INTRODUCTION
Online capability
WARNING
LeakNet is the complete online water management product provided by Quensus.
Using LeakNet, water consumption can be visualised anytime from anywhere in the world. If a leak
is detected, an alert is immediately sent to the user via email. If desired, LeakNet can automatically
shut off the water supply, so no water damage is caused in the event of a leak.
The LeakNet Base (pictured) can connect up to 4 meters, so it has the potential to measure the
water ow through 4 different pipes, but most applications will involve just one. A valve can also be
connected, but can be omitted if there is no wish to turn off the water supply. Almost any pipe size is
accepted, and meters/valves supplied by Quensus come in standard sizes.
The LeakNet Base contains the connection to the Internet via WiFi, and is mains supplied.
You will manage and monitor your LeakNet online using a
service called FlowReporter.
Register for your account at www.FlowReporter.com.
If equipment is installed or used in a manner not speci ed in this document,
the product may not work as expected, and the leak protection capabilities
may be impaired. Please contact us if you have any problems or are unsure.
Page 5
Find the stopcock
Decide where the LeakNet will be placed - this will normally
be just after the stopcock, where the water enters the
building. This will usually be coming up from the ground.
1.
Install the Base
Choose a location to mount the Base and check WiFi
connectivity. Wire the cables from the meter(s) and valve
to the Base, making sure to use the cable glands. Screw
on the front of the Base, clip in the inserts which hide the
screws, and then connect the power adaptor.
3.
Test online
Run a nearby tap. Online, select the name of your new Base,
and then click “Close valve”. A few seconds later, the water
will stop owing. Click the sensor name, then “View” then
“Real time” then “Open valve”. You will see the graph change
as the water is turned on.
5.
Install valve and meter
Make sure the valve (optional) and meter are facing the
correct way (arrow pointing in the direction of ow) and
install in the proposed location. Up to 3 more meters, or up
to 20 temperature sensors can also be installed.
2.
Connect to WiFi
With the “Status” light ashing blue, use your smartphone
or computer to access www.FlowReporter.com online.
Login and select “Register new Base”. Follow the on-screen
instructions. Con gure the Base online by selecting the
ttings used in the above step.

INSTALLATION GUIDE
Before you begin
The Base uses WiFi to communicate over the internet, and requires mains power.
Before installing, decide where the LeakNet Base will be located:
● Within 10 meters of plumbed ttings,
● Within 10 metres of a 100-240V 50/60 Hz mains socket,
● Within range of WiFi (use your mobile phone to check for WiFi signal). Also ensure you have
access to the name of the WiFi connection and password.
If WiFi is not available, a standard 3G router can be supplied to provide the wireless connection. Data
rates are 4MB per day as a maximum.
Location Power WiFi
The Base should be wall-
mounted and located no more
than 10 meters aways from
plumbed ttings.
The Base should be located
no more than 10 meters aways
from a mains plug socket.
The Base should be located
within range of WiFi. Use a
smartphone to check the
connection is at least 2 bars.
<10m
< 10m
Tools required
● Phillips head screwdriver
● 2mm at head screwdriver
● Pipe cutter (suitable for your pipe size)
● Adjustable wrench/spanner (suitable for your plumbing ttings)
● PTFE tape
● Drill (if wall mounting)

Plumbing instructions
1. Assemble all ttings.
With push t ttings, make sure the rubber washer is
clean, and hand tighten.
With compression ttings, use about 25 turns of
PTFE tape around the thread, and then use a wrench
to tighten.
Watertight connections between the valve and
meter can easily be achieved, in most cases, with 3
rubber (or bre) washers. Be sure to place the valve
before the sensor (as far upstream as possible).
For 15mm and 22mm connections, a exible hose
(with tap connector) can also be used for ease of
tting. However, exible hoses can restrict ow
so are not recommended for areas with low water
pressure.
If you are in any doubt, we recommend professional installation by a quali ed
plumber.

2. Turn the water supply off and drain the system (or up until the next stopcock
downstream).
3. Remove any dried paint on the pipes where the connections will be tted.
4. Plumb in the ttings, making sure the arrows on the ttings match the direction of
water ow.
5. Make sure the pipes and ttings are assembled securely, and turn the water supply
on.
6. Check for leaks and tighten any ttings.
7.
Optional: Earth bond either side of the installation together if necessary. Ask a
quali ed electrician if you are unsure.
8.
Optional: Re-lag the pipework for insulation against freezing.

Wall-mounting instructions
LeakNet should be wall mounted with 5mm screws at a minimum. Make sure the
appropriate wall plugs are used and that the length of the screws are not long enough
to protrude the other side of the wall.
1. Position the LeakNet Base rear on the wall. To ensure maximum WiFi exposure,
position the Base at least 30cm away from metal objects, including pipes, and other
electronics.
2. Using the appropriate drill bit, drill through the plastic enclosure and wall.
3. Remove the LeakNet Base rear and insert wall plugs.
4. Replace the LeakNet Base rear and screw into the wall plugs.
The LeakNet Base and its power supply are not waterproof and should be installed in an appropriately
safe place. The plug socket should remain accessible after installation in case of emergency.
Page 11
INSTALLATION GUIDE
Wiring instructions
Up to 4 water meters and 1 valve can be connected to the terminal blocks on the circuit board, as
pictured below. The exact wiring will depend on your conguration.
1. Thread the wires coming from the meter(s) and valve through the cable glands.
2. Take about 5mm of the insulation off each wire so the bare conductor can slot into the terminal
blocks.
3. For each wire, press the terminal block button down and insert into hole, then release button.
Use the wiring guide on the next page to determine the correct holes to use. Each input will have
an associated position (1, 2, 3, 4) - it does not matter which one you use, as long as the correct
conguration is recorded. If only one water meter is used, simply use terminal block 1.
4. Finally, place the LeakNet Base front onto the wall-mounted back, screw into place and use the
plastic inserts to hide the screws.
Power
A suitable 12V DC power adapter will be supplied with the kit. If the distance to the nearest plug
socket is more than 1.5 metres, an extension cable (3mm diameter in black or white) can be provided
to extend the reach by an extra 10 metres.

Thresholds and alerts
An alert is sent if either of the thresholds have been exceeded. Exceeding the “alert” threshold sends
a minor alert, and exceeding the “shut off” threshold sends a major alert and shuts off the water.
Here is an example situation where the ow of water begins at 17:30 and the thresholds are
1. Alert threshold = 30 minutes or 60 litres
2. Shut off threshold = 2 hours or 240 litres
24
Minor alert
At this point in time, there has
been 60 litres of continuous
ow, therefore exceeding the
rst threshold
Major alert
At this point in time, there has been
2 hours of continuous ow, therefore
exceeding the second threshold
Total consumed
This line shows the total amount
of water consumed so far ( in litres
shown on the right axis)
Flow rate
This line shows the current ow
rate at a point in time (in litres per
minute shown on the left axis)
Normally, the valve would close and the water would be turned off after a major alert, however there
may be times when you expect an exceptional amount of water usage and do not want the water to
turn off.
In these cases, you can either disable the valve before the expected time of usage (shown on page
19), or click the link in the minor alert which disables the valve for that event only.
Note: All users who have permission to control the valve will receive alerts with a link to disable the
valve for that event.
