- Minimizing human resources in measuring parameters.

- Measurements in places with rugged terrain, difficult to access.

- Measurements are updated continuously and instantly.

- Accuracy and science in management and search.

- Best help for executive decision making.

Measuring stations are designed to measure parameters: Water level; gate opening; flow; salinity; turbidity.

Measured parameters are displayed with 2x20 character LCD screen or 7-segment LED display.

The user interface can be selected in Vietnamese or English. The use of interfaces to set up simple parameters.

Data can be transmitted to the center via telephone lines (wired) or radio links.

Automatically time measurement data storage through user settings.

Specifications:

· Dispersion station:

- Connect with sensors measured by 4-20mA current or via RS485 transmission standard.
- Display 2x20 LCD or 7-segment LED.
- Connect to the center via voice or radio waves.
- Store measurement data within 1 month.
- Have backup power within 2 hours, when power grid is lost.
- Measured parameters:

+ Water level: 0-10m, resolution: 5mm, error: ± 0.1%
+ Sliding opening: 0-100%, resolution: 0.1%, error: ± 0.1%
+ Traffic: Calculated based on the above 2 parameters
+ Salinity: 0-1.00%, resolution: 0.01%, error: ± 0.01%
+ Turbidity: 0-800mg / l, resolution: 0.4mg / l, error: ± 0.1%

· Central station:

- Connect with dispersed stations to receive measurement data (automatically or manually).
- Display, store, search saved data.
- Create reports and print.
- Includes: Computers Pentium IV, Windows 9x operating system, modem and software AQUAMON 1.1

Application range:

- Irrigation companies
- At hydroelectric plants (measuring water level and flow).
- Petroleum industry (measuring oil level and flow).
