2.4.5 Gaskets
Use only the gaskets supplied with the instrument. The gaskets supplied with the meter are the
proper size for the meter size and type specified. When installing the meter it is important that the
correct size gaskets be utilized. Use of the wrong size gaskets could allow the inner diameter of the
gasket to protrude into the flow stream, thereby altering the flow profile within the meter. This
condition could affect meter accuracy significantly and must be avoided. Using the proper gaskets
and installing them correctly will also avoid any possibility of leakage. Observe parts information
given in Section 6.0. Refer to Figure 2-19 for proper gasket locations.
Do not use graphite gaskets. Under certain conditions they
may cause an electrically conductive layer to form on the in-
side wall of the meter, causing meter operation to degrade.
