Van Walt is delighted to add the new YSI ProQuatro to its fleet of best-in-class environmental research equipment. The ProQuatro is a tough, smart and versatile instrument to replace the ProPlus.Find out more ....
The Requirement: : Within the Smart Bog Project a need to identify water flow was identified with collected data imported into a model to assess water flow alongside other environmental parameters.
Solution: Deployment of flumes with high accuracy water level sensors connected to a vanwaltDataHub. Different monitoring points networked using vanwaltDataSlaves.
The Requirement: : To report on a range of environmental parameters including water level, water flow, rainfall and water quality to ensure compliance with the regulator.
Solution: Deployment of an extensive telemetry network comprising of different sensors attached to a variety of vanwaltDataSlaves talking to strategically placed vanwaltDataHubs to ensure complete coverage of a large geographical area, in a cost effective and efficient way. Data is uploaded regularly and used to monitor the switching of additional equipment at the site, as well as ensuring compliance with the regulator.
The Requirement: To monitor the groundwater level and temperature over a large area in the most cost-effective way, with data collected every 15 minutes and uploaded hourly for a 24/7 analysis of changes over time.
Solution: Deployment of a telemetry network comprising of accurate water level & temperature sensors attached to vanwaltDataSlaves, some with their antennae raised to ensure a good radio signal. Each DataSlave talks to a single, strategically placed vanwaltDataHub which collates the data from each monitoring point and reports the results from each sensor for analysis, so the findings can be compared across the entire site.
The Requirement: To monitor the groundwater levels in an exposed, remote location with data collected every 15 minutes and uploaded hourly.
Solution: Deployment of vanwaltDataHub connected to an accurate Water Level Sensor. The battery power of the DataHub topped up with a solar panel to ensure continuation of data throughout the project.
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 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: 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.
Madagascar is well over double the size of the UK and has a population of approximately 27 million people. It 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 a range of Rental Equipment; from Groundwater Pumps; YSI Handheld Water Quality Meters to Sediment Samplers. Renting is cost effective and convenient.
We have developed a versatile, secure, flexible, sophisticated and accurate web-based groundwater; water level; water quality and soil moisture telemetry system...
From a Peat Probe, to an Auger Set (or Single Auger or Soil Gouge) to a mechanical Window Sampling System, Van Walt has one of the most comprehensive selections of Soil & Sediment Sampling equipment available.
Accurate and consistent Soil Moisture monitoring has become increasingly important when researching environmental factors like climate change, decreasing water resources, improved crop production and protecting threatened habitats.
Starting out on my internship with the Tropical Biology Association (TBA), supported by Van Walt, I knew very little about Madagascar. However, right from the beginning of my research it…View Post
