possible to determine COD where particles up to a certain size must also be measured.
Mounting materials are not included in the scope of supply and must be provided by the
customer.
Dimensions of Y strainer →  12
Mounting the Y strainer on an even surface
1. Mount the Y strainer on the pipe clamps on an even surface. The Y strainer should be
