APPLICATION
The ultrasonic water meter QALCOSONIC W1 BRASS is designed for precise measurement of cold and hot water consumption in households, apartment buildings, and commercial premises.
This version features a durable brass body, developed to address axiality and installation challenges where additional mechanical robustness is required. It is offered in both lead-free and leaded brass options. The BRASS version is not a replacement for the composite-body meters but rather an additional solution for applications demanding enhanced mechanical performance.
- Static water flow measurement method, no moving parts
- High accuracy and long-term stability
- Resistant to deviations caused by sand, suspended particles, or air pockets
- 9-digit multi-line LCD showing total volume and instantaneous flow rate
- Sensitive and accurate even at very low flow rates (down to 1 l/h)
- Optional pressure sensor integration for advanced monitoring (COMING SOON)
- Maintenance-free design, battery life up to 16 years*
- Installation possible in any position – vertical, horizontal, or diagonal
AMR READY
- wM-Bus 868 MHz OMS T1
- LoRaWAN (EU863–870, IN865–867)
- NB-IoT (CoAP)
- NFC
NFC and optical interfaces integrated in the top panel allow easy data reading and parameterisation.
APPROVALS
- MID (2014/32/EU)
- LoRaWAN compliance certificate
- OMS compliance certificate
- WRAS (UK)
- ACS (France)
- ICIM (Italy)
- KIWA (Netherlands)
- OIML
TECHNICAL FEATURES
- Temperature class: T30, T50, T70, T30/90, T90
- Nominal flow: 1.6 / 2.5 / 4.0 m³/h
- Wide measurement range: Q3/Q1 = 160 / 250 / 400 / 500 / 800 (optional)
- Nominal pressure: PN16
- Protection class: IP68
- Environment class: E2/M1
- Installation: any position
- Data logging: hourly, daily, and monthly values stored internally
- Flow direction indication and multiple alarm functions (leakage, burst, backflow, empty pipe, low temperature, etc.)
- Measurement units: m³ – m³/h
KEY ADVANTAGES
- Enhanced axial precision with robust brass construction
- Optional pressure sensor for smarter water network diagnostics (COMING SOON)
- Long-term accuracy and durability, even in challenging environments
- Seamless AMR connectivity supporting wM-Bus, LoRaWAN, NB-IoT, and NFC
