Product Usage Instructions
Introduction
The CubicMeter is an easy-to-install water flow meter and leakage detector designed to alert users about water leaks, measure water volume and temperature, and increase awareness about water usage. It is suitable for use with both plastic and copper pipes.
Package Contents
- 1x CubicMeter LTCM02-X
- 2x small stainless steel pipe clamps
- 2x large stainless steel pipe clamps
- 2x tamper-seal covers
- 2x tamper-seal stickers
- 1x remove to activate sticker
Installation Guide
The CubicMeter can be mounted on the property inlet pipe before it splits to different outlets like kitchens, showers, or bathrooms.
Follow these steps for proper installation:
- Ensure the pipe is clean, undamaged, free from corrosion, and free from paint.
- If the pipe surface is corroded or painted, smooth it before mounting the CubicMeter.
- For best performance, install the CubicMeter with adequate space before and after pipe bends to prevent flow turbulence.
- Follow the specified distance requirements for upstream and downstream distances based on the pipe type and outer diameter.
- Avoid using plastic zip-ties for installation as they can affect metering accuracy.
- Tighten the screws using a screwdriver to the specified torque after placing the device between the clamps.
FAQ
- Q: Can the CubicMeter be installed on any type of pipe?
- A: The CubicMeter offers models suitable for copper pipes (LTCM02-C) and plastic pipes (LTCM02-P). Ensure you select the appropriate model based on your pipe type.
- Q: How long does it take to install the CubicMeter?
- A: On average, it takes about two minutes to install the CubicMeter. However, proper preparation of the pipe surface is essential for successful installation.

CubicMeter Black (Plastic Pipes)
INSTALLATION GUIDE
- The CubicMeter can be mounted on the property inlet pipe before it splits to different outlets like kitchens, showers, or bathrooms.
- It can also be installed post-split for detailed measurements.
⚠ Ensure the pipe is ready before mounting and is:
- clean
- undamaged
- free from corrosion
- free from paint
- If the area on the copper pipe where the CubicMeter will be mounted is corroded or painted, smooth the pipe surface before mounting by removing any roughness mechanically or using a solvent.
Pipe Distance
- For best performance, install the CubicMeter with adequate space before and after pipe bends to prevent flow turbulence.
- Ensure the specified distance requirements below are met.
| Upstream Distance | X > 10x outer pipe diameter |
| Downstream Distance | Y > 5x outer pipe diameter |
Examples
| Pipe Type | Copper 15 | PAL 20 |
| Outer Diameter | 15 mm | 20 mm |
| X | Is greater than 150 mm | Is greater t mm |
| Y | Is greater than 75 mm | Is greater t mm |
Optimal Placement
The device may be rotated vertically around the pipe if needed.

Mounting
⚠ Incorrect installation affects metering accuracy; do not use plastic zip-ties.
- Loosely place the hose clamps provided around the pipe.
- Place the device between the clamps and align the brackets over the device.
- Tighten the the screws using your screwdriver to a torque of 0.4Nm.
- Remove the activation sticker. Select the pipe setting by holding the sticker over the IR-eye and removing the sticker when the correct pipe appears on the display.
- Verify on the display that the device accurately reports the flow by turning on the water flow for at least 60 seconds.
- If the 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.
Remounting
- The ultrasonic interface of the CubicMeter will adapt to the geometry of the pipe. If the device is remounted on a different pipe diameter, the performance of the device cannot be guaranteed.
- This is especially critical when moving the device from a smaller to a bigger pipe diameter.
FUNCTIONAL WATER FLOW TEST
- When the proper pipe has been selected, open any water tap to get a steady water flow.
- Check that the LCD now shows a flow rate (l/h).
- 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 steps 2 or 3 were 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: If the meter has been activated for more than 1 hour, it will instead show total water usage in m3.
ANTI-TAMPERING
Attach the anti-tampering cover and stickers after installation is complete and tested to prevent unauthorized removal.
READING THE DISPLAY
All units conduct an LCD check every 5 minutes
- First, all segments will disappear for 1 second followed by displaying all segments for 1 second. This is to verify the screen’s functionality.
- The following information is then displayed in the following order, 1 second per item.
- Firmware version number
- Firmware CRC32 checksum in hexadecimal format Current pipe temperature in °C
- Selected pipe setting type
- Event/change log counter
- If applicable, the last error code logged
