Aqua-Scope AQSLWE02 Operating manual

Aqua-Scope Monitor
SKU: AQSLWE02
Version: 2.0.0
Product Description
The Aqua-Scope water monitor detects water leaks and records the total water consumption in the
house as well as the pressure and temperature of the water. The device applies advanced signal
processing and analyzes the sound waves, which move in the domestic water distribution pipes when
water is taken or there are leaks. Water is a very good conductor of sound. A single sensor is
therefore sufficient, to monitor the whole house or apartment. In addition, to the sensor other
peripheral devices such as valve motors or flood sensors can be associated to extend the functionality of
the overall system.
The device consists of two parts:
Main housing for signal processing and radio communication with battery compartment.
The external sensor head is connected to the water pipe. The stainless steel sensor head has a
silicon sensor mounted in silicone oil for highly accurate and low-noise pressure measurements in
a wide operating range. The measuring range for pressure is between 1 and 10 bar. The sensor
values are converted into digital values directly in the measuring head to suppress interference
from the connection to the main housing. In addition, the temperature of the liquid medium is
measured directly at the stainless steel diaphragm and is therefore very precise.
The sensor can send an alarm message if freely definable threshold values are exceeded or not reached.
The sensor's polling frequency can be set between 0.1 second and several minutes and defines the
battery life. For a measuring interval of 1 second, a battery life of approx. 10 years is calculated.
The device communicates via LoRaWAN as a Class A device and can also be operated as a Class C
device via configuration parameters.
The device is powered either via an external power supply with USB-C power supply unit or via an
optional internal ER26500 battery (Bobbin Cell C).
Both the sensor head (IP67) and the main housing (IP65) are waterproof and can be used outdoors or in
particularly humid and/or dirty environments.

Installation
The Aqua-Scope sensor head must be connected to a single point
in the house's piping system. Ideal connection points are angle
valves located under sinks or next to toilets. Other options
include 1/4-inch access openings at the pressure reducer, shut-
off valves, or other installation devices. It is recommended to
choose the lowest possible point in the apartment (ideally in the
basement or on the first floor).
Attention! If a pressure reducing valve (PRV) is installed, the Aqua-Scope monitoring device must be
installed between the pressure reducer and the individual outlets. If no PRV is present, the device can be
installed anywhere, but the accuracy of the measurements will be lower. Details can be found in the
section "Impact of Pressure Reducer."
To keep it short and simple, the video at aqua-scope.com/install explains the installation of the Aqua-
Scope water monitor step by step:
1. If two angle valves are present under the sink, please
identify the cold water supply. Simply open hot water and
check which valve warms up.
2. Close the tap and shut off the angle valve by turning
clockwise.
3. Remove the metal hose from the angle valve with the
provided 19mm wrench. Have a towel ready to catch the
water coming out of the end of the hose.
4. Attach the T-shaped connector to the top of the angle
valve and secure it with the 19mm wrench.
5. Connect the metal hose to the top of the connector and
secure it with the 19mm wrench.
6. Screw the Aqua-Scope pressure sensor head into the side
opening of the connector and secure it by hand. It is not necessary to tighten it too much.
7. Open the angle valve again by turning the knob counterclockwise.
8. Check all three connections for leaks for a few seconds.
9. Attach the Aqua-Scope to a suitable location with double-sided tape and connect the sensor head
to the main device. Insert the flood sensor into the audio jack if necessary.
10. Turn on the device using the USB-C power plug. Please use the included power supply. This power
supply has a very low harmonic distortion, which is necessary for precise measurements.
Alternatively, insert a battery.
Connection to LoRaWAN Network
This device, with its three keys (Dev EUI, Join EUI, Join Key), needs to be registered with a LoRaWAN
network operator that covers the device's location with radio signals.
If you purchased the device directly from Aqua-Scope's online shop, use the email address used for the
Users and Installation Manual: Aqua-Scope Monitor (AQSLWE02)

purchase and the public device key (Dev EUI) on the website https://aqua-scope.com/lora. You will
receive a message with all three keys to the provided email address. The public key is also printed on
the device as a 16-digit number and as a QR code for scanning. The QR code and 16-digit number are
also printed on the outer packaging.
If you purchased the device from a dealer, the dealer will provide the three keys. If they do not, please
contact [email protected] by email.
Immediately upon inserting the batteries or connecting a power supply, the device will attempt to
connect to the LoRaWAN network using the three keys you provided. The LEDs will blink during this
process. After approximately 25 seconds, this process, called 'JOIN,' will either be successful or aborted.
In the latter case, the device immediately enters sleep mode.
If, for any reason, the sensor loses connection to the server, an automatic reconnection process, called
'Rejoin,' will take place. This process repeats whenever the device attempts to send a message to the
LoRaWAN network.
Pressing the button always initiates a LoRaWAN communication, leading to a 'Rejoin' as explained above.
Please observe the Duty Cycle regulation—sending messages or Rejoins too quickly in succession may
be ignored by the LoRaWAN network.
Device Operation
Remote Access
The device is accessible via LoRaWAN commands. lease consult your LoRaWAN provider for details how
to access the data. Please refer to the sections below for information on the payload and the payload
decoding.
Measurement Values and Alarms
The device measures the pressure and temperature of the water in the pipe where the sensor is
installed multiple times per second.
Additionally, the sensor analyzes all acoustic waves occurring in the water. Since water is an
excellent transmitter of acoustic waves, a single sensor is sufficient to capture all acoustic events in the
house from a main water meter, pressure reducer, or pressure booster. These three devices block the
transmission of sound waves in the water pipe. By analyzing the sound waves, the sensor distinguishes

between normal water consumption and various anomalies, each reported as an alarm to the user.
The following alarms are possible:
1. One of the wired or wireless flood sensors has detected water. This is typically triggered by a leak
near the respective sensor.
2. The water pressure has risen above the threshold set in the app or through configuration
parameter 6. The reason for this alarm could be malfunctions of a pressure reducer or backflow
preventer to the hot water system.
3. The water pressure has fallen below the threshold set in the app or through configuration
parameter 7. The reason for this could be a pipe break; however, the water may have simply been
turned off.
4. The external sensor is not connected to the main device.
5. The external sensor is connected to the main device but not connected to a pressurized water line.
6. The water temperature has either fallen below the value set in the app or configuration parameter
11 or risen above the value in the app or configuration parameter 16.
7. The Pipe-Check has detected a microleak. There is a separate chapter in this manual for 'Pipe-
Check'.
8. The duration of water draw has exceeded the value set in the app or configuration parameter 10.
This may indicate a leak or be triggered, for example, by filling a swimming pool.
9. A clogged toilet has been detected.
10. Water is beginning to flow, likely caused by a leak due to specific acoustics.
The alarm is transmitted to the app and forwarded there via push notification and (configurable in the
app) as an email or voice message. If the condition that triggered the alarm has been resolved, the
alarm will be automatically cleared. It is also possible to clear the alarm by double-clicking on the
monitor's button, even if the alarm condition has not been resolved. The alarm will then remain locked
until the next power-on.
Sensor Data
The sensor measures water pressure, water consumption, and water temperature, and sends the values
every 15 minutes, along with operating time, battery consumption, and battery voltage, via LoRaWAN.
Calibration
To correctly evaluate acoustic signals in the water, the sensor must be calibrated. This happens
automatically after the device is connected to the radio. The calibration process takes about 24 hours.
During this time, water withdrawals may already be displayed, but they may still be roughly incorrect.
Incorrect displays will occur, especially if the normal water pressure fluctuates significantly during the
calibration period. This can happen if the target pressure of the pressure reducer is changed during this
time or if the device is first tried on the table before being connected to the water line for final
installation.
In this case, and also otherwise if needed, the calibration can be repeated. Please refer to the section
LoRa Commands below for details on the command needed.

Effect of a Pressure Reducer
An installed pressure reducer (PRV) is common in modern European house water installations. Without a
pressure reducer, the Aqua-Scope monitor is still usable, but some functions are restricted:
No Restriction: Pressure monitor, temperature monitor, flood alarm, frost alarm, overpressure
alarm, microleak test (Pipe-Check)
Less Precise: Consumption alarm, water consumption measurement, clogged toilet
Pipe-Check
The detection of micro-leaks in the pipe system requires a special measurement method called 'Pipe-
Check.' This process takes about 240 seconds, and during this time, the water system must be in a "rest"
state, meaning no water withdrawal should occur. The 'Pipe-Check' should ideally take place at night as
events like water withdrawal or water heating can disrupt the process without issues.
During the 'Pipe-Check,' water must be shut off. Therefore, it is recommended to install a retrofit motor
that performs this task automatically at night. The time and days of the test can be set in the app as a
timer (Configuration -> Timer) with 'Pipe-Check' as the action. If no retrofit motor is connected to the
monitor, water can still be manually turned off, and the 'Pipe-Check' can be started manually in the app.
If the Pipe-Check indicates a micro-leak, there is no need to panic. In most cases, it will be a dripping
faucet. If the result of a Pipe-Check shows a micro-leak over several days, it's time to investigate the
cause. The alarm message provides further hints on where the leak may be located.
LED Indicator
The device features a tricolor LED (red/green/yellow) to signal different operational states. The LEDs only
remain continuously lit when powered by an external source. In battery mode, the LEDs remain off after
the startup sequence to conserve power.
Yellow glowing or blinking in a sequence: Device is booting up
Red/green blinking: The device is in the factory state or searching for a LoRaWAN network.
Slowly breathing blue: Device is connected to the internet and in standby mode (only in external
power mode).
Flashing red: Alarm is active. The cause of the alarm was sent by LoRaWAN.
Button Operation
By pressing the button once, twice, or three times in quick succession, the following functions can be
activated:
Once: In battery mode, the device is awakened, the green LED lights up, and additional commands
can be entered.
In the wake-up state (external power, awakened from battery mode), pressing the button
once sends a status message via WLAN.
Users and Installation Manual: Aqua-Scope Monitor (AQSLWE02)
Copyright © 2023 Aqua-Scope Technologies, Sakala tn 7-2, 10141 Tallinn, Estonia, www.aqua-scope.com

Twice: Existing alarms (LED blinking red) are cleared.
Three times: Currently not assigned.
Note: In battery mode, the button must be held down for about 1 second (until the green LEDs light up)
to wake up the device. Afterward, the second and third clicks can be performed as needed.
Battery Operation
The sensor can be operated with an external power supply, a battery, or both simultaneously. The status
at the moment of powering on defines the device's operating mode. If mains voltage is present at the
moment of powering on, the device will remain in power mode until the next status report (default every
15 minutes), even if mains voltage fails and a battery is inserted. The battery then operates as a backup.
If the sensor is started by inserting a battery, it will switch to battery mode. This means that some sensor
functions are shut down to save power:
The status LED remains dark.
A local alarm is neither indicated acoustically nor by a red LED.
The device responds only slowly to incoming commands (on average, about 10 seconds in power
mode, up to one hour in battery mode).
The device can no longer receive alarms from external wireless flood sensors.
The sensor data is sent only hourly instead of every 15 minutes.
If the device has LoRaWAN communication capability, it will attempt to join the LoRaWAN network
only once (JOIN).
An estimate of battery life can be found in the app under "Devices". With a pressure reducer, the battery
lasts about 8 to 10 years, without a pressure reducer in the water pipe, the lifespan is about 4 years.
