We custom build a wide range of telemetry buoys for inland water quality monitoring. These can be used on reservoirs, lakes, rives, tailing ponds, fisheries and inland waterways such as canals.
The buoys can be built with a variety of sensors and operate from either batteries and or solar. Sensors include PH, Turbidity, Salinity, Conductivity, Pressure, Dissolved Oxygen, etc.
Data communications from the buoys is over a wide range of media which includes, low power radio, PMR radio and cellular, such as SMS, CSD and GPRS, MPT1411, EN 300 220, EN 300 113 etc. At the receiving end of the link, data can even be re-constituted as 4-20mA, 0-2V, etc for use with data loggers, programmable logic controllers and via the internet.
