The Requirement

The River Adur, located in Sussex is 20 miles long and approximately 400 square kilometres. Long term remote monitoring is required to understand which sub catchments produces the most water into the main river. There are 19-sub catchments to the river, so understanding which locations need to be monitored is crucial to the project. Due to the locations and access of the sites, telemetry is essential. The project expects to progress for the next 5-10 years.

The Solution

It was decided that the most valuable data for this project would be the monitoring of water flow. Five locations were chosen, and a site visit was crucial to determine which flow solution would be viable for each site. After the site visit, it was concluded that we would install ultrasonic flow meters with our telemetry system for three of the locations, but due to poor access conditions we decided to postpone installing equipment of the other two sites.

For each of the three sites, an ultrasonic flow meter was installed with its own DataHub and solar panel. Due to the location of two of the sites, fencing was installed to prevent any potential damage from curious cattle. All three sites will have quarterly visits from our team to verify data using our portable NivuFlow Probe stick.
