Aqua-Scope PREWIE02 Operating manual

Water Pressure
Sensor
SKU: PREWIE02
Version: 1.0.0
Product Description
The Aqua-Scope pressure sensor records the temperature and pressure of the water. 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 sensor head is screwed into inspection openings of existing
water pipes or other suitable locations via a ¼ inch thread. If no
inspection opening is available it is possible to use the edge
valve below a sink or beside a toilet. For this option the
installation is described below.
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 screwable 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.

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 your mobile app
store. Follow the instructions on the app.
If you don’t want to use the Aqua-Scope Mobile App or if you want to integrate the device into your own
monitoring system you can also setup and operate the device using any standard web browser. Please
refer to the Aqua-Scope Developers Manual for more information, available at www.aqua-scope.com.
Functions and Usage
Every 15 minutes (when mains powered) or every hour (when battery operated) the device reports the
following sensor values:
Pressure of the water,
Temperature of the water right at the sensor head.
The sensor values can be accessed in the Aqua-Scope App or they are reported into the network when
integrated into third party systems. The device offers a low watermark and a high watermark threshold
that can be defined using the mobile app. If the valued are exceeded an under pressure or overpressure
alarm is issued.
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-Scop 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.
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
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.

Disposal Guidelines
Users and Installation Manual: Water Pressure Sensor (PREWIE02)
Copyright © 2022 Aqua-Scope Technologies, Sakala tn 7-2, 10141 Tallinn, Estonia, www.aqua-scope.com

Do not dispose of electrical appliances as unsorted municipal waste, use separate collection
facilities. Contact your local government for information regarding the collection systems available.
If electrical appliances are disposed of in landfills or dumps, hazardous substances can leak into
the groundwater and get into the food chain, damaging health and well-being.
