INNOVATION: SONICO^® NANO

The sonico^® NANO flow meter, based on GWF’s 4D^® technology, sets a new benchmark for supply accuracy with a precision of R1000 and exceptional robustness, covering sizes from DN15 to DN40. Designed for up to 20 years of field operation, the sonico^®NANO detects even the smallest leakages and helps prevent network contamination. Its high installation flexibility, combined with an integrated LoRa/wMBus dual-mode, reduces installation costs and enables seamless integration into modern systems.

SONICO^® NANO:IN DETAIL

- Network Performance and Reliability
  The sonico® NANO delivers precise measurement up to R1000, even under rapidly changing flow conditions and challenging installation environments. It detects even the smallest leaks or pipe bursts, helping to minimize water loss and optimize overall network performance.
- Durability by Design
  The sonico^® NANO features secure data storage with an internal memory for up to 4,000 data points and encrypted NFC and wireless communication interfaces to prevent tampering. Carefully selected materials and a design tailored for utility applications enable installation in demanding environments, reducing total cost of ownership and lowering the CO₂ footprint.
- Network Efficiency and Risk Reduction
  Its unrestricted flow channel design reduces pressure losses in the network, lowering pump energy costs. Additionally, it minimizes contamination risks by monitoring water temperature and issuing alerts in the event of reverse flow.
- Seamless Network Integration
  User-friendly data interfaces include an open API for direct integration into custom data management systems. High integration flexibility is ensured by automatic flow direction detection and dual-mode compatibility for both fixed network (FixNet) and drive-by reading systems.
- Flexible Commissioning
  The GWF INFINIO backend system, in combination with the GWF LIFE app, ensures secure key management and supports seamless, on-site network integration.
- One Technology – Universally Applicable
  The sonico^® technology supports all meter sizes from DN15 to DN40 and meets the full range of metering point requirements. It is designed for simplified inventory management and enables innovative installation practices.

SONICO^® EDGESimply brilliant – new 4D-technology^®

SONICO^® EDGE was developed for highly precise flow measurement of drinking, industrial and service water. The product concept is modular and flexible in terms of the overall mechanical design and its communication. SONICO^® EDGE is equipped with the latest GWF-4D technology^®.

SONICO^® EDGE:IN DETAIL

- Robustness through design
  Robustness through well-chosen materials and a sophisticated mechanical design prevents manipulation by external influencing factors such as changing temperatures.
- Durability through design
  A clean and straight measuring tube without cavities ensures minimised pressure loss as well as a long service life and measuring stability.
- Measurement accuracy with 4D-Technology^®
  Highest accuracy and reliability over the entire flow profile, detecting flows as low as 5 l/h and as high as 90 m3/h (DN50), results in a state-of-the-art dynamic measuring range.
- Immediately ready for use
  Easy installation and future-proof connectivity with modular, field-replaceable communication modules, guarantee integration into any communication environment and fast commissioning.
- Highest adaptivity
  The system can also be used in difficult conditions or without straight lines.
- One technology – suitable for everything
  SONICO^® technology is suitable for all meter sizes from DN50 to DN300 and all metering point requirements. It is suitable for simplified inventory management and innovative installation procedures.

TEST BENCHES FOR PRODUCT DEVELOPMENT AND PRODUCTION

GWF has a long-standing tradition of efficient and high-quality manufacturing in Switzerland. Since 1899, we have been producing gas and water meters at our headquarters in Lucerne. For the production of the sonico® product family, GWF has invested in world-leading test benches. We invite you to experience our state-of-the-art production lines and our cutting-edge flow measurement test center in Lucerne.

4D-TECHNOLOGy^®Our Cutting-Edge Technology

In recent years, GWF’s team of experts has developed a range of patents and patent applications, culminating in the unique GWF 4D^® technology.

Based on time-reverse acoustics, GWF has developed a unique methodology for processing and correcting ultrasonic signals. The signal structure operates in “slices,” capturing the entire flow channel. Instead of relying on cumbersome and sensitive correction tables, GWF uses proprietary correction algorithms based on the physical flow profile. This approach enhances measurement stability and repeatability, even under challenging conditions.

The implementation of 4D^® technology results in optimized signal generation and post-processing of measurement data. In addition, the patented method applied maximizes the signal-to-noise ratio on the receiver side, ensuring high performance.

The unique approach to transducer handling and product integration ensures long-term product stability. The overall mechanical design is also pioneering: the sonico^® series is engineered for a service life of more than 20 years. Its straight, empty-pipe design—free of cavities and equipped with dry transducers—offers clear advantages for all water types and installation conditions. Finally, the selection of materials for housings, coatings, and other mechanical components meets the highest quality standards.

GWF has extensive experience in data communication and the integration of devices into systems for billing, network management, and process control. Rapidly evolving standards, protocols, and modules demand the highest level of flexibility. GWF products are fully modular and offer open and flexible interfaces for seamless system integration.

ENCODER TECHNOLOGY:Our competence – your advantage

For gas as well as for water measurements, the GWFcoder® system plays out its advantages to the full. To ensure the reliability of the encoder system, GWF relies on technologies such as LEDs and high-performance microprocessors of the latest generation.

GWFcoder^®:IN DETAIL

Successful worldwide for over 20 years
The patented GWFcoder® technology has been successfully used worldwide for over 20 years and is continuously adapted to the latest market requirements. In this way, the measuring system always remains backwards compatible and facilitates integration into smart metering systems.
The user benefits from several advantages such as optoelectronic readout at the speed of light, absolute mechanical totaliser reading, “Plug & Play” functionality, maintenance-free operation (no battery) and standardised interfaces. GWFcoder® totalizers thus ideally combine the advantages of mechanical and electronic totalizers, which has made the GWFcoder® successful worldwide.
Encoder Schnittstelle für alle Anforderungen
Responsibility and respect for future generations require us to use our natural resources sustainably. GWF makes an important contribution to this by developing and implementing smart metering solutions. We offer forward-looking smart metering system solutions with high-precision measuring devices and thus facilitate sustainable energy use.
Standardised interfaces as well as the “Plug & Play” functionality enable a simple and convenient connection to various readout systems up to the billing system.
