Aqua-Scope Monitor 2 Operating manual

Aqua-Scope Monitor
2
SKU: AQSWIE02
Version: 1.0.2
Product Description
The Aqua-Scope Water Monitor detects damaging water leaks. Additionally, it records the total
consumption of water in the home and the temperature and the pressure of the water. The device
applies advanced signal processing analyzing water pressure waves traveling inside the pipes of the
house water system. It consists of two devices:(a) the main body with a battery compartment, (b) the
external sensor head connected to the water pipe.
The device has two wireless communication options. When connected to your local WIFI network it will
send all sensor data and alarms to the Aqua-Scope Cloud and receive commands the same way. Your
mobile app can access the data and present current and historical values and events. When connected
to a LoRaWAN network all data and alarms will be sent to your LoRaWAN network of choice. You can
operate the device with WIFI or LoRaWAN connection or run both connections in parallel.
A single sensor can monitor the whole home or apartment and additional peripheral devices such
as Valve Motors or Flood Sensors can be assigned to the monitor to enhance functionality.
The device is powered either from an external power supply and/or by an internal ER26500 (Bobbin Cell
C) battery. If external power is available the internal battery will not be used and stays ready when
power fails.
Installation Requirements
The Aqua-Scope Water Monitor watches the water pressure and water pressure waves (water noise) of
the home water installation system. The Aqua-Scope water microphone must be connected to the pipe
system at one single point in the home. Ideal connection points are edge valves located below sinks or
beside toilets. Alternatives are 1/4 inch revision openings on pressure reduction valves, shut off vales or
other installation gear. It is recommended to find a place as low in the home as possible (ideally

basement or first floor) but it is important to find a place 'after' the Pressure Reducing Valve PRV (The
main shut off valve is typically positioned before the PRV and hence the water microphone shall not be
installed on this valve).
Further requirements are:
Next to the device is mains power for the USB-C power
plug. Otherwise the device requires a battery.
The device expects a Pressure Reducing Valve (PRV)
installed in the home. The presence of a PRV is detected
automatically. If no PRV is present the device will still work
but the functionality is limited. Please refer to the manual section 'PRV Impact' for details.
The place of installation needs reasonable coverage by your WIFI (or LoRaWAN9 network of choice.
Mechanical Installation of the Monitor
To make it short and easy – the video on aqua-scope.com/install explains the installation of the Aqua-
Scope Water Monitor step by step:
1. In case there are two edge valves under the sink, please identify the cold-water supply. Just open
hot water and check which valve warms up.
2. Close the faucet and close the edge valve by turning clockwise.
3. Remove the metal hose from the edge valve using the 19 mm wrench supplied. You may want to
have a towel on hand to catch the water leaking from the end of the hose.
4. Mount the T-shaped connector on top of the edge valve and fasten it using the 19 mm wrench.
5. Connect the metal hose to the upper end of the connector
and fasten it using the 19 mm wrench.
6. Screw the Aqua-Scope pressure sensor head into the side
opening of the connector and fasten it by hand. There is no
need to make it super-tide.
7. Re-Open the edge valve by turning the knob anti-clockwise.
8. Please check all three connections for some seconds that
there are no leaks.
9. Attach the Aqua-Scope to a suitable location using double-
side tape and plug the sensor head into the water-proof
screwable terminal of the main device. Attach the optional
water contact sensor to the small round terminal if desired.
10. Power the device using the USB Power Plug. Please use the
power supply provided within the scope of delivery. This
power supply has very low distortion factor required for precise measurements of pressure.
Reset to Factory Default
The factory default is indicated by a green/red blinking LED. To reset to factory default state push the
button right after the initial buzzer beep (but not earlier!) and keep it pushed for 5 seconds. 4 short
beeps will help you count. After 5 seconds you will see three short green LED pulses with a low-

frequency sound. Now release the button! The recessed round part on the middle of the device is the
touch button.
This process will delete all device and network settings.
WIFI Setup
Download the App “Aqua-Scope” from your App store and register yourself as new account with
email and password. You may want to use the QR codes above for a convenient access to the store.
Follow the instructions on the app. For all subsequent setups of Aqua-Scope Monitor please choose the
option “Setup new Monitor” in the Configuration menu of your mobile app.
If you don’t want to use the Aqua-Scope Mobile App you can also setup the device using any standard
web browser. Please refer to the technical manual Aqua-Scope Monitor Access - developers manual
for more information.
Part of the step-by-step guidance in the mobile app is to read your water meter and insert the current
water meter value into the app. After few weeks you will receive a push notification on your mobile
phone to redo this process ('Configuration' ->' Water Meter'). This will help to further enhance your water
consumption display accuracy.
Add more peripheral devices
The Aqua-Scope Water Monitor can act stand alone in connection with the Aqua-Scope cloud and your
mobile app or it can control further peripheral devices using a dedicated local LORA based wireless
network. Its recommended adding at least one Aqua-Scope motor servo (for ball valves or gate valves)
to shut off the water in case of an emergency or to support certain tests. You can add up to 10 additional
wireless Aqua-Scope water-contact sensors further protecting your home from water damage caused by
spillovers. Please refer to the manual of the water-contact sensors for further information.

Pairing with the LoRaWAN Network
The device supports LoRaWAN. Operating the device requires sufficient LoRaWAN coverage from your
LoRaWAN provider of choice. Your LoRaWAN service must register the new device before the OTAA
operation. LoRaWAN OTAA requires three device-specific keys for this process:
Device-EUI (unique key to identify this device)
Application-EUI (unique key to identify the service of this device)
App-Key (unique secret key to secure network connection setup)
You find the Device EUI key printed right on the device both as readable characters and as QR Code. The
QR code complies to the recommendation of the LoRaWAN Alliance.
Using the service http://io.aqua-scope.com/lora/keys.php you can download the complete set of keys
plus additional device information.
Please refer to the technical manual "Aqua-Scope Monitor Access - Developers Manual" for details
on payloads, configuration options etc.
Functions and Usage
The Water Monitor has a variety of different functions that require certain configuration values. The
default values will work in most cases but you may want to double-check and verify the settings in the
mobile app under menu item "Configuration".
Water Consumption
The device will report each consumption of water including the duration plus the consumed amount .
Ambient Sensors
The device regularly reports water pressure, water temperature, uptime since last reboot and the
incremental water consumption of water.
Leakage Detection
To detect leaks some water must have escaped from the water system. Hence, leak detection does not
protect you from leaks but minimizes the damage of leaks. Damage happens if a certain amount of
water has enough time to impact construction material and furniture.
The diagram above shows the relationship between the speed of water (in liters/minute) and the time
this water flows out. The thick curve marks the area where damage will happen (about 10 liters of water,
one full bucket). The required reaction time to a detected leak depends on the speed of the water. For
micro leakages with very low speed of water (point 1 in the diagram) its acceptable to act after few days
or even weeks while a fatal burst of a pipe requires a reaction within few seconds (point 2 in the
diagram).
Aqua-Scope uses different techniques to identify leaks in four different scenarios (A1 - A4) characterized
Users and Installation Manual: Aqua-Scope Monitor 2 (AQSWIE02)
Copyright © 2022 Aqua-Scope Technologies, Sakala tn 7-2, 10141 Tallinn, Estonia, www.aqua-scope.com

by their speed of water. The lines between the area are determined by calibration. After initial calibration
they are constantly are re-adjusted to adapt the device to changing conditions of the water system. The
four sub-areas result in different alarms because the user action on these alarms may be different.
All normal water outlets in a home limit the speed of water. Even parallel consumption of water will
not result in speed of water beyond a certain level. In case the system detects a very high speed
of water a possible root cause is a bursting pipe (Section A4). Depending on the measured speed
of water the Aqua-Scope will issue a Heavy Flow-Alarm after few seconds. Please note that an
interruption of the water supply or a manual shut-off of the water will result such this alarm type
too since the Aqua-Scope Monitor must assume that the water disappeared somewhere.
The „Usage“-scenario (section A3) is defined by speeds of water typically for normal water
consumption of toilets, appliances, or faucets. It is impossible to separate desired from undesired
water takes. Hence the max time of water flow is limited. Once this level is reached a Flow-Alarm
is issued. The factory default threshold is set to 900 s = 15 minutes and can be conveniently
changed in the mobile app in settings.
Additional protection
is provided by the external wired water contact sensor, connected to the socket of the Aqua-Scope
Monitor. This will recognize e.g. spillovers or other loss of water. A Flood-Alarm is sent out in this
case.
The most dangerous and most common type of leaks are caused by a chemical reaction in the
water pipe leading to small orifices, also called micro-leaks (section A1). Since these orifices are
very tiny in the beginning, they are usually not seen. However, these very tiny leaks indicate a
much larger problem later on. The device has a built-in process to detect these small leaks. It is
called Pipe-Check. It requires to shut off the water for about 3 minutes. Therefore, an associated
Shut-Off Valve motor servo is recommended. The application controls this process by shutting off
the water automatically (or advise the user to manually shut off before triggering the pipe check).
The completion of the pipe check is indicated with an uplink status command or in case of a
problem a Pipe-Check Alarm. The alarm includes the estimated speed of water in ml /min plus
the estimated elevation of the leak relative to the elevation of the external sensor head.
Users and Installation Manual: Aqua-Scope Monitor 2 (AQSWIE02)
Copyright © 2022 Aqua-Scope Technologies, Sakala tn 7-2, 10141 Tallinn, Estonia, www.aqua-scope.com

The “Drip”-scenario (section A2) defines flow speeds between about 100 ml/m and 2000 ml/m.
This is still quite low, but a Pipe-Check would come too late here. Hence, this range is monitored
permanently and detected leaks or dripping faucets will cause a Drip-Alarm within minutes.
Additional Monitoring
The system is permanently monitoring the water detecting pattern indicating a jamming toilet flap.
In this case a Jamming-Alarm is issued.
If the water pressure is too high the pipes may be damaged in the home. The Aqua-Scope will
determine automatically the highest acceptable pressure and report an Overpressure-Alarm if
this threshold is exceeded.
The temperature sensor inside the sensor head measures the water temperature. A Frost-Alarm
is issued when temperature falls below a certain threshold. The factory default value for this
threshold is 4 °C.
LED-Signals
red/green/blue blinking: startup
Red fast blinking (when mains powered): Alarm
Red steady (whenbattery powered): Alarm
Green/red blinking: connection to wireless network pending
3 times green blinking plus buzzer: Aqua-Scope connected to network successfully and is ready to
work
PRV Impact
An installed pressure reducing valve (PRV) is common in almost all contemporary European home water
installations. Without PRV the Aqua-Scope Monitor is still applicable but some functions are limited.
Working: Pressure Monitor, Temperature Monitor, Flood-Alarm, Frost-Alarm, Overpressure-Alarm,
Micro Leak Testing
Not Working: Drip-Alarm
Less Precise: Usage Alarm, Water Consumption Metering, Jamming-Alarm
Attention: If your water system has a PRV installed the Aqua-Scope Monitor must be
installed after the PRV (between PRV and the individual outlets).
Alarm and Alarm Clearing
All alarms are indicated by
a buzzer sound on the device,
a red LED blinking on the device,
a warning display on the home page of the mobile app including the time stamp, reason of the
alarm and a hint how to remedy the situation,
a push notification on the mobile phone that has the native app installed.
Alarms are cleared automatically if the reason for the alarm disappeared. They are kept as notice on the

mobile phone app but with green color to signal that the root cause of the alarm was removed.
Battery Operation
If the device is powered by battery all focus in on extending battery life. The battery life depends on
several factors:
Presense of a Pressure Reduction Valve: If a PRV is present the device will draw significantly less
power and the battery life extends at least by a factor of 2.
Interval of status reporting. In mains power mode the device will report its status every 20 seconds
plus it will report every start of water flow and every end of water flow. The app show individual
water flows. In battery mode this function is turned off to reduce the number of communications.
Hence, there is no visualization of individual water flows but aggregated water consumption data
only.
In mains powered mode an alarm is indicated by a blinking red LEDs plus a buzzing sound. In
battery mode the led is turns on and the time and a shorter buzzing sound is issued every 4
seconds.
All status data such as temperature of water, consumption etc are only reported once per hour (in
mains every 15 minutes)
The stand-by animation of blue led glowing is tuned of in battery mode.
