Heating and water meters
1. Thermal and Water Meters
Thermal meters and water meters are installed directly on a pipe.
A water meter measures the flow rate (m³) circulating in the pipe.
A thermal meter measures the flow rate as well as the inlet and outlet temperatures of the circuit, which it then converts into energy (kWh).
The nominal size (DN) of a meter is determined by its measuring chamber and not by its connection size.
Ex. A DN20 meter has a thread on the meter of 1", which means the fitting screwed onto it for the pipe is 3/4".

Meters of the same DN also have the same length.
DN Comparison Table
Nominal size | Meter thread | Length | Flow rate | Screwed fitting |
DN 15 | 3/4" | 110 mm | 2.5 m³/h | 1/2" |
DN 20 | 1" | 130 mm | 4 m³/h | 3/4" |
DN 25 | 1 1/4" | 260 mm | 6.3 m³/h | 1" |
DN 32 | 1 1/2" | 260 mm | 10 m³/h | 1 1/4" |
DN 40 | 2" | 300 mm | 16 m³/h | 1 1/2" |
DN 50 | 2 1/2" | 300 mm | 25 m³/h | 2" |
To communicate with the Climkit Gateway, all meters must be equipped with a wired MBus communication module.
Here are some examples of standard heating and water meters:
2. Thermal Meters for Heat or Cooling
Integra Amtron S3U Meter
- Ultrasonic (heat and cooling) battery-powered (10-year lifespan)
- No wear or other issues like mechanical versions.
- Primarily used for apartments.
- Normally used in DN15 or DN20. Also available in DN25.

Models for Heat (DN15 and DN20)
- AMTRON S3U_15_1.5_110_G3/4_BM_h – 97154
- AMTRON S3U_20_2.5_130_G1_BM_h - 97155
Models for Heat and Cooling (DN15 and DN20)
These meters have two indexes (kWh heat and kWh cooling).
They increment respectively based on whether the temperature difference between the two sensors is positive or negative.
- AMTRON S3U_15_1.5_110_G3/4_BM_hc – 97174
- AMTRON S3U_20_2.5_130_G1_BM_hc - 97175
Models for Cooling (DN15 and DN20)
- AMTRON S3U_15_1.5_110_G3/4_BM_c – 97190
- AMTRON S3U_20_2.5_130_G1_BM_c - 97191
DN25 or higher
For DN32 or higher, use the Sonic D.
The Sonic D is powered by 230V (no battery).
Generally used for measurement at the boiler outlet, in CAD substations, and for domestic hot water production.

3. Hot Water (Domestic Hot Water) or Cold Water (Cold Water) Meters
DHW and cold water meters are identical.
Surface-mounted water meter (DN15 and DN20)
- SAPHIR Modularis ETW 15 1.5_110_G3/4 BM – 95148
- SAPHIR Modularis ETW 20 2.5_130_G1 BM – 95149

Coax water meter for flush-mounted installation
- SAPHIR Modularis MTW IE koax 1.5 BM – 95142

Available accessories: extension pipe (if too far from the wall) and decorative ring

Example of mounting system for flush-mounted meter:

Datasheet: Saphir Modularis meter
Mounting Guide: Saphir Modularis surface-mounted
Mounting Guide: Saphir Modularis Koax flush-mounted
DN25 or higher water meter
For DN25 or higher, use the PMK-aquabasic
Ideal for high flow rates such as irrigation.
Caution: 3 types depending on mounting:
- Horizontal
- Vertical descending
- Vertical ascending
Supplied with screwed connection kit and MBus communication module.

4. MBus Converter
The MBus-RS485 converter allows connecting MBus meters to the Climkit Gateway.
