For us, tradition and innovation are not a contradiction in terms, and so we are consistently developing into an innovative system and service provider in the measurement of valuable resources. We work directly with electricity, gas, water and heat suppliers and are also active in the field of building technology and building automation. With our team of specialists we support our customers in the tasks of consumption data acquisition, data communication and data processing and offer system solutions.
Products & services
sonico® EDGE DN50 – DN300
Sonico® EDGE has been developed for highly accurate flow measurement of potable, industrial and service water. The product concept is modular and flexible in terms of overall mechanical design and communication. Sonico® EDGE is equipped with the latest GWF 4D technology® . To manufacture the sonico® product line, GWF invested in a world-leading production test bench ‘LUZ1’. The test bench was installed in early 2018 as one of the most accurate production equipments in the world. Currently, the overall production and quality system is put in place to manufacture the sonico® product line for applications in the commercial and industrial domain.
Acoustic Flow Measurement
GWF is at the forefront of innovative flow technologies, products and solutions. We measure anywhere: in rivers, channels, and partially filled or pressurized pipes. Ultrasound propagates through fluid media as pressure waves. Our instruments are able to convert information gained from measuring the behaviour of these waves into flow speed. There are two main measurement principles on which our instruments are based. Applying the Transit Time technique, we measure the time of flight with and against flow direction. When using the Pulse-Doppler effect, our instruments record the change of the signal frequency reflected by a particle in the flow. We encourage you to discover our products and services around Acoustic Flow Measurement on this website or in our brochure. Please contact us – we look forward to exchanging ideas on the challenges of water management, and to working with you to make your measurement a success.
Multical® 603
The future-proof heat and cooling meter with full next-generation flexibility and quality. Flexibility and scalability are key to ensuring that today’s metering solution is equipped to handle tomorrow’s challenges. The new MULTICAL® 603, with its efficient dimensions, comes in a modern design and serves as a versatile calculator. Whether used as a heat meter, cooling meter, or combined heat/cooling meter, it enables you to easily upgrade or replace your measuring devices. This ensures you are prepared for new possibilities and future requirements.
MTKcoder® MP compact
The well-established GWFcoder®-system reads the absolute mechanical register value precisely and reliably and provides the data through standardized interfaces. The number wheels with three various long, asymmetrically arranged slots are being scanned through light pipes which are connected to five light emitting diodes (LED).
Electronic volume converter EK280
The EK280 electronic volume converter can be used with all gas meters and also records the original meter readings with the absolute encoder counter. Integrated pressure and temperature sensors calculate the standard volume using the operating volume and the state and compressibility numbers. Both battery and mains operation are possible. The integrated, event-driven data memory supports three independent archive functions.
BGZcoder® MP AE5
Diaphragm gas meter with electronically readable mechanical roller register and multi-protocol interface SCR (IEC), M-Bus and ECO YOUR BENEFITS Mechanical roller register with up to 1-liter resolution: Efficient consumption monitoring in smart metering installations. Modular design due to the multi-protocol interface: Investment security for future applications. No battery limiting the service life: Maintenance-free. No parameterisation effort for device identification and meter alignment when connecting to a reading system: Simple and fast on-site installation. Separate sealing of register and communication module: Communication modules can be retrofitted in the field without loss of the meter’s verification validity.
Singlejet meter UNICOcoder® MP
Singlejet consumption meter with M-Bus interface EN 13757-2 for warm water up to 90 °C
Smart Water Meter sonico® NANO
The sonico® NANO flow meter, based on GWF 4D® Technology, sets a new benchmark for utility-grade accuracy with R1000 precision and robustness, covering sizes from DN15 to DN40. Designed for up to 20 years of field use, the sonico® NANO detects even the smallest leak flows and helps prevent grid contamination. Its high installation flexibility, combined with the integrated LoRa/wMBus dual mode, reduces installation costs and ensures seamless integration into
Drive-by readout software UDRIVE
UDRIVE is a digital product developed by GWF AG that aims to offer an easy and seamless solution for collecting the readouts of your meters. This multi-energy solution is working with a wide range of meters that are Wireless M-Bus. UDRIVE is perfectly adapted for the billing purposes of municipalities or energy providers and is able to work with many ERP system. This application is working together with the INFINIO cloud platform.
Ductus - For fully filled pipes
Ductus – for pressurized pipe applications Extreme low flow measurement accuracy in combination with industry leading dynamic range, maximize flow capture. Your large diameter flow measurement and custody transfer billing will become much more reliable. In wastewater treatment plants, Ductus will help you to capture low velocities and will optimize your management of capacity needs, biological processes and sludge returns. In hydropower applications, Ductus is used to implement turbine efficiency monitoring.
