In October 2013 a FlowMark model Mark-III was installed on the 6” diameter PVC riser of a 300 ton evaporative condenser at a medical building in Lake Marry Florida. All chemical treatment was discontinued.
Over the course of 12 months the conductivity bleed set point was gradually increased to attain maximum water savings. Cycles of concentration by chlorides were increased from 4.1 to 14.5 with no new scale forming.
