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.
If the compression fittings are not delivered with the
product, then choose pipe fittings from another man -
ufacturer. The pipe fittings must be adapted to the
fluid connection of the product. Compression fittings
for G-internal-threaded connections are available as
accessories, see Tab. 30. Also buy the seal for each fluid
