Control the valve to add water and maintain a stable concentration. What kind of controller can be used to achieve this.
The simplest solution is closed-loop control: a sensor for measuring concentration, along with a PID regulator
Have you heard of the Shuaike online density meter and concentration meter? . . . Have a big meal and eat the dish you choose. . . :Lol 2-second flash density analyzer (portable and benchtop version available, intrinsically safe and explosion-proof; no zero drift, no temperature drift, no time drift – maintains its factory accuracy for life). Portable immersion density analyzer (intrinsically safe and explosion-proof)
There are ones with a strong tone; which brand’s PID controller is good?
