System and method for operating the same
A system includes a cooler, a concentration meter, a first pump and a second pump. The cooler is configured to cool first liquid by second liquid in the cooler. The concentration meter is configured to measure a concentration of the first liquid. The first pump is configured to move the first liquid according to the concentration. The second pump is coupled to the cooler, disposed with the first pump in a parallel manner, and configured to move the second liquid.

a second terminal of the second valve is coupled to the filter, and
a second terminal of the third valve is coupled to the heater.
7. The method of claim 6 , further comprising:
when the first liquid in the tank is higher than the predetermined temperature, opening the second valve and closing the third valve to flow the first liquid through the second valve into the filter.
8. A method, comprising:
comparing a temperature of first liquid with a predetermined temperature;
when the temperature is lower than or equal to the predetermined temperature, flowing the first liquid through a heater and a valve to a tank;
when the temperature is higher than the predetermined temperature, filtering the first liquid by a filter;
when the temperature is higher than the predetermined temperature, cooling the first liquid by second liquid in a cooler;
when the temperature is not higher than the predetermined temperature, controlling the valve by a pipe coupled between the cooler and the valve;
moving the first liquid according to a concentration of the first liquid by a first pump; and
moving the second liquid by a second pump which is disposed with the first pump in a parallel manner.
9. The method of claim 8 , further comprising:
measuring the concentration by a concentration meter which is disposed adjacent to the second pump.
10. The method of claim 9 , further comprising:
conveying the first liquid by a tube which is coupled to the concentration meter; and
blowing air inside a housing by a fan,
wherein the housing covers the tube and is disposed by a side of the concentration meter.
11. The method of claim 10 , further comprising:
the first liquid flowing into the tube along a first direction and flowing out from the tube along a second direction,
wherein the housing and the fan are arranged along the second direction, and
the first direction and the second direction are approximately perpendicular to each other.
12. The method of claim 8 , further comprising:
conveying air to the cooler for cooling the first liquid.
13. The method of claim 12 , further comprising:
containing the first liquid by the tank;
controlling the valve by the air; and
bypassing the first liquid through the valve into the tank.
