3. Measuring principle
This module monitors by Constant incident light Irradiated
on liquid surface，The receiving chip will dynamically measure
the chroma of water 。If the water is turbid, it may affect the
measurement accuracy ，It is recommended to filter and clean
before entering water。
4. Structural features
Outline structure and installation instructions of Online Color Meter，
As shown in the figure below。
Careful：
1. Outflow valve flow control to minimum，
It must be
less than the inflow flow ，Let the measuring tube
have a certain air pressure，Otherwise, there will be
bubbles，Influence measurement value
2. Panels should be installed vertically

5. Installation wiring
6．1．Instrument installation
The instrument shall be installed in a clean, dry, well
ventilated place without vibration。
1．There are 4 studs on the bottom plate for installation。
2．Interface between measurement and water sample
collection 1/4" NPT Internal thread ，You can also choose card
sleeve installation.。
Influent mode：
Down in and up out，
Keep the inflow
valve as small as possible，The best way is that water
does not produce bubbles。
