Water quality measuring stations

IM001738

Quality measurement of surface waters with state-of-the-art sensor technology.

Logotronic integrates a wide variety of sensors for water quality measurement in measuring stations. In addition to the products of our partner Eureka, we also offer individual sensors from different manufacturers for connection to our measuring system. The measuring stations are either mounted on land or on floating platforms. With the integration into Gealog Net, you can immediately access your measurement data and save yourself the manual reading of the measurement data.

Gealog TG

IMG_1087

State-of-the-art data logger.

The Gealog TG offers a wide range of functions for collecting your measurement data. Alarm functions in case of exceeding/falling below a limit value as well as freely configurable calculated measured values. The measurement data are transmitted either via mobile radio or Ethernet, but can also be read out directly on the device via USB. Furthermore, the Gealog TG offers an optional full graphic display for easy configuration of the unit. The internal time is synchronised via NTP. Sensors can be connected to the data logger via RS485, RS232 or SDI-12 interface. With the Gealog measuring interfaces you can connect all common sensors to the Gealog TG. The IQC (integrated quality control system) ensures consistent data directly in the data logger. The data logger is used in the scientific field, for long-term monitoring and in automatic measuring stations in hydrology and meteorology. Due to its low power consumption, it can be operated by battery or solar panel in remote locations and is thus independent of the rest of the infrastructure.

Gealog ftp

Level measurement with remote data transmission

The GEALOG ftp is an energy-efficient data logger in a compact format. Nevertheless, it offers a high degree of adaptability thanks to its modular design. The robust stainless steel housing is equipped for the toughest measuring tasks and can be attached directly to a level pipe. Data is transferred directly to an FTP server via the integrated GPRS modem. With recording at 15-minute intervals and daily data transmission, the integrated battery pack (which can be replaced by the user) enables uninterrupted operation for one year. Furthermore, internal parameters (battery voltage, temperature) are also recorded and transmitted.

Gealog Net

GEALOGnet overview

Data visualisation in our web portal.

Gealog Net is the online solution for visualising and managing your measurement data. Your measurement data is displayed in a modern web application. Hydrographs and tables are created in panels and are freely configurable. Several panels can be arranged in any order on a dashboard, so you can quickly get an overview of your collected data. In your personal account you have no limit regarding the number of dashboards, so it is possible for you to create your own dashboard for each type of analysis, which you can access immediately if required and which does not require any further effort. The measurement data can also be exported directly from Gealog Net as a CSV file and can be directly imported in this form by most programmes. Alarms can be defined directly in the programme, so you immediately receive a notification by mail if, for example, a limit value has been exceeded.

Eureka

Multiparameter probes

Logotronic has been active in the water quality monitoring sector for years. To complement our own products, a few years ago we took over the representation of Eureka, one of the world’s most renowned producers of multiparameter probes. Eureka multiparameter probes can be used stand-alone for e.g. manual measurements or autonomous long-term registration, or they can be connected to a Gealog measuring station for e.g. remote data transmission to the Gealog Net server.

Solinst water level meters

Water quality

Water level meters for manual level measurement.

Solinst water level meters are used to measure the water level in water level pipes, well shafts and boreholes. We offer different models that measure not only the level but also the temperature and conductivity of the water.
