The adjacent pipes must be parallel and fit the meter.
Meter couplings must be tightened with maximum the torque mentioned in the table below:

30 Nm
Skewness of pipes often makes it difficult to obtain a watertight connection, if the above torques must be
observed, and it can also be difficult to estimate the mounting time in advance.
In such cases, Kamstrup A/S recommends to install the meter by means of a special coupling with
telescopic function. The coupling can be displaced up to 17 mm – to be able to compensate for differences
and inaccuracies of pipe installations, both in the longitudinal direction and, to lesser extent, also against
oblique’ angles. Kamstrup A/S supplies such couplings.
