1. 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.

1.1. Automatic data collection via GPRS network

The HydroLogger H40G is equipped with a GSM/GPRS data module for automatic trans-

fer of measured data from the instrument to the database on the server.

ACTIVE STATIONS SYSTEM

FIEDLER telemetry stations are characterized by long battery life and very low operating

costs with regular data transmission to the server. This has been achieved by a system

of active stations and a passive server:

▪The server is always on and waiting for data from the individual telemetry sta-

tions, which themselves determine when the data will be transmitted to the

server.

▪The system can receive data from multiple stations simultaneously.

▪The GSM/GPRS modem in the station is switched on only for the time necessary

for data transfer from the station to the server - saving power of the power bat-

tery.

▪If an extraordinary event occurs at the measurement location, the station can

immediately transmit this information to the server - the usual delay of cyclical

calling of stations by the server is eliminated.

▪The system allows the use of operationally cheap types of tariff SIM cards with-

out a fixed IP address in the stations. The fixed IP address is usually charged

for, which increases the overall operating costs of the system.

DATA SERVER SERVICES

The data server is accessible via a standard web browser. After logging in, the user can

use the services of the data server, which include:

▪generation of graphs and tables of measured values

▪exports measured values for the selected period to the user's PC

▪automatic forwarding of received data from the station to another ftp server

▪printing of graphs and monthly reports including statistical summaries

▪creating virtual stations that can contain differently averaged, summed or other-

wise adjusted data from different real stations in one graph

▪automatic sending of e-mails to preset addresses after meeting the set condi-

tions (exceeding or dropping of the measured value over the set limits, switching

on/off of the binary channel, error conditions, ...).

PARAMETERIZATION OF THE STATION REMOTELY

A special server service allows you to change the settings of the station parameters

remotely over the Internet and GSM/GPRS network via the MOST program. All previous

and current parameter

files are stored in the

server database, including

the date and time of their

change and the login

name of the specific user

who made the change.

All these services are

available to the station

user for a low annual fee,

which is incomparable to

the investment in the

equipment of your own

server and its regular

maintenance. This makes

the data collection system

accessible to users of one

or two telemetry stations

as well as to operators of a

large monitoring network.

MAP VISUALIZATION

In some applications, it may be advantageous to display the location of the station and

its current status on a map

base. The status can be

both information about the

station's trouble-free op-

eration and the measured

values of the selected

channel.

An example is the freely

accessible server

www.hladiny.cz, which

displays measured data

from hundreds of stations

installed on rivers and

streams across the coun-

try.

Incorporation of the sta-

tion into the system is per-

formed by the server administrator at the request of its owner.

2. Basic description

The Hydro-Logger H40 is

characterized by its robust

mechanical design, small size

and modern electronic circuit

concept with very low self-cur-

rent consumption. It is suitable

for direct use in outdoor envi-

ronments as well as in perma-

nently wet environments in

waterworks.

The H40 station allows you to

set up to 8 recording channels

K1 - K8 for measuring se-

lected physical quantities and 8 binary channels B1 - B8 for recording states on binary

inputs.

In addition to the recording and binary channels, the station contains 7 control channels

K9 - K15 for recording the battery supply voltage, remaining battery capacity expressed

in %, current drawn by the connected sensors during measurement, temperature and

humidity inside the instrument.

The data memory can hold up to 400,000 values including date and time of acquisition.

The capacity of the data memory is sufficient for several years of data recording in nor-

mal operation. When the memory is full, the oldest stored values are gradually overwrit-

ten. The data memory also records extraordinary events - receipt or sending of SMS,

occurrence of an input error, data transfer to the server, etc.

The H40 operates in a power saving mode, in which the instrument is hibernated most

of the time and only wakes up and takes measurements at the set archiving interval.

During the measurement period, power is supplied to the connected sensors and trans-

ducers. The magnitude of the supply voltage is adjustable from 6 to 15 VDC.

The H40G telemetry station transmits the measured values via GSM/GPRS communi-

cation to a database server. In addition, the station can send warning or informative SMS

and receive query or control SMS. Parameter settings can also be changed and FW

upgrades can be performed via GSM/GPRS data communication.

All H40 station parameters are set via the MOST program. Parameters can be changed

from a PC (laptop) via a cable connection or remotely via a web browser and data server.

A 3.6V/19 Ah (H40D) or 3.6V/28 Ah (H40G) lithium battery pack is used to power the

unit, with a connector for easy field replacement. This battery pack allows many years

of operation of the instrument with daily transmission of measured data to the server via

GSM/GPRS network. Unlike the H1, H7 or M4016 stations, the H40 station is not

adapted for external power supply connection.

2.1. Overview of program procedures and functions

The following overview briefly summarizes the programming procedures and functions

contained in the H40 station FW, which are fully available to the station users during its

parameterization and setup. Most of these functions will be described in detail in the

"Setup" chapter.

▪Calculation and storage of the measured quantity in set units of measurement

▪Non-linear signals can be corrected by a 2nd order polynomial separately for

each of the set channels.

▪Calculation of the remaining capacity of the power battery based on continuous

measurement of the current drawn from the battery

▪Separate limit alarm for each recording channel

▪Separate gradient alarm for each recording channel

▪For the duration of an alarm on a channel, you can set a different frequency of

data being written to memory and a different frequency of data being sent to the

server than in the normal state.

▪Data transmissions are performed under the FINET protocol (binary protocol

with fixed frame) or Modbus RTU. Data packet transmissions over the

GSM/GPRS network are performed under the TCP/IP protocol.

▪Regular sending of archived values via GPRS network to the Internet to the set

IP address (to the server with the MOSTNET-SERVER program installed)

▪Phonebook for 10 recipients, up to 3 groups possible

▪Alert system based on 14 user configurable SMS messages

▪Activation of sending SMS or transferring data to the server via GPRS network

periodically in time or after reaching the limit value on the measuring channel,

after activation of limit or gradient alarm, in case of sensor fault, low battery volt-

age, after activation of binary input or on request by SMS

▪Adjustable delay and hysteresis for SMS warning limits

▪25 query and command codes for creating a query or control SMS

▪Automatic insertion of the instantaneous value of the measuring channel into the

SMS text

▪Setting the time for sending daily SMS and the day for weekly SMS

▪Automatic switching between daylight saving time and standard time, automatic

time comparison with the server

▪Automatic archiving of the current parameter file on the server after each pa-

rameter change

▪The event log contained in the data memory records extraordinary events (acti-

vation of selected inputs, incoming and outgoing SMS, occurrence of error sig-

nals at connected sensors, successful and unsuccessful data transmission to

the server, etc.).

2.1. Mechanical design

The Hydro-Logger H40 is housed in a cylindrical stainless steel housing with a diameter

of 40 mm, which is terminated on one side with a K2 connector for connecting the sensor

and on the opposite side with a K1 communication connector for connecting a PC (lap-

top). The H40G variant of the instrument equipped with a built-in GSM/GPRS communi-

cation module has a small SMA coaxial connector next to the K1 connector for connect-

ing an external GSM antenna.

The robust mechanical design protects the electronic circuits from external interference as

well as from adverse climatic influences and is highly resistant to intentional and unintentional

mechanical damage.

LEVEL METER WITH TSH22 PROBE

Typically, the Hydro-Logger H40 is used as a level gauge to monitor wa-

ter level and temperature. In this case it is convenient to order the H40

station together with the TSH22 sensor and the DH40 stainless steel

mounting bracket. The bracket includes clamps for mounting the H40

station and a screw hanger for clamping the cable of the submersible

transducer (TSH22). The entire measuring assembly can then be sus-

pended from the bracket, e.g. in a borehole. The small dimensions of the

H40 station itself and the DH40 holder allow the measuring assembly to

be placed in a borehole with an inner diameter of only 50 mm.

Detail of the DH40 bracket mounting holes, the DA284 filter location

on the connector body and the TSH22 level sensor cable attach-

ment.

The special hydrostatic level sensor cable contains a capillary to com-

pensate for the atmospheric air pressure acting on the submerged sen-

sor. A semi-permeable filter located on the body of the level gauge con-

nector prevents air moisture from penetrating the capillary to the sensor

electronics and possible subsequent corrosion inside the level gauge.

2.2. Communication

Parameter setting in the station and transmission of measured data can be done either

by cable from a connected PC (laptop) or remotely via a server and GSM network.

MOST PROGRAMME

All communication between the H40 and the connected PC (laptop) is done via the

MOST program. Using this program, you can, for example, parameterize the station,

transfer measured data from the station to the connected PC or view the current meas-

ured data. The MOST program is described in detail in chapter 4 of this manual.

Parameterization of the station consists in creating the current parameter file for the ap-

plication and then saving this parameter file to the H40 station. The MOST program is

also used to archive the current station parameter file and to modify this file. A special

server function can transfer the parameter file from the server via GSM/GPRS data net-

work to the H40G station even remotely.

After purchasing a license for the MOST program, the user gets an unlimited time option

to upgrade the program.

Download the current version of MOST from the station manufacturer's website:

http://www.fiedler.company/cs/ke-stazeni/stahnout-software-most

GSM/GPRS COMMUNICATION MODULE

The H40G telemetry station contains a GSM/GPRS communication module that usually

mediates all data transmissions between the station and the user. Connecting to the sta-

tion from a PC (laptop) is therefore usually not necessary.

Measured data stored in the station is automatically transferred via GPRS network to the

database on the server at the specified time. Conversely, a parameter file is transferred

from the server to the station if any changes to the station parameters are needed. The

parameter file is transferred at the end of the data session and only if the user has changed

at least one of the parameters and placed the new parameter file on the server. The MOST

program is used to manage the parameter file.

CONNECTING A PC (LAPTOP) TO THE H40 DATA

LOGGER

Transfer of measured data from the H40 station to a con-

nected PC or setting of parameters in the H40 station can

also be done from a PC (laptop) connected to the station

with a 2 m long KP232/M12 communication cable.

On the PC side, the cable is connected via a 9-pin con-

nector to the RS232 port. If the PC or laptop is not

equipped with an RS232 connector, it is necessary to add

a USB/RS232 converter (a suitable type of converter can

be ordered with the station).

On the side of the H40 unit, the K1 connector type M12 is

used for cable communication.
