3. Description
This manual is valid for the following device version
- Hardware from 2.0 and after
- Firmware from 2.1 and after
The Flow Data Logger FDL400 suitable for flow measurement in partially filled channels or
pipes.
The evaluation is performed according to the flow formula Q = VA.
A combined measuring sensor, mounted on the bottom or the wall of a channel detects the flow speed V
in m / s according to the Doppler principle. About a sound beam that shines against the flow direction in
the medium, the speed data is collected and further processed in the processor.
The integrated pressure sensor is used to detect the level in m;
above this value each perfused segment surface is again in the processor through a pre-programmed
channel cross section calculated in m2.
With the two multiplicands will calculated the sum Q in l / s.
The programming of all necessary parameters can made via 16 buttons on the front-panel keyboard.
The clear 4 lines display the individual values appear
- Velocity
- Level
- Flow
- Totalizer
The measuring sensor is powered from the FDL400 device with the necessary voltage. The two values for
flow rate and liquid level are directly on the sensor 4-20 mA signal is available. This allows the device to
be mounted further away from the location on your channel. Without any further installation work is
usually sufficient to cable extension of the probe.

4.4 Connection Diagram
The current outputs are not isolated from the power supply.
The switching outputs are electrically isolated by optocouplers from the device power supply and
therefore require a separate power supply. This can, for example, come from a connected controller (PLC)
or from another source.

The unit has 4 switching outputs.
The switching output Q4 is switched on so-called security mode. This can be output as alarm conditions
such as power failure or sensor failure. The output is switched on correctly-working device, ie, it is in
tension. In the case of a not powered or not properly operating unit of output is switched off, ie, he is de-
energized (alarm state).
In the case of a disconnected or defective sensor, the output also turns off.
Sinks the analog input under about half of its nominal zero value of 4 mA (about 2mA), so turn off the
output and thus signals an alarm. The message on display shows !! Alarm !! - Cable break ".
Accouterment
1. In the first moment of the keyboard operation, the backlight of the display will automatically turn on.
During device operation, the display is then illuminated, so a pleasant operation is possible. About 10
minutes after the last operation of the keyboard, the display backlight will turn off automatically. This is
for a low power consumption, on the other hand to avoid unnecessary heating devices and thereby also
the increasing of life.
2. Measurement data are stored on an SD card (Secure Digital Memory Card). This is on top of the unit
under an openable flap. The presence and correct operation is indicated by lighting an LED to the side of
SD card. The saving of measuring data is visible by the flashing of this LED.
Measurement will stored on a daily basis. That is, for every day a new log file is created. Each log file has
the name of the log day, eg, 20140908 for the day 2014/09/08.
These are text files that can be opened, edited and archived with any standard spreadsheet software
(Excel, LibreOffice etc.)
3. The device can also be operated without an SD card. However, it can then not be stored measurement
data.
4. The unit has a mini-USB (AB). This is also on top of the device under the opening flap. An Update of
the operating software is with the bootloader on this interface possible.
5. In the device software under "Function 1" four types of channels selectable (circle, rectangle,
trapezoid and V-shape).
In cases other than those pre-programmed channel shapes it is necessary to provide a sketch of the
channel shape with dimensions available.
The customer then receives an SD card on which this channel is programmed.
The customer can then select "Function 1" its specialty channel with the additional choice of whether the
channel should be included in the instrument software or should only be read from the SD card.
After taking over in the device software, the SD card can be removed from the device when no data
needs to be stored.

Diagram and explanation of „Function 98“
The "Function 98" is useful for large channels or filling levels.
Since the flow rate distribution is non-linear in a channel, but is similar to a hyperbola, it may be
necessary to calculate a logarithmic curve at high flow levels from low flow levels relatively linear flow
rate curve.
This is necessary because of the velocity measuring sensor is able to measure up to a filling level of
about 400mm safely. An increasing velocity at higher filling levels can not be measured and then
calculated with the "Function 98".

6.1 Reading data from the SD - card and processing in a spreadsheet program
To read the data must be taken the SD - card from the device and plugged into the appropriate card slot
of a PC.
In the period in which the SD - card is not present in the device, no data is stored.
These memory idle time can be circumvented by inserting of another SD - card.
The measurement data are stored according to a preselected time step in a so-called log file (eg
20150320.log = data from 03.20.2015).
For every day a new log file is created automatically. The log file of the day begins at midnight and ends
at midnight course again.
The saved data format is a text file that corresponds to the Excel format and can be practically applied
and processed in any spreadsheet program.
As separator is a space.
Example:
With the most spreadsheet programs, it is possible to design curves, graphs, and statistical analysis.
