PDS In-Situ Water Quality Monitoring Stations

Introduction

The PDS Water Quality Monitoring Station (WQMS2080) is designed to provide organisations with an automatic means of continuously monitoring the water quality of ponds, streams, sewers, drains and watercourses etc. Liquid trade waste effluent being discharged from manufacturing and processing facilities is a concern not only for the environment but can also impact on the production and efficiency of the facility.

The PDS Water Quality Monitoring Station is a stand-alone station with the only cabling need being the cabling to the sensors and to any control equipment being switched by the station. The power for the station and sensors is typically supplied by solar panels and a rechargeable backup battery but can be supplied by other means such as 240VAC mains supply (with standby, battery backup), diesel generator or wind generator.

Communications to the station can be made either by direct connect (Ethernet, USB or RS-232) with a PC or by Wi-Fi radio connection or other modem (GSM, 3G or satellite).

Generally, what is in a Water Quality Monitoring Station?

► Submersible in-situ water quality transmitters for each water quality parameter that is required to be monitored. These are connected to the control unit by cables which may be up to 100 metres long.

► The control unit containing the supervisory module, the data logger, the radio telemetry module and any accessories; all housed in a weatherproof outdoor enclosure.

► Power supply (either solar panel with mounting brackets, mains adaptor or wind generator)

Sensors

Standard monitoring parameters such as:

► pH;

► Electrical Conductivity;

► Dissolved Oxygen,

► ORP (redox);

► Turbidity.

► Temperature.

► Level.

Extended monitoring parameters (but not limited to):

► Ammonium;

► Nitrates;

► Nitrites;

► Suspended solids;

► Chlorine;

► Underwater UV;

► Flow or level.

Flow or level is a popular choice and can be measured by a variety of flowmeters and level sensors, including electromagnetic flowmeters, turbine (impeller) flowmeters, area / velocity and Doppler / ultrasonic / radar flowmeters.
