QALCOSONIC W1 (from DN25 to DN50) Datasheet

Product catalog summary

Application
The Qalcosonic W1 is an ultrasonic water meter designed for precise measurement of cold and hot water consumption in residential, commercial, and apartment settings. It uses a static method for water flow measurement, ensuring high accuracy and eliminating deviations caused by sand, suspended particles, or air pockets. The device is reliable and stable over long-term use, featuring a 9-digit multi-line LCD for total volume and instantaneous flow rate indication. It is sensitive to low flows, down to 3 l/h, and is equipped for Automatic Meter Reading (AMR) with NFC, wM-Bus, LoRa, and NB-IoT technologies.

AMR Ready
The meter supports wM-Bus at 433 MHz or 868 MHz OMS T1, LoRaWAN across various regional channel plans, and NB-IoT (CoAP). NFC and optical interfaces are integrated for data reading and parameterization.

Approvals
The Qalcosonic W1 complies with several standards and certifications, including MID (2014/32/EU), OIML R49, LoRa WAN, OMS, WRAS (UK), ACS (France), ICIM (Italy), and KIWA (the Netherlands).

Technical Features
The meter supports various temperature classes (T30, T50, T30/90, T90) and nominal flow rates (6.3 / 10 / 16 / 25 / 40 m3/h). It has a wide measurement range (Q3/Q1 = R 80 / 160 / 250 / 400 / 500 / 800) and does not require straight pipe sections for installation. It can be installed in any position and does not measure air. The device is classified under electromagnetic environment class E2 and mechanical environment class M1, with a protection class of IP68. It operates at a nominal pressure of PN16 (PN25 for flange version) and includes an internal datalogger. The device is maintenance-free with a battery life of up to 16 years, depending on communication settings.

Data Logger and Radio Interface
The internal memory stores hourly, daily, and monthly values of measured parameters. Integrated radio communication allows data reading via wM-Bus telegram, LoRaWAN, or NB-IoT.

LCD Indications and Alarms
The meter provides multiple alarms and events, including flow direction, battery level, leakage, burst, backflow, empty pipe, radio communication, warning indication, and low-temperature warnings.

Technical Data
The flow sensor supports various flow rates and dynamic ranges, with a protection class of IP68. It is suitable for both indoor and outdoor environments, with an ambient temperature range of -15°C to +70°C. The meter can be installed in any position and operates at a nominal pressure of PN16 bar (PN25 bar for flange version). The battery life varies with communication settings, up to 16 years for LoRa/wM-Bus versions and up to 13 years for NB-IoT versions.

Size & Dimensions
The meter is available in various sizes and dimensions, with nominal diameters ranging from DN25 to DN50 and corresponding connection types.
