Yoko­gawa Elec­tric Cor­po­ra­tion has expand­ed its range of ana­lyz­ers in the OpreXTM prod­uct fam­i­ly for water treat­ment plants. With the launch of the new prod­ucts, the water treat­ment tech­nolo­gies that already pro­vide high-qual­i­ty drink­ing water in Japan will now be avail­able in South­east Asia, the Mid­dle East, South Korea, Aus­tralia and Tai­wan. From April 2021, they will be suc­ces­sive­ly launched in North and South Amer­i­ca, Europe and China.

Development background

Water qual­i­ty needs to be con­tin­u­ous­ly mon­i­tored, and when defi­cien­cies occur, a rapid response is required to ensure a safe drink­ing water sup­ply. Accord­ing to World Health Orga­ni­za­tion (WHO) guide­lines, tur­bid­i­ty and chlo­rine lev­els must be test­ed in all drink­ing water supplies.
Since the launch of the free chlo­rine ana­lyz­er (reagent-free mea­sure­ment) in 1962 and the tur­bid­i­ty trans­mit­ter in 1973, Yoko­gawa has been a world leader in tur­bid­i­ty and chlo­rine ana­lyz­ers and has con­tin­u­ous­ly devel­oped these prod­ucts to meet the strin­gent require­ments of Japan­ese water sup­plies. These prod­ucts fea­ture self-diag­nos­tic func­tions that opti­mize the main­te­nance of process plants and equipment.

Features

Yoko­gawa’s ana­lyz­ers use trans­mit­ted light and scat­tered light mea­sure­ment meth­ods, which are rec­og­nized as the de fac­to stan­dard by water util­i­ties in Japan and are char­ac­ter­ized by their high reli­a­bil­i­ty. Self-diag­nos­tic func­tions that reli­ably indi­cate when main­te­nance is due and when faults have occurred are pro­vid­ed by both the TB820D tur­bid­i­ty detec­tor and the FC800D and RC800D ana­lyz­ers. The RC800D also reports when no mea­sur­ing liq­uid is present.
In addi­tion, oth­er SENCOM 4.0 sen­sors can be con­nect­ed to the FLXA402T liq­uid ana­lyz­er for tur­bid­i­ty and chlo­rine mea­sure­ments (pH, con­duc­tiv­i­ty). The val­ues deter­mined can be trans­mit­ted wire­less­ly to a cloud so that they can be mon­i­tored from any loca­tion. This min­i­mizes the need for on-site oper­a­tion and main­te­nance and ensures more effi­cient oper­a­tion of plants whose devices are dis­trib­uted over a large area.

Lower implementation costs by connecting multiple sensors

Unlike sim­i­lar prod­ucts cur­rent­ly avail­able on the glob­al mar­ket, the prod­uct can be oper­at­ed simul­ta­ne­ous­ly with two tur­bid­i­ty detec­tors and chlo­rine sen­sors. This sig­nif­i­cant­ly reduces imple­men­ta­tion costs at sites that require the use of mul­ti­ple sensors.
