Conductivity sensor gets measure of evaporation

The ICT1 inductive conductivity sensor from Prominent Fluid Controls can be used in conjunction with the company's Cool-Control system for fully automatic desalination control in cooling towers.

The ICT1 inductive conductivity sensor from Prominent Fluid Controls can be used in conjunction with the company's Cool-Control system for fully automatic desalination control in cooling towers.

The ICT1 is designed for use in all types of soiled water and has a conductivity measurement range of 0.2-1000mS/cm.

The sensor operates at temperatures up to 70C, with full temperature compensation and the maximum pressure rating is 8bar at 40C and 1bar at 70C.

As water evaporates in the water tower, the ICT1 measures the increasing salt concentration through the increasing conductivity.

When a preset upper level is reached, the Cool-Control system opens a valve and the water drained and fresh make up water introduced until the conductivity drops to a preset lower level.

The Cool-Control system can be used for all water treatment processes involved in cooling towers including inhibitor dosing and biocide metering as well as desalination.

Cool-Control can accept a number of signal inputs and has several output control channels, as well as featuring an integral day/week timer and interlock facilities.

A clear display shows various process parameters.

The unit can also control calibrated pumps for dosing inhibitor using an input signal from, for example, a contact water meter.

Two independent biocide dosing pumps can also be controlled, usually on a timer basis.
