) for flow meters of DN32 (with straight sections DN 32) is
shown on the plot (see fig. 9.5). The curve 2 demonstrates pressure loss directly on the flow
meter of DN32. The curve 1 demonstrates pressure loss on the flow meter, straight sections
and conical 10°- contractions, while installing the flow meter of DN32 on the pipe of DN 50.
