The Hydrolog HLF4 is used for measured value recording and remote data transmission from level probes, ultrasonic sensors or similar level sensors.

A new and innovative redundancy function makes it possible to have the Hydrolog HLF4 automatically verify measured values. The recorded data are cyclically transferred to the ACS portal on the Internet. There they can be analysed and processed by the authorized user from any location.

The areas of application range from groundwater monitoring, surface water measurement, landfill monitoring, to rainwater overflow logging.

The well thought-out alarm management enables the danger of flooding or even low water to be eliminated or reduced.
