Description
The AquaLogger Compact is a remote water and wastewater level station with a Radar or Hydrostatic sensor. The logging device and battery supply are both enclosed in a 220 x 120 x 90mm housing.
Such configuration allows Aqua Logger RDR COMPACT to be suitable for level monitoring in closed channels, sewage wells, small scale sewage pumping stations and similar locations where compact size of a device is important. There are three protection levels available: IP67, IP68 and IP67 ATEX.
The station is powered by a set of Lithium batteries placed inside the housing. With a measurement taken every 10 minutes and the data transmission made every 4hours, the station is able to operate for 5 years minimum.
Twelve months online datahosting and access is included initially.
