Model WA-1 Hydroinfo Monitor Station

 
1Application
Model WA-1 Hydroinfo Monitor Station is a device which is able to automatically collect the measured data from hydrometeorology transducers. It can be widely used for water, electricity, railway, road, mine, national defense, civil engineering and so on situations.
Transducers that Model WA-1 Hydroinfo Monitor Station can collect data from are either: Water Level meter, Rainfall Sensor, Weir Transducer and so on hydrology transducers; or: Air Pressure Gauge, Temperature Gauge, Wind Speed, Wind Direction transducers and so on meteorology transducers.
The main functions are: automatic collecting of measuring data, offline collecting, real-time online collecting, auto reporting with preset time, auto reporting about rainfall amount, auto reporting about water level, battery voltage monitoring, power charging with solar energy, RS232/RS485 communication, big capacity memory, etc. Either GPRS or wireless data transceiver can be selected as wireless communication module.
Model WA-1 Hydroinfo Monitor Station has a compact structure. Also it has a full stainless steel outer box that can avoid stealing and also looks nice. It can easily be installed also it can against rain and dust very well.
