Thanks for choosing the CubicMeter
The CubicMeter is a smart water meter that helps you understand how much water you consume,
while also protecting your home from leaks by constantly monitoring. It is recommended that one
CubicMeter is installed per inlet pipe, i.e. one on the hot water pipe and one on the cold water pipe,
in order for the system to cover both lines in case of leaks and to improve the system’s water flow
analysis and predictions.
The CubicMeter is extremely easy to install, and it requires no previous experience to perform.
Depending on the model It works on pipes between 15 mm - 25 mm outer diameter, and on the
following materials: AluPex, PEX, chromed and unchromed copper. This guide will help you get your
CubicMeter up and running.
Still stuck?

INSTALLATION GUIDE
To install the CubicMeter, you must first locate the inlet pipe(s) to your home, before they branch out
to the different outlets, such as the shower, toilet, etc. Make sure that the water pipes are not bent
or damaged and do not contain any air bubbles. If the installation is not made correctly, Quandify
cannot guarantee metering accuracy.
1- Acceptable position.
2- Acceptable position.
3- Not recommended, air build-up may occur.
4- Acceptable position.
The device may be rotated vertically around the
pipe if needed.
4. Remove the activation sticker. Select pipe
setting by holding the sticker over the IR-eye and
releasing when on the correct pipe.
(See full pipe list on previous page).
Example of Copper 22mm pipe chosen
Example of PAL 20mm pipe chosen
5. Verify on the display that the device measures
correctly by turning on the water flow for at
least 60 seconds.
If symbol “no sensing” is shown, verify steps 1-4
or try another mounting position/rotation on
the pipe.
Note: The device will start saving data automatically after 1 hour in pipe selection mode. If the activation
sticker is put back on for 15s over the IR eye within 1 hour, after it has been removed, the device will
revert to its packaging state.

FUNCTIONAL WATER FLOW TEST
1. When the proper pipe has been selected, open any water tap to get a steady water flow.
2. Check the LCD now shows a flow rate (l/h).
306 liters per hour with correct water flow direction
3. Turn off the water by closing the tap and check the flow rate on the LCD that it is now near 0
l/h.
If step 2 or 3 was unsuccessful, please make sure you followed the installation and pipe setup
instructions correctly. You can also try to rotate the device around the pipe, in case the pipe has
been deformed.
Note that if the meter has been activated for more than 1 hour, it will instead show total water usage
in m3.
ANTI-TAMPERING
Attach optional anti-tampering sealing cover and stickers to prevent unauthorized removal of device. Do
this only after a verified installation.

WIRELESS CONNECTION
For communication the device needs to be within LoRaWAN or Wireless M-bus coverage. If there is
no existing coverage, you can purchase a generic LoRaWAN gateway of your choice, compatible with
The Things Network (TTN).
The CubicMeter communicates using 868
MHz radio frequency which allows the meter
to be read and controlled remotely using
LoRaWAN networks.
To activate LoRaWAN for remote data
collection and visualization through our cloud
services, create an account on the Quandify
portal https://portal.quandify.com and
register your device(s). You will then also be
able to integrate the data into your own
application using our API,
https://quandify.com/api.
The CubicMeter also communicates with the
open wireless M-Bus standard using 868 MHz
mode C1, format A and security mode 5. To
receive the individual meter encryption key,
please fill in the form here:

LEAK
Possible medium leakage detected.
BURST
Possible large leakage detected.
REVERSE
Water is flowing through the meter in the wrong direction.
NO SENSING
Unable to detect water. May be due to the pipe not being filled with water, or a
loosely installed meter. Flow is not measured.

Indicates a faulty metering device, or shows a warning together with an
error/warning code.
Indicates successful radio transmissions. A single dot indicates a faulty radio
module.
Low battery, less than 180 days remaining.
The units perform an LCD check every 5 minutes where all segments are blank for 1s and then all
segments displayed for 1s as a visual verification of the LCD screen’s full functionality.
The following information is then displayed in the following order, 1s per item:
●Firmware version number
●Firmware CRC32 checksum in hexadecimal format
●Current pipe temperature in °C
●Selected pipe setting type
●Event/changelog counter
●If applicable, the last error code logged

https://quandify.com/product-documents/cubicmeter/error-codes.pdf.
If a unit is faulty, please contact your authorized distributor for further assistance. All service,
including battery replacement must be performed by an authorized Quandify service center.
Some configuration options can be performed via the meter’s built-in optical eye or LoRaWAN by
authorized personnel.
If external parts need to be replaced, such as pipe clamps and covers, only original manufacturer
spare parts should be used. Replacements should only be done by authorized personnel.
To uninstall a meter from a pipe, use a screwdriver to bend away the two tamper-seal covers until it
breaks and can be removed. Use pliers to cut the two metal fastening clamps around the pipe. The
meter can then be removed.
