Hydrological and wastewater systems

Ecowise Instrument group offers solutions to monitor various water parameters, for business and industry. All continuous water level/quality monitoring systems are based on the use of quality instrumentation with a proven track record. Ecowise systems are for unattended, long term, continuous monitoring of environmental data. Our systems are of the highest quality and are versatile and reliable for use in the harshest environments.

Major design elements:

  • The dataloggers is chosen on number of channels, number of sensors and communication method required.
  • Power supplies are selected to suit the location and application. Solar, mains or micro-hydro powered (or a combination) stations can be supplied.
  • Mathematical calculations can be programmed into the datalogger to provide continuous information on derived parameters (e.g. stream flow or dam volume).
  • Data recording (logging) rate is programmed to suit the site characteristics and client requirements.
  • The capacity to upgrade and expand the systems is virtually endless. Sensors can be added to sites and new sites can be added to networks. Simple rainfall or level monitoring stations can be reconfigured into full water quality stations.

Systems that can be supplied include:

  • water level, velocity, pressure and flow
  • water temperature and quality
  • automatic and refrigerated samplers
  • water quality monitoring trailers and buoys
  • sewer (including gas monitoring) and trade waste.

All stations are self contained. The logger/telemetry equipment is usually packaged within a sealed enclosure for protection again the environment. This may then be secured within a second enclosure or hut to provide further protection and to permit the storage of sensor cables.

The station sensors are normally secured in the water within individual galvanised steel, stainless steel or PVC mounting fixtures. These fixtures can be mounted vertical against a solid surface/post or down the stream/river bank (depending upon the sensor requirements). The sensor cables may be bought into the enclosure/hut directly or via a junction box (in the case of long cable runs). The junction box permits ease of access for sensor cleaning and maintenance purposes.

All stations are designed to be as low powered as possible. Sites may be powered using solar panels, 240VAC, wind turbines or micro-hydros (or a combination of these). In all cases a sealed lead acid (SLA) battery will be installed to ensure 100 per cent station operation and data recovery.
