IV. System Composition
The microsystem for water quality monitoring in the supply is composed of a power supply unit, a sensor data monitoring unit, a display unit, a flow cell unit, a remote communication unit, and an integrated box main unit.
1、Power supply unit
Power adapter AC220 to DC12V/2A.
2、Analysis test unit
Analysis test unit, mainly by residual chlorine, PH, water temperature, turbidity, conductivity sensor, through the thread or tight fixing parts fixed on the flow cell, the main parameters of the sensor are as follows
| Serial number | Sensor type | Measurement range | Measurement principle | Measurement accuracy |
| 1 | Residual chlorine | 0~5.00 mg/L | Electrode method | Reading ±5%; ±0.3℃ |
| 2 | pH | 0~14 (ph) | Electrochemistry (salt bridge) | ± 0.1PH |
| 3 | Water temperature | 0~50℃ | High-precision digital sensor | ±0.3℃ |
| 4 | Turbidity | 0~40NTU (optional) | Scattering light method | ± 1% |
| 5 | Electrical conductivity | 0~5000uS/cm | Contact method of electrode | ± 1.5% |
Note: The sensor must not be installed upside down or horizontally, it must be installed at an angle of at least 15 degrees.
The above water quality sensor works in the environment of 0-50℃, <0.3Mpa.
Monitoring parameters can be configured with corresponding sensors according to demand, and only some sensor parameters are listed above for reference. For details, please read the sensor manual.
