TDS Screen

The TDS MENU is used to control the concentration of dissolved solids by measuring the conductivity of the water.

The data can be displayed either in conductivity units (microsiemens/cm) or in ppm of Total Dissolved Solids (TDS), using an operator-selectable conversion factor.

The TDS MENU includes selection of:

The TDS MENU is used to set automatic replacemet (dumping or bleeding) of water when the TDS level becomes too high, selecting a control setpoint to activate the dump valve. Backfilling of water is done simultaneously with a level control activated valve.

Up to three different types of chemical additives - such as inhibitor and biocides for cooling towers - can be programmed separately for automatic addition as a function of time, bleed activation, pH control activation or cumulative flow rate.
