The unique high-pressure calibration facility has the world's largest closed loop and can operate at maximum pressure and flow all year round with utmost environmental caution.

Guaranteed accuracy and broad pressure range

We are accredited to calibrate customer meter lines under operation conditions equivalent to on-site conditions at a pressure range between atmospheric pressure and up to 65 bar g – at maximum environmental caution.

Unique system experienced experts

FORCE Technology specialists provide high-pressure calibration of flow meters at our state-of-the-art facilities in Vejen, Denmark. As an independent partner, we use our competencies within custody transfer flow calibration services and metrology to contribute to positive societal development. The Danish Accreditation Fund DANAK accredits the calibration services we perform.

What's in our high-pressure calibration system?

The high-pressure calibration system consists of:

  • 12” (300 mm) high-pressure closed loop for calibration of gas meters
  • 4” primary twin Piston prover system
  • 24” (600 mm) high-pressure closed loop for calibration of gas meter - the world's largest closed loop

What makes the world's largest closed loop special?

The world's largest closed loop for high-pressure calibration of natural gas meters.
The design ensures calibration at a stable flow, pressure and temperatures of flow meters. 
Blower and heat exchanger at the world's largest closed loop
This construction enables circulation at pressure ranging from atmospheric conditions to 65 bar g.
Length compensator at the world's largest closed loop.
The length compensator ensures that customer meter lines are calibrated under operation conditions equivalent to on-site conditions.
Control monitors at the world's largest closed loop.
Four monitors control the meter (MUT) during the calibration to register differences in the reading between the monitors and the working standards. 
The working standards at the world's largest closed loop.
The parallel working standards make it possible to adjust the calibration conditions to the customer meter.
Gas supply station at the world's largest closed loop.
The closed loop is connected to a transmission pipeline, allowing a fast supply of gaseous flows like air, natural gas, biogas and mixtures with hydrogen within an hour.
Gas discharge station at the world's largest closed loop.
After the calibration, the gas is carefully discharged to the grid, ensuring maximum environmental caution.
