1. Introduction
The exact and real-time knowledge of the discharge is an important task in the fields of
hydrography, water storage management, irrigation and prevention of natural hazards. It is the
requirement to calculate water structures and for an economical management of water
resources. It is the base for simulations of hydrological processes with mathematical-physical
models.
The RQ-ADMS radar sensor is a continuous measurement device for the contact-free
determination of the discharge of open rivers and channels. It combines two contact-free radar
measurement methods in one system. On one hand the water level is measured by a transit
time measurement of a radar signal. On the other hand the flow velocity at the surface is
simultaneously determined by the principle of Doppler frequency shift. These two
measurements are internally combined and provide the discharge using a predefined mapping
of the measurement site.
Backwater situations caused by inflows, weirs and downstream standing water bodies show
no stable relation between water level and discharge. In many situations hysteresis effects
with different relations for rising and falling water levels occur. Therefore the determination of
such relations is affected by a substantial uncertainty. Only the additional information of flow
velocity, given by the RQ, allows the calculation of the discharge under these difficult
conditions.
Due to the contact-free measurement approach the radar sensor usually can be installed on
bridges or extension arms without expensive structural measures in the river or channel. The
radar sensor is located outside the danger area of flood events and allows a low maintenance
operation over many years.

4.1. Battery and Sim-Card installation
Remove all four thumbscrews
Remove upper housing cover
Slide out batterie drawers
Instert batteries

9
Connect the batteries as shown
Push battery drawers back in
4.1.1. SIM Card
If the used SIM card is locked by a PIN code, the PIN code has to be configured in the MRL-7
menu. A wrong PIN code in the MRL-7 menu will lock the SIM card as soon as the device was
started three times! If the SIM card is not locked by a PIN code, this menu item must be set to
“-1”.
It is possible to change or deactivate the PIN number, but not within the MRL-7. This has to be
done with another device (e.g. a mobile phone). The call forwarding option has to be
deactivated in every case by the phone provider to disable the mailbox.
A valid SIM card has to be placed in the marked slot of the integrated modem. It is important
to assure thecorrect plug direction. The SIMcard also has to be placed straight into the modem
and has to be locked in the device after the insertion:
Insert sim card in the marked slot
Further instructions are available in
the MRL-7 manual.

4.2. Software
All device settings can be adjusted with Sommer’s software Q-Commander.
The software is shipped on a thumb drive with your RQ-ADMS unit.
To edit the parameters with the PC software Q-Commander, the “Expert” mode must be active
(for more details see Q-Commander manual):
Set “Expert” mode
The PC software Q-Commander highlights the edited parameters. After uploading the changes
to the MRL-7 and the RQ-30/RQ-15, the modified parameters are active (for more details see
Q-Commander manual).

4.7. Data transmission via HTTP/FTP
When data are transferred to a server via HTTP or FTP protocol all data stored on the logger
will be sent to the defined server(s).
The first transmission includes all data recorded so far. Further transmissions will include all
data recorded since the last successful transmission.
In case the data could not be transferred (e.g. because of bad cell reception) the “missing”
data will be sent on with the next succesfull transmission.
4.8. Modem
Data recorded by the integrated MRL-7 can be transmitted to user defined servers (HTTP
and/or FTP).
The modem supply voltage is controlled by the data logger. It is only switched on when a data
transfer has to be performed to save on power consumption. Additionally the modem is
switched on for one hour per day to allow for remote connections to be established with the
system.
To make the modem capable for data transmission a SIM Card has to be inserted. Next, the
APN data and the mobile network defined for the SIM card have to be selected.
4.8.1. APN Data
Establishing a GPRS connection requires setting the correct APN access data (server, user
name and password) which depend on the used network operator.
The APN settings can be set either manually or the settings are chosen from a predefined list
with the software Commander:
Press the [Select APN] button
