▶
At a low mass flow rate and a high pressure, make sure
that the installation is tight. The tightness prevents incorrect
measurements or the leakage of the operating fluid.
To make sure that the installation is tight, observe the following
instructions:
▶
Use compression fittings. Mount the compression fittings, in
a way that they are not subject to any stresses.
▶
Use pipes with a diameter that is adapted to the fluid con -
nection of the product, and with a smooth surface.
No inlet section is required.
→
Remove all dirt from the pipes and from the fluid carrying
components of the installation.
→ Cut the pipe squarely [ 1 ] and deburr [ 2 ]. See Fig. 22.
