural Gas Measurement

FLOWRUN is designed for applications requiring low measurement uncertainty. With appropriate calibration, the system can achieve a measurement uncertainty of 0.1%. The ultrasonic transit-time difference measurement principle provides accurate gas volume measurement while avoiding mechanical moving parts in the flowmeter. 

The system can measure and calculate key parameters including gas composition, volume, pressure, temperature and flow calculation, providing the measurement data required for fiscal and custody transfer applications. 

Integrated Flow Computer

FLOWRUN can be seamlessly integrated with the Endress+Hauser Flow-X flow computer, which performs the required flow calculations and processes measurement data from the metering system.

The integrated architecture helps simplify system design and provides a coordinated solution for gas volume measurement, pressure and temperature compensation, flow calculation and fiscal data processing. 

Wide Size and Pressure Range

FLOWRUN can be configured for nominal pipe sizes from DN50 to DN1200 and pressure classes from Class 150 to Class 2500. The system supports medium temperatures from -40 °C to +180 °C, depending on the selected configuration and components. 

This broad configuration range allows FLOWRUN to be adapted to different natural gas transmission, distribution, processing and industrial gas metering projects.

Standards and Regulatory Compliance

For fiscal and custody transfer metering, compliance with international standards is essential. FLOWRUN can be supplied in configurations conforming to standards and regulations including:

• 
  OIML R 137-1&2
  
• 
  OIML D 11
  
• 
  ISO 17089-1
  
• 
  AGA Report No. 9
  
• 
  MID 2014/32/EU
  
• 
  PED 2014/68/EU
  
• 
  ASME B16.5 / B16.47
  
• 
  ISO 9001 
  

The exact applicable approvals and standards depend on the selected system configuration and project requirements.

Complete Metering Package

Instead of sourcing each component separately, FLOWRUN provides a coordinated complete gas metering package. Endress+Hauser can take responsibility for the engineering and integration of the metering system, helping reduce project execution effort and simplify procurement.

The system can include:

• 
  FLOWSIC600 / FLOWSIC600-XT ultrasonic flowmeter
  
• 
  Flow-X flow computer
  
• 
  Upstream and downstream piping
  
• 
  Pressure measurement instrumentation
  
• 
  Temperature measurement instrumentation
  
• 
  Gas composition measurement where required
  
• 
  Flow calculation and data processing functions
  

This integrated approach makes FLOWRUN suitable for projects where customers require a ready-to-engineer fiscal gas metering solution rather than an individual flowmeter. 
