Datalogger for groundwater monitoring

Dataloggers are widely used tools in the field of monitoring the level, temperature and more generally the quality of groundwater.
These devices are equipped with a pressure and temperature sensor, memory and internal battery so that the operator can install them at the desired point, thus allowing continuous control of multiple points at the same time.

The recording duration and, consequently, the number of data collected by the instrument itself vary according to the data recording interval, defined by the user, and the size of the data logger memory.
The acquired data can be simply downloaded from the device to the computer or sent directly remotely via telemetry for reading and subsequent characterization of the water body.

The HCC group offers its customers the data loggers of two of the most prestigious international brands: Heron Instruments and Aquaread.

Heron Instruments has the dipperLog NANO in its catalog, in a version with or without compensation cable, with 32,000 memory data.
The dipperLog NANO is a suitable instrument for monitoring the level and temperature of water in wells, open water or during flow tests. This instrument is available with full scale (where full scale means the maximum water column above the pressure sensor of the instrument), respectively of 10 m, 30
m, 60 m and 120 m.

The instrument is recovered from the well once the acquisition campaign is finished and the data is downloaded to your computer.

The version without suspension cable is combined with the barLog NANO for recording atmospheric pressure values.
The NANO barLog can be associated with several NANO dipperLogs, as long as they fall within a radius of 15 km (variable according to the orography of the area), and allows you to separate via software, from the data read by the Dipperlog, the value of the atmospheric pressure, thus obtaining precisely the variations in the water level.

In case the DipperLog is installed with the direct reading cable, it is possible to perform real-time reading
, data download and reprogramming of the instrument directly from the piezometer head, without having to extract it from the installation point.

The Vented Logger (with compensation cable) is used as an alternative to the dipperLog NANO +
barLog NANO configuration for long-term monitoring of groundwater depth and temperature. The Vented
Logger is available with the same full scale as the dipperLog NANO and does not require the barLog NANO for
barometric compensation.

Aquaread offers on the market the LeveLine, for the measurement and recording of water level and temperature values, and the LeveLine-CTD which also measures electrical conductivity and salinity

The LeveLine and the LeveLine-CTD both have a memory that can acquire up to 500,000 data and can acquire data with a speed of up to 10 data per second. Made of titanium, they are suitable for both clean and salty water.
These models are also available with or without a compensation cable (absolute pressure) and can be integrated with remote data transmission systems.
