TDS: total Dissolved Solids (TDS), also known as Total dissolved solids, is measured in milligrams per liter (mg/L) and indicates how many milligrams of dissolved solids are dissolved in 1 liter of water. Higher TDS values indicate more solutes in the water. TDS test still has certain referential meaning to water quality testing, especially when impurity is too much in the quality of water, TDS can show great numerical value, and simply TDS value is relevant with the clean degree of quality of water. Such as: after the purified water and the mineral water are kept for a long time, the TDS value is too high to start rising, the total number of the common viruses and the bacterial colonies is correspondingly increased, and the health is influenced because the common viruses and the bacterial colonies cannot be drunk at the moment. The measurement principle is actually to indirectly reflect the TDS value by measuring the conductivity of the water.

As shown in fig. 5, the turbidity sensor 101 and the TDS sensor 102 are located above the centrifugal water pump 22.
