Mount a sitch, so that th liuid flo is in th sam dirction as that of th arro on th body.. B sur to fill th passag ith th fluid.. Th flo sitch can b installd ithr horizontally or vrtically. 4. Provid a straight pip portion that corrsponds to approximatly 5 tims th bor of th pip bfor and aftr th ara of th pip on hich th product is installd, thus kping th product as far aay as possibl from th lmnts that disturb th flo, such as lbos or valvs. 5. For iring, rfr to th intrnal iring diagram. 6. If a trminal box is not availabl, ir by slcting th contact at a or b. t that tim, insulat th s that ill not b usd. 7. Bcaus this is an opn styl, it cannot b usd hr atr or oil splashs. 8. It cannot b usd if a atr hammr or pulsation prssur is applid to th fluid. 9. In ordr to prvnt a malfunction or diaphragm damag causd by dbris or cutting chips in th fluid, install a filtr ith approximatly 00 msh on th inlt sid of a flo sitch. djusting. To adjust flo, rmov grommt of th uppr covr and rotat flo adjusting gar using a flat had scrdrivr. Turning clockis can incras th st flo and turning countrclock can dcras th st flo.. Th flo rat stting point is st at th ON flo rat. Thrfor, in th cas of th a contact, th ON signal is output if fluid ith a highr flo rat than th st flo rat has occurrd. In th cas of th b contact, th ON signal is output hn th flo rat has dcrasd from th st flo rat for th amount that corrsponds to th hystrsis.. To prvnt th chattring that is associatd ith th fluctuation of th oprating flo rat, st th diffrnc btn th st flo rat and th oprating flo rat so that it is as larg as possibl. 4. Us at or blo th maximum oprating prssur and maximum flo rat. 5. Th indicator on th indo nam plat (Fig. ) is only a guidlin. For prcis stting, mount a flo mtr on th donstram sid of th flo sitch, and st th lvl. lso, hn stting lvls ith a lo flo rat at prssurs of 0.

In such cass, dtach th indicator ndl and scal plat bfor stting. ftr stting, th indicator ndl and scal plat can b rattachd in positions of your choic.
