Use of H40
HydroLoggers H40 are suitable for building monitoring net-
works in the water industry, for monitoring surface and ground-
water levels, in environmental monitoring projects and in many
other similar applications where the small size of the instru-
ment, its robust design and the long life of the power batteries
are advantageous.
Type H40G is equipped with a built-in GSM/GPRS communica-
tion module, which is used for automatic transfer of measured
and archived data to the database on the server and for possible
sending of warning SMS. The communication module can also
be used to remotely make any changes to the control parame-
ters.
The modern electronic circuitry of the Hydro Logger with its very
low current consumption and the controlled power supply of the
connected sensor allows the device to operate without changing
the battery pack for more than 10 years, even with daily auto-
matic data transmission via GSM network to a database server
on the Internet.
In applications where a GSM network is not available or auto-
matic data transfers to the server are not required, the H40D var-
iant, which lacks the GSM/GPRS communication module, can
be used for data acquisition and archiving. In this case, the
measured and archived data must be read out to a connected
PC (laptop) using the MOST program.
TYPICAL APPLICATIONS
▪
Measurement of levels and temperatures in boreholes
and open streams
▪
Measurement of levels in sewer manholes and water
reservoirs
▪
Temperature and humidity measurement
▪
Accurate measurement of up to 6 temperatures using
TEP-06 transmitter and Pt100 sensors
If it is necessary to monitor several different physical variables in
one location, it is preferable to use telemetry stations such as
STELA-3, H1 or more sophisticated units such as M4016 or H7,
which have more inputs for connecting external sensors.
