Measuring station
The measuring station with Compac welding neck flanges is used to
precision-mount the electronic volume flow sensor. The measuring
station is welded into pipelines with the Compac welding neck flanges
in line with the direction of flow (see engraved direction arrow). The
nominal width of the measuring station and welding neck flanges
must match the nominal pipe width (
seam during welding, the material of the parts must also be the same.
The compressed air meter is designed for nominal pipe widths from
DN 65 to DN 250.

ISO calibration certificate
The compressed air meter is supplied calibrated to its nominal width.
A minimum of six measuring points are parametrised with specified
nominal widths, standard temperatures and pressures, then moved to
the test stand where the standard volume is tested. The calibration
certificate is included in the delivery.
