Van Walt is delighted to add the new YSI ProQuatro to its fleet of Water Quality equipment. The ProQuatro is a tough, smart and versatile handheld instrument to replace the ProPlus, and is one of several options we offer to monitor water quality parameters.Find out more ....
The Requirement: To monitor the groundwater and water level in and around a landfill site.
Solution: Deployment of a vanwaltDataHub connected to Keller sensors to provide information every 15 minutes which is then uploaded hourly and alarm notifications sent directly to the site managers for immediate action to ensure the facility is running effectively.
The Requirement: Flow rate of streams determine water abstraction permissions to the ski field operator who requires water for snow making. The regulator requires daily data.
Solution: Flumes are installed to derive water flow data. Using the alarms functionality a water pump is either switched on or off. Data is automatically forwarded to the regulator by FTP. A similar system is also used to switch off the pumps when the turbidity is too high and could damage the pumps.
The Requirement: Large sluice gates between lake and river affect the level of the adjacent river when they are opened. The regulator wishes to establish the effect.
Solution: Installation to record data every 5 seconds with an accuracy better than 5mm. Uploads every 30 minutes to our server and daily transfer of data by FTP to the regulator.
The Requirement: A research project monitoring the soil moisture on a small, uninhabited island in the Atlantic, just off the coast of Spain where the cost and difficulty of getting to the island was far in excess of installing a system that could relay the data back to the mainland without having to go to site.
Solution: Deployment of multiple, buried Soil Moisture probes - HydraProbes - connected to a single vanwaltDataHub. The batteries in the DataHub topped up with a solar panel and the installation protected with a perimeter fence. Data is collected hourly and uploaded once a day for analysis.
The Requirement: Whatever your requirment, when it comes to an extra pair of hands to help install equipment or complete an entire installation, the team in the New Zealand Office can help.
Solution: Window Sampling; Piezometer Installation; Lake & River Bed Sediment Sampling; Pump & Slug Testing; Soil Permeability & Moisture Testing and Data Logging & Telemetry Equipment
The Requirement: Part of the infrastructure is below the water level and could be subject to flooding. Dewatering pumps on the adjacent properties exacerbates the problem.
Solution: A number of Van Walt Data Collection Systems monitor the water levels. Alarms have been set so all parties receive an early warning that flooding could occur.
Madagascar is endowed with an extraordinary bounty of natural resources, but is subject to widespread environmental destruction. Read how the Tropical Biology Association (TBA) has set up courses to restore environmental habitats.
We have developed a versatile, secure, flexible, sophisticated and accurate web-based groundwater; water level; water quality and soil moisture telemetry system...
