Meter Installation

I want to install a water meter serving a water treatment plant on the abstraction line. The pumps at the abstraction are submersible.

Recently have had issues with meter clogging in other old abstraction points. So this time round, and since this is a new facility, I want to include a strainer before the meter and a non-return after the meter of the same size as the delivery pipe.

Also would like to adopt the above-ground setup. Would this bring any effect on discharge to the plant?
