The E+E accredited calibration bench is unique in Europe and offers mass flow and volumetric flow calibrations for inline and immersion flow meters at standard conditions in the range from 0.6 to 2300 m³/h in pipes from DN15 to DM80.

The pressure in the calibration bench can be set between 1 and 10 bar , which allows for highly accurate calibration under the real conditions in compressed air networks. 

The flow calibration system permits the calibration of flow meters with a maximum dimension of DN80 to a "volumetric flow rate at standard conditions".

The calibration is carried out as a comparative measurement. The reference and the test piece are arranged in series. Rotary meters are used as a reference to measure the standard volume flow / mass flow as well as the pressure, temperature and humidity.
