2、 Structure and Wiring
（1） Water Level Ruler Appearance Structure
The water level ruler adopts a stainless steel shell, anti-corrosion naval brass touch points, and anti-corrosion pressure-resistant water-tight potting. The upper end of the water level ruler is connected to the terminal equipment through RS485.
（2） Water Level Ruler Wiring Definition
The cable of the water level ruler is drawn from the upper end of the ruler. The line definition includes power lines and 485 communication lines. The color definition of the wiring is as follows:
No. | Wire Color | define | Note |
1 | Shielded Wire | EARTH | Connected to terminal ground |
2 | Red | +12V | Power supply end |
3 | Black | GND | Reference ground |
4 | White | A | RS485 signal A |
5 | Green | B | RS485 signal B |
3、 Installation
Depending on the application environment, the water level gauge adopts different installation methods:
（1）Flange fixed installation on the ground for roads
（2） U-shaped hoop connector fixed on the wall for dams or places close to the wall
