Did you know that the conductivity of water changes geographically? In different parts of the U.S. there is more sedimentary rock (rock formed by erosion) that gets into the public water system and this makes the water more conductive in those areas.
Conductivity and Total Dissolved Solids (TDS) are the same thing measured on different scales. The latter (TDS) measures physical particles in the water and the former (Conductivity) measures those dissolved particles’ ability to conduct electrical energy. In the R & D process, Waterline Controls realized (twenty years ago) that our products needed to work in a wide range of conductivity, so we designed our electronic water level controllers for these conditions accordingly.
There is no conductivity in pure water. Steam is the purest elemental water that can be found. Distilled water is a close second. Then there is Reverse Osmosis and some argue that certain nano-filtration methods rank up near the top.
When pure water is evaporated off and make-up water is added, it increases the conductivity over time. Examples of this include Cooling Tower Water, Swimming Pool Water, Fountain water – virtually any environment that lends itself to even moderate evaporation rates. Obviously, the evaporation rates are different in all of these different situations, but the principle is the same, resulting in ever-changing Cycles of Concentration.
Water conductivity is important to us at Waterline Controls because we are using it to complete an electronic circuit. All Waterline Controls units work in very low conductivity environments. All of our water level controllers are Electronic, not electric, and that makes a huge difference in the performance of our products at different conductivity levels.
So when you are out there on a project and wondering if Waterline Controls will work in a low TDS situation, the answer is – YES IT WILL. If you have any concerns about an application, call me directly at (888) 905-1892 and I can let you know before you purchase. We want you to be 100% Satisfied.
