Hydrology

STATION


Aqua Loggers are hydrological stations manufactured by PM Ecology. Their exceptional energy efficiency places them among the best equipment for environmental measurements on the market. Extremely low power consumption allows Aqua Loggers to work much longer in comparison to similar hydro stations currently available. Depending on the chosen data transmission frequency, our stations are able to provide online data from 1 to even 10 years on one battery set. The ultra-low power consumption of each station makes them fully off-grid systems, and in this way lowers the initial cost of installation and maintenance.

POWER EFFICIENCY


Power efficiency is vital in designing water level measurement stations, as it helps conducting long-term measurement campaigns without grid connection in the field and inconvenient maintenance involving charging or replacing batteries. Aqua Logger stations stand out among similar equipment because of its significantly longer operating time on one battery set.

SYSTEM


All measured data is easily accessible through our Online System. Each recording is displayed on multifunctional diagrams and charts. Online System is also used for remote setup of transmission and sampling intervals and alarms. Contact us to get access to demo account.

PM Ecology provides API specification for data transfer to 3 rd party systems and applications. For users interested in direct data transfer to their server, PM Ecology offers open-source collector software free of charge. Get in touch with us for details.

SENSORS


Aqua Loggers work with radar sensors or submersible pressure transmitters. Radar sensors are manufactured by Endress+Hauser (Switzerland). Submersible pressure transmitters are produced by Trafag company (Switzerland). Both of them are high quality and durable products offering very high accuracy and long term stability. Choose one of them depending on your budget and site properties.

INSTALATION


Locations of the water and wastewater level stations are often difficult for installation. River banks, bridges, drains, inspection chambers and many others demand different equipment type and mounting accessories. For each of these locations PM Ecology is able to provide perfectly fitted Aqua Logger with complete mounting set that can be easily adjusted to particular location.
