Vision

EuroLoop activities:• Calibration, verification and type testing of

industrial flow meters (gas and liquid)• Large scale experimental position for R&D on

Gas and Hydrocarbon flow• Mid and high level Training in Metrology and

Oil & Gas

EuroLoop will consist of:• HyCal: Circuit for industrial liquid flow meters


HyCal: Circuit for industrial liquid flow meters• GasCal: Circuit for industrial gas flow meters• Building with control room, training centre and

offices• On just 200*100 m near Rotterdam (NL)

Operated by NMi

• NMi is independent and autonomous operator of all facilitiesp

• Equal treatment for every customer (price, passage period, etc.)

• Third party access upon permission only, dependent of ongoing

What is EuroLoop? (1 of 2)

GasCal (test loop for Gas):

• Flow (working) 5 – 30.000 m3/h(normal) 5 1 800 000 m3/h

YEAR-

+ constant Gas composition -> low Umass

(normal) 5 – 1.800.000 m3/h• Meter sizes 2” – 30” • Pressure 1- 65 Bar• Uncertainty better than 0.20% (0.10%)• Measuring streets 5• Master meters 16• Gas temperature from about 5 … 10 ºC

T bili b h 0 05 ºC

ROUND!


• Temperature stability better than 0.05 ºC• Pressure (system) stability better than 5 mbar• No. of test runs 5 (2 simultaneous)• Capacity 800 – 1500 meters/year

Unique In the World!

Features HyCal overview

• Primary traceability from Length

Experience from (our) existing facilities brought into practise :

• Primary traceability from Length• Continuous primary calibration• Online leak detection• Online stability monitoring of the moving

piston• Temperature and vapour sensing based on

speed of sound


speed of sound• Line pack monitoring through extensive

temperature and expansion-flow metering • Accurate + fail safe control of piston

departure and deceleration
