Drug concentration monitor

The DP88370 fluorescent tracer uses advanced fluorescent tracer technology to trace the corrosion and scale inhibitor first. After the pesticide is added, when the circulating water flows into the water sample collector through the bypass, the missing reagent is used by the instrument. Monochromatic light is activated, producing fluorescence, and the intensity of the fluorescence is linear with the concentration of the agent. The instrument uses a stable low-power light source, high-precision photoelectric converter, and the light-reflecting reflection to the photoelectric converter generates a weak current. The weak current is amplified by the high-power amplifier and processed by the single-chip microcomputer to output two 4-20mA current signals. : One way 4-20 mA current signal goes to the pull machine, can enter the machine dialogue, realize automatic supervision; another 4-20 mA current signal to control the dosing pump. The instrument can use the PID to output control according to the manually set control value. When the error is large, the fuzzy algorithm is used to adjust to eliminate the PID saturation integral phenomenon;
