3.2 Flow sensor position
A Recommended flow sensor posiion.
B Recommended flow sensor posiion.
C Unccepble posiion due o risk of ir
build-up.
D Accepble posiion in closed sysems.
E A flow sensor ough no o be plced
immediely fer  vlve, wih he
excepion of block vlves (bll vlve ype)
which mus be fully open when no used for
blocking.
F A flow sensor mus never be plced on he
