LoRaWAN AQSLWE01 Aqua-Scope Water Monitor

Product Description

The Aqua-Scope Water Monitor records all consumption of water in the home and it detects damaging water leakages. To achieve this, the device applies advanced signal processing analyzing water pressure waves traveling inside the pipes of the house water system. A single sensor can monitor the whole home or apartment and communicates measured values and alarms to a LoRaWAN network. The current version of the Water Monitor is approved for single-family homes and multi-family homes with one single water meter per apartment. ‘Clinical Trials’ are ongoing for installations in multi-apartment homes with more than one water meter per apartment.

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 valve (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 a mains power outlet for the USB power plug.
• 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.
• Your home needs reasonable coverage by the LoRaWAN network of choice.

Mechanical Installation

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:

•  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.
•  Close the faucet and close the edge valve by turning clockwise.
•  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.
•  Mount the T-shaped connector on top of the edge valve and fasten it using the 19 mm wrench.
•  Connect the metal hose to the upper end of the connector and fasten it using the 19 mm wrench.
• Screw the Aqua-Scope microphone into the side opening of the connector and fasten it by hand. There is no need to make it super-tide.
•  Re-Open the edge valve by turning the knob anti-clockwise.
•  Please check all three connections for some seconds that there are no leaks.
•  Attach the Aqua-Scope to a suitable location using double-side tape and plug the microphone into one of the two sockets on the main device. Attach the optional water contact sensor to the other outlet if desired.
•  Power the device using the USB Power Plug. Please use than power supply provided within the scope of delivery. This very power supply has a very low distortion factor required for precise measurements of pressure.

Pairing with the LoRaWAN Network
The device supports LoRaWAN Class A and OTAA activation. Setting configuration parameter #21 = 1 allows changing to Class C. Reboot of the device is needed after the configuration value was set. 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 all three keys printed out as label printed out inside the package. Furthermore, you find a QR-code with the Device-EUI right in the device. Using the service http://io.aqua-scope.com/lora/ you can download the complete set of keys plus additional device information. Please contact support@aqua- scope.com to receive your access credentials for this service. During pairing the LED will blink red/yellow. Once connected successfully the LED will glow green indicating normal operation.

TTN Integration

The Things Network (TTN) is a free community-based LORAWAN network with a global reach. If there is a TTN Gateway near your home you can use the water sensor without any further hardware If no – may be this is a good reason to join the community with your own gateway.’

After the registration of the device with TTN please use the “HTTP Integration”
to forward all data to ‚https://io.aqua-scope.com/lora/in.php‘. Convenient
access for test purposes is possible using ‚https://io.aqua- scope.com/lora/ui.php?dev=DEVICE_EUI‘. The link ‚https://io.aqua- scope.com/lora/lora.zip‘ allows downloading the scripts for change, inspection and further use on your own server and integrating the data into your own application.
Please note that the mentioned scripts can only be used for devices from Aqua- Scope. Device EUIs from other manufacturers will not be processed.
Functions and Usage
Water Consumption
The device will report each consumption of water including the duration plus the consumed amount. This function is deactivated on default to comply with the “fair use” policy of most LoRaWAN networks but can be activated using configuration parameter #21 bit 4.
Ambient Sensors
The current water pressure, the ambient temperature, and the incremental water consumption since the time of the last report is sent every 15 minutes. The reporting period is defined in configuration parameter #29.
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 by their speed of water. The lines between the area are determined by calibration. After initial calibration the 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 Water 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. Two thresholds define the alarm condition:
• Max time in seconds, factory-default is 900 s = 15 m
• Max amount of water in liter, factory-default is 200 liters
• Exceeding these thresholds will cause a Usage-Alarm.
• Additional protection is provided by the external wired water contact sensor, connected to one of the two sockets of the Aqua-Scope. 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 orifice, 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. 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 water microphone.
• 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 to detect 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 internal temperature sensor allows issuing a Frost-Alarm when a certain threshold for frost danger is hit. The factory default value for this threshold is 4 °C.

LED-Signals

• Slow glowing of the green LED: Normal operation, no flow of water
• Faster blinking of the green LED: Flow of water
• Red fast blinking: Alarm
• Red/Yellow/Green LED light up one time with beep right after power-up: ongoing Pipe-Check Green/red blinking: connection to wireless network pending
• Sequential red LED blink: Fatal hardware error
  time blinking: general error
  times blinking: FLASH memory error
  times blinking: RAM memory error
  times blinking: ADC access error
  times blinking: LORA access error

PRV Impact
An installed pressure-reducing valve (PRV) is common in almost all contemporary European home water installations. Without PRV the Aqua-Scope Water 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

Alarm and Alarm Clearing

All alarms are indicated with

• a buzzer sound on the device,
• a red LED blinking on the device,
• a LoRaWAN alarm message sent to the LoRaWAN Application Server

Alarms are cleared automatically if the reason for the alarm disappeared. Only the Flow-Alarm must be cleared by a wireless command or pushing the single button on the device even when the sensor does not have contact with water anymore. The recessed round part on the middle of the device is the touch button.
If no alarm is cleared pressing the button will issue a heartbeat signal sent to the LoRaWAN network server.
Scope of Delivery

• Aqua-Scope Water Monitor main device
• Aqua-Scope water microphone with 80 cm cable and audio jack
• 3/8 Inch water pipe connector (T-shaped)
• One external water contact sensor with cable and audio jack
• USB power cable and power supply
• 19 mm wrench to unfasten and fasten the 3/8 Inch connections of the pipe connector Manual

Reset to Factory Default
The factory default is indicated by a green/red blinking LED. To return to factory default 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.
