Measuring station
3.5
The measuring station with Compac welding neck flanges is used to
precision-mount the electronic volume flow sensor. The measuring station
is welded into the pipelines with the Compac welding neck flanges in line
with the flow direction (see engraved direction arrow). The nominal width
of the measuring station and welding neck flange must match the
nominal pipe width (
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 points
3.6
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
in compliance with ISO/IEC 17025 is included in the scope of delivery.
