Description

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.

 

Function
The battery operated data logger serves as a link between the measuring point e.g. with a level sensor from the Hydrolog® series and the data platform on the Internet.

Depending on the setting and sensor, a battery can achieve a service life of more than 5 years. It is possible to operate the Hydrolog HLF4 using an external power supply or PV modules instead of batteries.

The data transfer to the ACS portal on the Internet is carried out automatically by the strongest mobile operator on site. It does not matter whether there is 2G GSM or 4G LTE network coverage. The SIM card is already integrated in the device. The user does not need any further mobile phone contracts.

The multifunctional input makes it possible to connect standard sensors as well as energy-saving digital sensors.

The built-in redundancy function makes it possible to compare two measured values from different sensors. This means that measured values can be verified and an alarm is triggered automatically at an adjustable difference. This results in the highest level of measurement reliability combined with a minimum of control measurements.

Operation on site is via a Bluetooth® interface in connection with an app. No special devices are required for this. A smartphone, tablet or laptop is sufficient for operation.
