应用领域
The FLOWSIC500 ultrasonic flowmeter enables extremely accurate natural gas distribution measurement. It is overload-proof, accurate and is monitored by an intelligent diagnostics system. It can easily be integrated into existing measuring stations. It operates either in a self-sufficient energy configuration or in failsafe network operation with battery back-up. It complies with all pertinent standards and directives and provides the security of a continuous and blockage-free gas supply.
Natural gas distribution in transfer and measuring stations for municipal and regional gas suppliers
Measuring stations in industrial and commercial applications
Device properties:
Diagnostics and permanent operational check
Rugged and reliable due to lack of moving parts
Exchangeable cartridge
Straight inlet/outlet zone not required
Overload-proof
Optional integrated flow conversion / date registration
Battery or intrinsically safe power supply
优势
Highest measurement certainty and safety of continuous gas supply
Reduction of installation costs due to integrated flow conversion
