Aqua-Meter Clamp with Wi-Fi

SKU: AQMWIE01
Version: 1.0

Product Description

The Aqua-Meter Clamp measures the flow and temperature in a water pipe using a "Time of Flight" measurement method and transmits the data wirelessly. It is easily attached to the existing water pipe from the outside without the need to interrupt the water supply. The best position is right after the water meter. Due to adjustable transducer positions and innovative software the Aqua-Meter Clamp works with pipe diameters between 15 and 50 mm and it supports all contemporary pipe materials such as PEX, PEX AL, copper, PE, or steel. It registers water consumption from approximately 1 liter/hour and it distinguishes between normal water usage, dripping faucets, stuck toilets, pipe breaks, etc. And alerts the user.

The device meets all the requirements of the European Metering Directive (MID). With a footprint of only 60 mm above the water pipe and a length of 110 mm, the device is very slim and short, making it easy to find a suitable spot to install.

The Aqua-Meter Clamp can be powered either by an USB-C or by two standard AA batteries. Whenever an external power source is available, it is used independently of the inserted batteries.

Control of the system is centralized through a mobile phone app using WiFi communication. Furthermore, data can be transmitted to an MQTT server or an HTTP 'webhook,' facilitating integration with modern Smart Home systems.

Measurement Principle

The water sensor clamp utilizes ultrasonic waves and the "differential time of flight (DTOF)" method to measure water flow. In this method, two ultrasonic transducers, called transducers, are employed to send signals in opposite directions through the pipe and water. The signal sent by the upstream transducer travels along the direction of water flow and is detected by the downstream transducer. The second signal sent by the downstream transducer moves against the direction of water flow, progresses more slowly, and meets the upstream transducer later. The difference in travel time between the two signals is directly proportional to the speed of the water in the pipe and thus the flow rate. To better understand this method, one can imagine it like swimming in the current of a river. By swimming upstream and downstream and comparing the time it takes to cover the same distance in each direction, one can estimate the speed of the water flow in the river. Similarly, in the case of the water sensor clamp, the movement of the transducers generates a wave that serves as a swimmer to estimate the speed of the water flow.

The test signal of the device has a frequency of 1 MHz and is of very low power, making it inaudible and harmless to humans and animals. Furthermore, the sound waves of this high frequency are strongly attenuated by the atmospheric pressure of the air and, in practice, cannot radiate beyond the pipe. Therefore, the water sensor clamp will not disturb people or other devices.

Installation

tbd.

Connecting to WLAN

After inserting the two batteries or connecting the external power supply, the LED in the button blinks red/green, indicating the factory state.

You can connect the sensor to a Wi-Fi network of your choice only in the factory state. The factory state can be restored by waiting for the first beep sound when inserting the batteries or connecting the power supply, then pressing and holding the button for 4 seconds (counting four red blinks helps). If the LED lights up three short red flashes, please release the button.

In the factory state, when powered by batteries, you have exactly 120 seconds to connect the device to Wi-Fi. After that, the sensor goes into sleep mode to conserve battery life. You can wake up the device in this state by pressing the button, and the LEDs will blink red/green again for 120 seconds, indicating readiness to connect to Wi-Fi. In network operation, the factory state, indicated by red/green blinking, is continuously maintained.

For communication via Wi-Fi, three different methods are available:

Conveniently through the Aqua-Scope App: Please read the description of app installation and usage in the "Device Usage" section or directly in the app. There is no separate manual for the individual functions of the app.
Through the built-in web server: In the factory state, the device acts as an open Wi-Fi access point with the SSID 'Scope.' You need to connect your mobile device or PC to this SSID and open the page http://192.168.4.1 in a web browser. Now, enter the SSID and WPA key of the home Wi-Fi. If you want to control your device later via the Aqua-Scope app, you need to have an Aqua-Scope account and provide this email address so that the device can be associated with your account. Under "Advanced Options," additional settings for the device's communication options can be made (MQTT, JSON, Bluetooth, local web server). In the manual "Aqua-Scope Developers Manual", there is more information on this. The 'Save' button saves and activates the values. If they were correct, the red/green blinking stops. Otherwise, the process must be repeated with the correct SSID and WPA key.
Through Bluetooth:

In the factory state, the Bluetooth interface on the device is active and can be used for initial configuration. This can be done through any Serial Bluetooth application. However, it is more convenient on a PC or an Android mobile phone with Bluetooth capabilities. Open the webpage https://ble.aqua-scope.com in the Chrome browser, connect to the Bluetooth device 'AQS-XXXXXX' (XX is the device ID), and enter the SSID and WPA key via the webpage form. More information is also available in the "Aqua-Scope Developers Manual".

Operation of the Device

Communication with the Device

If the sensor is connected to the local Wi-Fi, its functions can be utilized through various communication channels (simultaneously if desired):

App on Mobile Phone, PC, Pad: The Aqua-Scope App is not available in your mobile phone's App Store. We use a Progressive Web App (PWA) available at https://app.aqua-scope.com. Open this link in the system browser (Chrome@Android or Safari@iOS) to access almost all app functions. Android may prompt you to install the app on the device. On iOS, create a shortcut to the website on the desktop to receive push notifications if allowed.
MQTT Server: When configured accordingly, the sensor's status information is sent to the configured MQTT server. The MQTT service must be enabled, and your own MQTT server/port/login information must be set in the device. Refer to the Aqua-Scope Developers Manual for more information.
Custom Web Service: Most smart home gateways allow the reception and display of sensor data through plugins using 'Webhooks.' More information can be found in the Aqua-Scope Developers Manual.

Sensor Data and Notifications

The Aqua-Scope App displays:

Temperature history (measured next to the transducers)
Consumption within an interval (15 minutes in mains operation and 60 minutes in battery operation)
Current battery status during battery operation

Additionally, the app, email, and/or push notifications show various alarm messages. In the app, under "Configuration->Alarm Messages," you can set how a specific alarm should be displayed and reported. In mains operation, alarms are also indicated directly on the device through red LED blinking and sound.

Alarm clearing: Alarms can be cleared directly on the device by a double-click, even if the alarm condition persists. Alarms are automatically reset when the alarm condition or the error to be alarmed about no longer occurs. Reset alarms are displayed in the app's event history.

Alarm Messages and Causes

Long Water Withdrawal: Water flows for an extended period. The default threshold is set to 15 minutes, adjustable in the app under 'Configuration.' The alarm is automatically cleared when water consumption stops.
Too Intense Water Withdrawal: Indicates a potential pipe break. Flow consistently exceeds the allowed threshold for one minute. The default threshold is set to 28 liters/minute, adjustable in the app under 'Configuration.' The alarm is cleared if intensity drops below the threshold or stops.
No Water Flow: If no water is needed for an extended period (30 days threshold), water should be turned off, and pipes emptied or regularly activated (e.g., flushing the toilet) to prevent damage. The alarm is cleared when water withdrawal is detected again or no water is detected in the pipe.
Negative Water Withdrawal: Unusual water flow direction, usually impossible due to check valves. Triggered if water flows in the wrong direction for 30 seconds. Cleared when normal or no water flow is detected.
No Water in the Pipe: Possible during water shutdown or repairs, rendering the sensor inoperable. Air bubbles in the pipe are also possible. Refer to installation conditions.
Stuck Toilet: No damage but unnecessary water consumption. A stuck toilet produces a characteristic consumption pattern and can be easily identified. Usually resolved by pressing the flush button. The alarm also ends when no blockage is detected.
Dripping Faucet: Any water withdrawal above measurement inaccuracy and below normal consumption is considered a dripping faucet. If minimal water flows for at least an hour, an alarm is triggered. Investigate and address potential causes such as a small leak in a water line (microleakage).
Device Tampering Attempt: After the sensor is initially attached to the pipe and functions normally for at least 6 hours, it activates a self-protection mechanism triggering an alarm for actions like separating the electronic part from the base, removing the base from the water pipe, or opening the electronic housing. Note that changing batteries will always trigger a manipulation alarm.

LED Indicators

Red-green slow alternating blink: Device is in factory state and needs connection to a wireless network.
Green slow breathing: Device is operational, and no water withdrawal is currently happening.
Red blinking: Alarm.
Green blinking: Water withdrawal.
Red-green fast alternating blinking: Firmware update.
Red-green-yellow cycling: Mounting aid active.
No LED: Either no power supply or in battery operation.

Button Operation

Single click: In battery operation, wakes up the device and sends a status message.
Double click: Clears alarm message.
Triple click: Activates mounting aid. Stop with a single click.

Power Supply

The device can be powered either through an external USB-C power supply or by using two off-the-shelf AA batteries. Whenever an external power source is available, it will be used independently of the inserted batteries. In the case of external power supply, the LED will illuminate green to indicate normal operating status.

In battery operation, power consumption must be minimized, leading to the following changes:

In normal operation, the LED is turned off.
In the event of an alarm, the LED and buzzer are only briefly activated at longer intervals.
No individual water consumptions are reported.
The total consumption is transmitted only once every hour.
The minimum detection threshold for dripping faucets is slightly increased.

All other functions of the device, such as leak detection, drip detection, etc., continue to operate.
