Getting started
These instructions assume
•You are unfamiliar with the Hydro-Logic®Flexi Logger 100
•You have purchased the logger with a Timeview package, including SIM
•You have ordered the logger with a sensor
•You have ordered the Pre-wiring and configuration service
The instructions cover the most important aspects of logger operation. They
should be carried out before the logger is installed on site.
Switching the logger on and off
The logger is shipped in the OFF state. Press and hold the power button (A) until
a green flash is seen in the LED window (B)
The logger is now ON. You should see a blue LED flash every two seconds.
There are other patterns of LED activity, which are described in Status LED flash
patterns.
You can switch the logger off by pressing and holding the power button until you
see a red flash. The logger is now off.
Note that the internal clock is stopped when the logger is switched off, but the
configuration and stored data are preserved. You need to reset the logger clock
after it is switched on so that data from the sensor is correctly time-stamped.
This can be done either by Resetting logger clock with Timeview or Resetting the
logger clock with Harvest

Hydro-Logic®Flexi Logger 100
User Manual
6 April 2018 Page 11 of 62
Connecting to Timeview
With the logger switched on, press and hold the dial-out button until you see a
yellow flash on the LED.
The logger will then begin a series of steps to call out to Timeview. Progress can
be followed using the Status LED flash patterns, or you can just wait for a few
minutes until the red, blue and green flashing has stopped and the logger has
gone back to a single blue flash every 2s.
Now see Finding your data on Timeview –you should be able to see that your
logger has connected successfully.
If the mobile data signal is poor, the logger will try several times to transfer data
to Timeview, so there is no need to press the dial-out button more than once.
Recording test data from the sensor
If you have ordered the Pre-wiring and configuration service, the sensor can be
immediately connected to the large SCA connector on the logger body.
If you need to wire your own sensor, see the section Sensors for more
information.
Once the sensor is connected, you should ensure that the clock is reset (either by
Resetting logger clock with Timeview or Resetting the logger clock with Harvest)
This will clean any blank data points that were recorded with no sensor

connected, and ensure that data points from the sensor are correctly time-
stamped.
Now leave the logger to record some data. The logger will be configured to take
measurements every 5 or 15 minutes, so leave it for half an hour or so.
Finally, either press the dial-out button to send data to Timeview or read the
logger with Harvest. You should now see data points from your sensor(s) in the
Harvest plot or the Timeview Logger Profile.

Hardware configuration and installation
Device overview
Refer to the block diagram below. The Hydro-Logic®Flexi Logger 100 is
controlled by a low-power microcontroller. There is a sensor interface and
storage on local memory for the logger configuration and typically several months
of time-series data.
A 3G mobile data modem is used to transfer data to a remote data collection
system via either an internal and or external antenna. The modem includes a
standard SIM interface.
The orange lines show the power distribution. There is an internal battery which
can typically provide years of operation. External power can also be used. An
HLC is a small on-board rechargeable battery which provides boost power for the
modem and sensor as required.

Sensors
The Hydro-Logic®Flexi Logger 100 can be used with many sensor types.
Sensors fall into these general categories:
•SDI-12 sensors
•4-20mA sensors
•Tipping bucket rain gauges and other digital sensors
SDI-12 sensors
SDI-12 sensors are “smart” sensors which can measure multiple parameters in
engineering units using the industry-standard SDI-12 protocol.
An SDI-12 sensor uses 3 wires and is connected to the Flex Logger 100 sensor
connector as shown.
Sensor address
Before you can read an SDI-12 sensor, you need to specify the sensor address
by configuring the logger with Harvest. Follow the steps in Connecting the device
to ensure that you can communicate with the logger.
First, you need to find the address of the sensor. Ensure that there is only one
sensor connected to the logger.
From Harvest, run the command Start Wizard/Advanced logger options/SDI-
12/Request Sensor Address:

Hydro-Logic®Flexi Logger 100
User Manual
6 April 2018 Page 16 of 62
When an SDI-12 sensor is detected on address 0 the following output will be
displayed:
Now you can test the sensor by reading it using that address. Run the command
Start Wizard/Advanced logger options/SDI-12/Request Measurements from
Sensor:
If you see measurements in the log above, the sensor is working OK.
When you configure the logger for this sensor, you need to specify this address in
the SDI-12 tab:

Hydro-Logic®Flexi Logger 100
User Manual
6 April 2018 Page 17 of 62
You also need to specify which parameters you want to log, with the Enabled
check boxes.

Hydro-Logic®Flexi Logger 100
User Manual
6 April 2018 Page 18 of 62
While you are here, check the Calibration box and ensure that the “Range From”
and “To”values include the range of measurements you are likely to see. If they
don’t, you will get gaps in your data when the sensor is outside this range.
Addressing multiple SDI-12 sensors
Follow the above procedure to address and test each sensor. Give each a
unique address, starting at 0.
When you are configuring the logger, use the Add Sensor button in the SDI-12
tab. It will create a new SDI-12 tab, and you can set the address of each sensor:

Hydro-Logic®Flexi Logger 100
User Manual
6 April 2018 Page 19 of 62
Wiring multiple SDI-12 sensors
Multiple SDI-12 sensors share the same 3 wires on the Hydro-Logic®Flexi
Logger 100 sensor connect. They must be wired neatly for reliable performance
on site.
Hydro International offers two products to help with this:
Two Sensors
If you have two sensors, a CA-SPLITTER (part no PDA9100.1005) can be used
to neatly connect them to the logger.
The two connector leads are different lengths, so the connectors can both fit
inside the steel tubing below a PT enclosure. Use Size 8 Key Clamp so there is
enough space for both sensor cables.
The CA-SPLITTER can be used with vented sensor cables.
An extra 4-way sensor connector is included with this part.

Hydro-Logic®Flexi Logger 100
User Manual
6 April 2018 Page 20 of 62
More than two sensors
If you have more than two sensors, Hydro International offer a junction box
specifically designed for connecting multiple sensors to the Hydro-Logic®Flexi
Logger 100. This is part number PDA1100.3020
This junction box has clearly labelled PCB connectors and an option for external
sensor power.
This junction box is too large to fit inside a PT Enclosure.
Power for SDI-12 sensors
The Hydro-Logic®Flexi Logger 100 provides 12V power for sensors. Up to
120mA current is supplied –the total for all connected sensors must not exceed
this.
Sensor power is not continuous –it is switched on 5s before sensor activation.
Additional warm-up is provided as requested by the sensor.
Most SDI-12 sensors work with switched power, but some require a continuous
12V supply. In this case, an external battery or DC power supply must be
provided. Consult documentation supplied with the sensor.
