Smart Metering
Smart water metering with AXIOMA Qalcosonic ultrasonic meters, NB-IoT and integrated e-SIM, with no gateway or concentrator in the field.
The foundation for a new smart water management in Brazil
M2M supplies and represents in Brazil the Qalcosonic line from AXIOMA Metering, a European manufacturer of ultrasonic meters, and integrates the meters into its telemetry and management platform.
- Supply and representation of the Qalcosonic line in Brazil
- INMETRO certification conducted by M2M with LABELO
- NB-IoT connectivity with e-SIM integrated into the meter
- Application engineering, commissioning and local support.
Measurement that captures the consumption mechanical water meters miss
Static measurement
No moving parts and no wear, immune to sand, particles and air pockets.
Sensitivity at low flow rates
Starting flow from 1 l/h and dynamic range up to R 800.
Simplified installation
No straight pipe runs required (U0 D0), in any position, with IP68 protection.
Bidirectional metering
Separate forward and reverse volumes, the basis for water balance and backflow detection.
From DN15 to DN50, with valve on DN15 and DN20
Qalcosonic W1
- DN15, DN20, DN25, DN40 and DN50, without valve
- Q3 from 1.6 to 40 m³/h
- From residential micrometering to macrometering
Qalcosonic W2 with valve
- DN15 and DN20 with integrated SmartValve
- Remote cut-off and reconnection
- Automatic self-cleaning cycle
- Delinquency management without field trips
Alarms
- Leaks and bursts
- Reverse flow and empty pipe
- Tampering and low battery
- No consumption in 3, 7 or 30 days
MOU with Sabesp for 600 thousand smart meters
In January 2026, M2M and AXIOMA signed an MOU with Sabesp to supply 600 thousand smart water meters for São Paulo and São José dos Campos, in one of the largest water AMI projects in the world, with more than 4 million meters by 2029.
