IV. System Composition

The microsystem for water quality monitoring in the supply is composed of a power 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

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.
