High-pressure gas flow meter for natural gas distribution
 
The cutting-edge technology for natural gas measurement: The new FLOWSIC550 ultrasonic compact gas meter from Endress+Hauser ensures highly accurate metering for low volumes at high pressures in gas distribution - a perfect addition to FLOWSIC500. In the absence of mechanical moving parts, the FLOWSIC550 is a robust, fail-safe and low-maintenance device, allowing for a significant reduction in operating costs. It is overload-proof, accurate and is monitored by an intelligent diagnostics system.

FLOWSIC550 can easily be integrated into existing measuring stations. The FLOWSIC550 operates either in an energy self-sufficient configuration or in network operation. When utilized in transfer and measuring stations, FLOWSIC550 ensures a continuous and blockage-free gas supply.
Features
  • Rugged and time-proven ultrasound technology
  • Diagnostics and permanent operational self-monitoring
  • Durable and reliable without moving parts
  • Compact meter installations
  • Integrated volume correction
  • Battery or intrinsically safe power supply
  • Bluetooth Low Energy (BLE)
Benefits
  • Ultimate measurement certainty and safety of continuous gas supply
  • Simple installation and replacement of turbine gas meters
  • Reduction of installation costs due to integrated volume correction
  • Easy Commissioning and data reading via FLOWgateTM (PC and App)
  • Minimal operating costs due to being nearly maintenance-free
  • Reliable even when the gas flow fluctuates (on/off applications)
  • Self-sufficient operation possible
