Flow Calibration

The E+E accredited calibration bench is unique in Europe and offers flow and volumetric flow calibrations for inline and immersion flow meters at standard conditions in the range from 0.6 to 2300 m³/h (0.35 to 1354 SCFM) in pipes from DN15 to DN80 (1/2 to 3“). The pressure in the calibration bench can be set between 1 and 10 bar (14.5 and 145 psi), which allows for highly accurate calibration under the real conditions in compressed air networks.

The E+E calibration laboratory operates also an accredited low flow calibration bench in the range from 0.06 l/min to 245 l/min at standard conditions. Calibrations can be performed in pipes from DN15 to DN50, at pressures between 1 and 10 bar (14.5 and 145 psi) and for air and non-air gases.
