AQSWIE02 WIFI Water Monitor

WIFI Water Monitor
SKU: AQSWIE02
Version: 1.0.0

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 connects to WIFI. Your mobile app help setting up the connection and gives access the data and presents current and historical values and events.
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 Water Monitor watches the water pressure and water pressure waves (water noise) of the home water installation system. The Aqua-Scope sensor head 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. Alter-natives are 1/4-inch revision openings on pressure reduction valves, shut off valves or other installation gear. It is recommended to find a place as low in  the home as possible (ideally basement or first floor). Attention: If your water system has a Pressure Reducing Valve (PRV) installed the Aqua-Scope monitor must be installed after this PRV (between PRV and the individual outlets). If no  PRV is present the device may be installed everywhere but precision of measurements is reduced. For details, please refer to Section ‘PRV impact’.
To make it short and easy – the video on aqua-scope.com/install explains the installation of the Aqua Scope Sensor Head 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 scoreable terminal of the main device. Attach the wired flood sensor to the small round terminal if desired.
10. Power the device using the USB C 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 State

The factory default state is indicated by the LEDs blinking green/red. Please push the button after the initial buzzer beep (but not earlier!) and keep it pushed for 5 seconds. After 5 seconds you hear a low- frequency sound. Now release the button! This reset sequence will delete all settings including network access credentials.

Please refer to the Aqua-Scope Developers Manual for more information, available at www.aqua- scope.com.

Functions and Usage

As soon as the unit is connected to a radio network, an automatic calibration begins. Use water normally during this time. After 24 hours at the latest, this calibration is finished. It is detected whether a pressure reducer is present, and  which standard pressures are present in the water system. You can restart the calibration from the app if necessary (configuration menu).
Every 15 minutes (when mains powered) or every hour (when battery operated) the device reports the following sensor values:

• Temperature of the water right at the sensor head.
• Pressure of the water.
• Consumption of the last 15 min/1 hour.

The sensor values can be accessed in the Aqua-Scope App or they are reported into your network of choice.
The main function of the device is analyzing the water distribution system for different kind of anomalies and report them as alarm. The following alarm types are reported:

• External wired flood sensor detects water.
• Water flow time exceeds threshold (default threshold time is 15 minute but it can be changed in the app or by configuration parameter.
• Water pressure too high (the threshold is automatically detected during calibration).
• Too heavy water flow, typical for disengaging fittings or broken pipes.
• Dripping faucet (only detected when PRV is present).
• Water about to freeze (threshold of 4 °C can be changed in Aqua-Scope App).
• Jamming Toilet Flap.
• General unusual Water Flow pattern indicating a leak.

Beside the water-related alarms the device also reports certain device-related conditions as alarm:

• No external sensor head connected
• Head present but no contact to water
• Battery Low
• Mains Power lost
• Bad communication network quality

All these alarm conditions are monitored continuously. Alarms are indicated on the device with red LED and buzzer sound (both can be disabled in the app) and they are reported into the Aqua-Scope Cloud and shown in the Aqua-Scoop  App. If the alarm condition disappears the alarm is reversed but will remain in green color in the app for information. Swiping them in the apps home page finally deleted them. Further alarm reactions such as email, push notification or even a Voice call can be defined in the Aqua Scope App.

Pipe-Check

Detecting micro leaks in the pipe system needs a special measurement sequence. This sequence takes about 240 seconds and in this time there must be ‘silence’ in the water system. Hence, it recommended to perform this so-called Pipe- Check at night. Events such as water flow or preparation of warm water will terminate this process.
During the sequence the water needs to be shut-off. Therefore, it is recommended to add a retrofittable motor to perform the task automatically at night You can define the time and the weekdays by setting a timer in the app (Configuration -> Timers) with Pipe-Check as action. If no retrofittable motor is connected to the monitor, you can still turn off the water manually before manually starting the process in the app. When the Pipe-Check indicates a microleak there is no need to panic. In most cases this will be a dripping faucet. If the result of a Pipe-Check continues to show a microleak for several days, then its time to search for the reason. The alarm message will give some guidance.
Not all water related alarms will result in shutting off the water. You can define the desired reaction on different alarm types in the app under Configuration -> Reactions on Alarm.

LED-Signals

• All colors blinking: device boots up
• Yellow blinking: Devices tries to connect to network
• Red fast blinking (mains powered) or steady: Alarm
• green/red blinking: factory default
• 3 times green blinking plus buzzer: Device connected to network successfully and is ready to work
• Blue glowing (mains powered) or all LEDs off (battery operated): Device is operating

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.

• No limitation: 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

Battery Operation

If the device is battery-operated all focus in on extending battery life. The battery life depends on several factors:

• Presence 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 and receive commands from the app/Cloud. In battery mode the device wakes up every hour only.
• Hence, every command such as open/close of the valve or setting certain parameters will be executed with delay.
• 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 turned off in battery mode.

You find an estimation of the battery lifetime in the app under ‘Devices’. With PRV the battery will last about 8…10 years, without PRV the lifetime is about 4 years.
