Is a metering pump dosing device (such as GM0120PQ1MNN) as the main feeding equipment, dissolving kit, stirrer, level gauge, safety valve, check valve, pressure gauge, filter, buffer, piping, valves, base, escalators, automatic monitoring system, power control system is assembled in a public platform according to the process the process need to form a module, called skid mounted modular units ("skid"). According to the quantitative reagent box into the mixing solution dissolved after stirring to dissolve again through the work process to the metering pump dosing, the dosage of the size can be freely adjusted to meet different dosage place.

1. the dosing and corrosion inhibitor adding unit of the dosing device automatically controls the dosage according to the supplementary water flow which is supplied by the water flow sensor. Under the premise of guaranteeing the effect, the dosage of the medicament is reduced to the maximum extent.

2. the dosing unit of the dosing device controls the frequency of the impact and continuously inhibits the breeding of bacteria and algae through time.

3. acid adding unit of dosing device is generally selected for high alkalinity and high hardness water supply system, and pH sensor is used to precisely control the dosage of acid and neutralize the alkalinity of water supplement.

4. the unit of dosing device monitors the conductivity of the water in real time, and controls the discharge of the electric valve to avoid blind drainage and waste water resources according to the setting concentration factor.
