VORTEX offered complete engineering services to Cobra. Our task was to find a solution to long-term standing problem of measuring turbidity in incoming potable water. VORTEX found a reason for impossibility of measuring turbidity, designed custom engineering solution, installed and successfully commissioned the system. The system works fully in automatic mode, measures turbidity of water with at least 95 per cent precision, and automatically controls condition of the sensor, using Prognosys maintenance module installed. Based on the value of turbidity of water, using sensor Solitax SC, paired with SC1000 Controller by Hach, water pressurization / filtration plant is altering modes of operation, from filtering of water if turbidity level is satisfactory, or discharging highly turbid water into a river.
