Field of application
State-of-the-art technology for maximum measurement accuracy: The FLOWSIC550 ultrasonic compact gas flowmeter ensures highly accurate billing of low volume flows in high-pressure networks – a perfect complement to the FLOWSIC500. It is overload-proof, accurate and is monitored by an intelligent diagnostics system. FLOWSIC550 can be easily integrated into existing measuring stations. When used in transfer and measuring stations, FLOWSIC550 ensures a continuous and blockage-free gas supply.
Gas Measurement of low volume applications at high pressures
Custody transfer: gas distribution, storage, and transmission systems
Town border stations and city gate stations
Key Benefits
- Ultimate measurement certainty and safety of continuous gas supply
- Simple installation, replacement of turbine gas meters
- Reduction of installation costs due to integrated volume correction
- Easy Commissioning and data reading via FLOWgateTM (App and PC)
- Minimal operating costs due to being nearly maintenance-free
- Reliable even when the gas flow fluctuates (on/off applications)
- Self-sufficient operation possible
