It is important that the ILVA20 is located centrally in the pipework as any eccentricity may cause inaccurate
readings. The ILVA20 has been designed with integral centering webs which locate on the internal diameter
of the pipework.
Note: The ILVA20 is calibrated using schedule 40 pipework at the factory.
If the ILVA20 is installed into a system using other schedule pipework (including schedule 80) the calibration
will be affected.

4.3 Location in pipework
Bolt ring gaskets having the same internal diameter of the pipework are recommended. This will prevent
possible inaccuracies being created by the gasket protruding into the pipe.
