Introduction
1Introduction
Thank you for choosing our product. We hope you will enjoy using the device.
HyQuest Solutions manufactures, sells, installs and operates quality instrumentation, data loggers and communication
technology. Products are designed with passion for environmental monitoring and with a deep understanding of the
quality, accuracy and robustness needed to fulfil the requirements of measurement practitioners in the field.
The present User Manual will help you understand, install and deploy the device. If, however, you feel that a particular
information is missing, incomplete or confusing, please do not hesitate to contact us for further support!
iLevel-GW is an IP data logger designed for very low power data acquisition of level and temperature in groundwater and
surface waters. The system can be easily expanded into a multi-channel monitoring device by adding optional sensors for
water quality monitoring. By default, an iLevel-GW comes with a coupled water level and water temperature sensor
accurate to 0.1 % FS. The vented pressure sensors auto-compensate for atmospheric pressure and temperature variations
providing a corrected reading at all times.
iLevel-GW loggers are equipped with a 433 MHz near field radio interface for all local communications. The wireless
technology allows to connect to an iLevel-GW installed in a borehole or other 2” pole without any need to remove or
even touch the device.
At the time of order, users can choose from a series of distinct communication types:
1. 2G/GPRS (General Package Radio Service).
2. 3G/UMTS
3. 4G/LTE Cat M
All of these data communication methods use IP protocols to transmit data directly to the server via cellular network.
Using that technology, it becomes possible to set up even large monitoring networks which can still be handled
comfortably and require little maintenance. Furthermore, using the cellular networks is a cost-saving way to transfer the
data, as it doesn't require any further hardware to be installed in the field.
Network time information is used to sync the internal clock of the data logger, allowing for perfect timing at all times.

Installation
2Installation
This chapter contains the following subsections:
§ Mechanics
§ Fitting into Measuring Tube
§ Fitting the Antenna
§ Fitting the SIM Card
§ Assembling and Changing Batteries
§ Initial Commissioning
2.1 Mechanics
The housing consists of two V4A-steel casing pipes and a plastic fitting inside, in which the battery and the electronic
system are located.
The joints and gaskets must not get dirty or damaged!
Prior to assembling the device, joints and gaskets must be checked and lubricated (silicone grease or O ring grease).
Attention: Don't use force!
Replace the desiccant (i.e. Silica gel(R)) as necessary. The desiccant bag is located at the cover panel of the electronics.
Important: Check the O-ring seal every time the device is reassembled. Any damaged seal must be replaced! Depending on
which type of desiccant is used, the humidity should be not higher than 20%. Humidity above 20% might indicate broken
seals. At a humidity higher than 50% the electronic is at risk! Advice: most of desiccants can be re-generated by drying at
120 °C…150 °C for 20 minutes.
2.2 Fitting into Measuring Tube
For installation in a 2 " tube, the border of the cap of the data logger is placed on the edge of the tube.
To fit the logger into a 3” or 4” tube, an adapter ring is required. Adapter rings of 3” or larger have an opening for light
plummets. The antennas are fitted individually: For underfloor installations underfloor antennas are available. Those are
clamped between the frame and the lid.
Helical antennas are fitted onto the lid for above-floor measuring points. For fitting the antenna, the lid is pierced with an
appropriate drill bit in the centre. Using that hole the antenna can be screwed onto the lid. Inside buildings, a stub
antenna can be screwed onto the logger. Once the logger is fitted, a comparative measurement should be performed
using a light plummet.
2.3 Fitting the Antenna
Note: The device comes with a standard GSM-plug (FME) for the antenna. Various antennas can be connected using the
FME plug. Your cable may be brought out through a small hole or a small notch. It is recommended to mount the antenna
on a metallic surface. When connecting the antenna, plug in the plug as far as possible for optimal contact. Please do not
unnecessarily tighten the knurled screw. Note: In case of low signal strength a slight change of the antenna position can
cause a significant improvement in signal strength (just a few cm). If the signal is too low at all, antennas with higher
transmitting / receiving power or directional effect can be a good solution. We will be glad to help you finding the
optimum antenna for your area!
2.4 Fitting the SIM Card
Important: To open the card holder, press your finger on the drawer slightly and push it in the direction which is marked
"Push Open", so that the latch releases the drawer. To lock, simply press your finger on the drawer slightly again and push
it in the other direction which is marked "Push Open" until the latch closes.

Installation
2.5 Assembling and Changing Batteries
Possible types of batteries are 2 mono-D-cells with 1.5 Volt or 1 lithium DD 35Ah with 3.6V.
Caution: To avoid damage, use appropriate batteries only!
To assemble the battery, remove the steel casing pipe which covers the battery compartment.
For this, twist off the ring nut and pull off the casing pipe.
Attention: Please mind the polarity of the batteries. Inserting the battery incorrectly may blow the fuse (which can only
be repaired at the factory) or even damage the electronics.
The electronic comes with a backup capacitor which can compensate a power outage for a short time (i.e. during a battery
change), so it doesn't lose data like date and time.
If the outage was too long, the device will reboot, which is indicated by the green LED blinking about 10 times. After that
the device is ready to use. The time has to be synchronized again.
2.6 Initial Commissioning
Due to European law, devices will be shipped deenergized only. See Assembling and Changing Batteries on how to fit
the batteries.

3.1.4 Parameters
§ Global Parameters: The measuring time intervals are set here.
§ Period: Enter measuring interval. The minimum for this parameter is 1 minute for GPRS-transmission. If
Monitoring on the site, a 2 second interval can be used in combination with the live mode (i.e. pumping tests) If the
interval is set as min, sec or hour can be selected from the drop-down menu next to the field. If you set an interval
of less than 1 minute, the program will refuse to transfer the parameters to the logger if the transmission intervals
are too large to all data measured in the interval to be sent in a single transmission.
§ Period-Offset: From a period of 5 minutes or more, the logger automatically selects the first measurement, the
next "modular" time, i.e. at a period of 1 h, this would be the next full hour. If for example a period of 12 hours is
selected, the measurements would be made, at 0:00 and 12:00. With the "Period Offset" the time of measurement
can be postponed. If an offset of 2 hours is selected for example, the measurements would be made at 2:00 am
and 2:00 pm.
§ Alarm period: Interval of measurements in case of an alarm
§ Name: Custom name for each logger (for example, tag number, street name). IMPORTANT: The name cannot
contain special characters.
§ Live mode (Real-Time): The live mode is used for continuous local transmission of data via radio to a receiver.
When the real time mode is active, the device sends the currently measured data to the shell software which
displays this data in the main window. This allows to monitor the water level in real-time, for example when
changing water levels by pumping. The shortest possible measuring period is two seconds.
§ There are 3 modes for the live mode:

© 2022 HyQuest Solutions 13
Configuration
§ Intelligent: Logger detects when a receiver is in range and then sends data automatically in the measuring
interval set.
§ Always: The logger will always send data, not matter whether there is a receiver in range or not. This setting
requires continuous power!
§ Off: The logger does not send any data.
§ HK-Counter: Set transmission interval of internal self-monitoring values. 1 = with every normal transmission. 10 =
with every 10th transmission. In case of alarm the self-monitoring values will be collected at each measurement.
§ Log HK: Select, which self-monitoring values shall be collected. The following options can be selected: Supply
(battery), temperature (Housing temperature) and humidity (Housing inside humidity).
§ Parameter Set: Shows which set of parameters is currently selected and cannot be changed. The number contains
the logger ID, year, month, day, hour, minute, second (e.g. 100012_20090812080050: Logger Nr 100012 _ 12.
August 2009 at 08:00:50) The number is set every time parameters are sent to the logger.
§ GPRS / GSM Setup: Opens the window for transmission and modem settings.
§ Channel Parameters: Settings of the channel parameters can be changed here. Channel 1 is for the measurement of
water level / tapping, channel 2 is for measuring the water temperature.
§ # 1: means channel 1 is selected. Switch the channel to be edited by clicking the arrow up / down buttons.
§ Type: indicates which value is measured in this channel and cannot be changed manually.
§ Unit: Choose the Unit to be measured.
§ ID: This parameter is intended to mark the measuring point, for example, in a database. As long as "0" is set, this
value has no effect. Values from 1 to 65535 can be entered. The value entered here will be listed in the table
headings of the exported data. Whether and how this information will be taken into consideration when importing
the data is the responsibility of the importing software.
§ Action: Each action can be activated by checking.
§ Log channel: Measured data of this channel will be saved when this option is checked.
§ Check alarms: Check this option if you want to set special alarm events (e.g. shorter measuring and
transmissions intervals).
3.1.5 Scale
§ Offset: Offset (available if no pressure sensor is used for the water level): This value will be subtracted from the
measured value (e.g. if the value should be displayed as height above sea level). Note: positive numbers are
subtracted from the measured value, negative numbers are added!
§ Multi: Default setting is 1.000000. If a minus (-) is set before the first digit, the value entered becomes negative. Use
this to select whether water column or tapping should be measured. The adjustment value can also be calculated
under the tare button. Furthermore, the density of the water can be set here. The value 1.000000 is calibrated for
fresh water. Depending on the salinity, the value has to be reduced (i.e.: 3% salt content = 0.997000).
§ Tare: Opens the tare window (see Tare ).
§ Alarm: If the thresholds entered here are exceeded or fallen below, the device will switch to alarm mode. High: If the
measured value falls below the value entered here, the alarm is activated.
§ Low: If the value entered here is reached or exceeded, the alarm is activated.
§ Power Up Wait: warm-up time for the sensor (enter 1000 ms for PTM/N from STS)
§ Sensor min / max.: Not required if a pressure sensor is used. If slower sensors are used, a period of time can be set for
the measuring time. Settings depend on the sensor type.
§ Type: Drop Down Menu. Choose between SDI (for general SDI sensors i.e. temperature), SDI12-Pressure (for the
pressure channel of the iLevel-GW and wireless sensor (to connect more sensors via near field radio)
§ No measure, use cached values: must be enabled if a sensor sends multiple values (i.e. pressure and temperature)
§ Index: Numbers of sensor channels (i.e. pressure = 0 as first channel and temperature = 1 as second channel.
§ S.Nr.: SDI 12 address of the selected sensor (default is 0)
§ Cmd.: 0 means SDI command m!, which triggers measuring

3.2 GPRS / GSM Setup
§ General Settings
§ GSM/GPRS Mode: Switch the modem on or off. By default, the modem is switched on.
§ GSM PIN: Enter the PIN of the SIM-card here, if required.
§ Min. Temp (°C): Enter the temperature until which the modem should remain active. The default is -10 °C for
alkaline manganese batteries and -25 °C for lithium batteries. It is not recommended to enter temperatures lower
than the default temperatures. If the temperature falls below the temperature entered here, the logger will keep
measuring, but send the data not until the temperature exceeds the limit entered here.
§ Allow Roaming: When enabled, the modem is allowed to use foreign networks. When disabled, only the home
network will be used. This option becomes important when the device is operated in regions close to the border.
§ Stay online: The modem will be operated continuously, so data can be sent every minute. Attention: This feature
increases the power consumption!
§ Verbose: Show detailed information about the internet connection. Useful for finding connection errors.
§ GSM period: Set the transmission intervals in which the data is transmitted. The minimum for this setting is five
minutes. Use the drop-down menu to switch between seconds, minutes and hours.
§ GSM Offset: Sets the time for the data transmission to the server. If, for example, the interval is set to 24 hours and
the offset is set to 6 hours, a transfer is performed daily at 6 o’clock. If the interval is set to 12 hours and the offset
to 6 hours, a transfer is performed at 6 o’clock and 18 o’clock.
§ GSM alarm period: Set the transmission intervals in which the data is transmitted in case of an alarm. The minimum
for this setting is five minutes. Use the drop-down menu to switch between seconds, minutes and hours.
§ Network parameter
§ GPRS APN: (Access Point Name) The GSM Access point provided by the GSM network provider.
§ PPP-User and PPP-Password: Also provided by the GSM provider. Can be left empty often.
§ GPRS repeat: By activating the check box the logger is allowed to repeat transmissions up to 3 times in case a
transmission has failed. For different reasons, such as high network load, transmissions can fail from time to time.
If this option is enabled, waiting for the repeated transmission and sending again, consumption battery power.

Configuration
Therefore, it can make sense to disable the option. If disabled, the collected data will be transmitted during the
next planned transmission.
§ Internet-Parameter
§ Internet Server: Enter the address or the ip number if the server to which the data should be sent.
§ Important: Always enter the address without 'www' at the beginning. For example, enter sensor manager.net
instead of www.sensormanager.net.
§ Script: Enter the location of the PHP script which receives the information on the server.
§ E-MAIL Format: When the data is transmitted to the sever, the server can send the data to an e-mail address. You
can choose between plain text e-mails or html formatted e-mails. The data is attached to the e-mail either as a
binary file or as a plain text file.
§ E-MAIL address: If you want to receive the data via e-mail, enter the e-mail dress to which the data should be sent
here.
§ GRPS Synchro.: When enabled, the logger will synchronize its clock with the server every time a transmission is
performed.
§ Auto Delete: When enabled, the logger will delete all logged data when 95% of the memory is used. This will
happen only if all data has been transmitted successfully.
§ GPRS Offset (sec): Time difference between the logger and the server in seconds. The server’s clock is mostly
operated in GMT mode (Greenwich without summer time). When using a logger in another time zone (e.g. Berlin,
Rome = GMT+1) the value to be added to the time must be entered here. For example, GMT+1 requires a value of
3600 seconds to be entered here.
§ Alarm Receiver
§ Alarm: E-Mail Address #1 - #4: You can enter up to four e-mail addresses to which a mail will be sent in case if an
alarm. Important: The alarm set here is performed by the logger via a script on the server.
§ OK: Confirm the new settings by pressing the OK button and then transfer it by clicking the Transfer button.
§ Cancel: Close the current dialog without saving any changes.
3.3 Two Point Calibration
Perform a linear calibration of a sensor. Therefore, 2 points need to be calibrated. The points can be calibrated one after
one or both at on time.
§ Y1,Y2 (nominal): Enter the measured value of the sensor

Custom requirements for items sent to HyQuest Solutions for warranty or non-warranty repairs: Check with your
national customs/tax authorities for details, processes and paperwork regarding tax exempt return of products. Typically,
special custom tariff codes are available (such as HS Code = 9802.00) that verify the item is being returned for repair and
has no commercial value. Please note that the customs invoice / dispatch documents should also clearly state: “Goods
being returned to manufacturer for repair – No Commercial value”. It is mandatory to have any returned goods
accompanied by a commercial invoice on headed paper. HyQuest Solutions reserves the right to charge the customer for
time spent rectifying incorrect customs documents.
Note: Please ensure that your goods are packed carefully and securely. Damage that occurs during transit is not covered
by our warranty and may be chargeable.
