Your benefits
- GWF 4D technology® measures best in class high and low flows (DN50: Start flow down to 5 l/h and up to > 90 m3/h):
Immediate detection of leakages and network errors, suitable for fire flow - Maximum installation flexibility:
Reliable measurements over the full flow range, independent of installation conditions. No straight runs needed even with 90° elbows, valves or pumps - Accuracy by design: GWF 4D technology® maximizes turndown ratio up to R1000:
Highest accuracy across the entire flow profile leads to a cutting edge dynamic range - Homogeneous 4D-shape measuring pipe with dry sensors and no obstacles or cavities:
Minimal pressure loss enhances high flow capability and minimizes operating costs. Dry sensors lead to increased meter life-time, reliability and dirt resistance
Applications
- Water measurement, e.g. drinking water or utility water (reservoirs, pumping stations, etc.)
- Suitable for difficult installation conditions such as placement directly before or after 90° elbows, valves or pumps
- The time-reverse acoustic measuring principle enables a new level of measuring repeatability unaffected by flow perturbations, electromagnetic or grounding interference and water conductivity

Product information
4D-shape measuring core
Due to the unique 4D-shape pipe design and the implemented GWF 4D technology®, the measurement is independent of the flow profile. Dry sensors guarantee a highly accurate and reliable measurement performance over the entire meter lifetime.
The 4D-shape measuring core allows for installation of the meter directly behind a 90° bend or a valve. This flexibility results in minimal installation costs, since no additional on-site work has to be considered.
sonico® EDGE – in Germany and Switzerland developed and produced. The patented time reverse acoustic measuring principle enables a new level of measuring repeatability unaffected by flow perturbations, electromagnetic or grounding interference and water conductivity.
Ultimate communication
The GWF 4D technology® platform supports a Near Field Communication (NFC) interface that ensure sustained connectivity during the entire product lifetime.
Maximum two of the following available communication module can be attached to the flexible NFC communication interface in parallel:
- Pulse: Pulse output (0.1 l; 1 l; 10 l; 100 l; 1000 l) configurable
- Current: 4-20 mA output configurable for uni- or bidirectional measurements.
- ECO E1 or E2: Low Power serial data interface (e.g. to connect a NB-IoT Modem)
- Modbus: Modbus RTU/ASCII protocol with extended flowmeter data

MID/OIML measuring accuracy
GWF 4D technology® offers a bidirectional turndown ratio R1000 acc. to MID/OIML and is extremely robust against changes in the flow profile caused by bends, valves or pumps. The patented time-reverse acoustic measuring principle enables a new level of measuring repeatability independent of flow conditions, electromagnetic or grounding interference and medium conductivity.
Industrial accuracy
In addition to MID/OIML calibration, GWF offers accredited industrial calibrations in accordance with ISO 17025 in the flow rate range from 0.005 m3/h to 600 m3/h.
Based on the GWF 4D technology®, an industrial calibration results in a measurement uncertainty of up to ± 0.2 % of the measured velocity ± 0.5 mm/s.
Typical pressure loss curve
The homogeneous 4D-shape measuring pipe ensures minimal pressure loss (< 0.04 bar on DN50 @ Q3), offering highest reliability at lowest operational costs.
