We have added additional sensors for water, groundwater & soil parameters, all compatible with our unique, flexible & innovative Data Collection Telemetry systems. Telemetry which works across a range of different sensor types and brands.Find out more ….
The Requirement: Prior to the start of construction monitoring of water quality to assess the impact of turbidity on a nearby water supply.
Solution: Deployment of a vanwaltDataHub and vanwaltDataSlaves, attached to single parameter water quality sensors to monitor turbidity levels with data collected every 15 minutes and uploaded hourly, directly to the regulator and other interested parties.
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.
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: When work began on a brownfield site up for redevelopment the contractors discovered more than they bargained for – Roman remains. Part of our heritage that now needs protecting.
Solution: Deployment of Keller Water Level Sensors attached to a series of vanwaltDataSlaves capturing and storing vital water level data every 15 minutes and relaying it to a vanwaltDataHub, which uploads the data to a server once an hour. This Data Collection system will ensure any relics are preserved for generations to come.
The Requirement: Even on the third floor of a building soil moisture in a heavy clay layer under a patio was causing problems with internal plasterboard walls. To make installation difficult the trial pit was very small, there was a poor mobile signal because the site was surrounded by high walls and heavy IT restrictions were imposed throughout the building.
Solution: We installed a HydraProbe Soil Moisture sensor attached to a vanwaltDataSlave and provided training to the building team on how to download data and replace batteries. Soil moisture readings are collected to the DataSlave and the customer downloads their data at regular intervals to analyze the impact of moisture in the soil, on the fabric of the building.
Enquiries for equipment are like buses, no one enquires about a Flume, then several come at once!
As a result we have put together an article outlining the equipment we recommend for monitoring water flow in rivers and streams.
We have developed a versatile, secure, flexible, sophisticated and accurate web-based groundwater; water level; water quality and soil moisture telemetry system...
