摘要: A chemical blending system includes a mix tank (12) and recirculation line (20) having pump (26) in the for recirculating mixing blended chemical. source of concentrated (28A, 28B) is fluidly coupled to an adding valve (32) located between inlet pump. conductivity-type sensor (34A, 34B) provides continuous measurements concentration. titration analyzer (36) provide periodic concentration measurements. programmable control (40) including processor (42) associated memory (44) (32), analyzer. The executes program controls concentrate as function measurement provided by blend desired
