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
Highest measurement certainty and safety of continuous gas supply
Reduction of installation costs due to integrated flow conversion
Simple installation, compatible with conventional technologies (turbine and rotary
displacement meters)
Minimal operating costs due to being nearly maintenance-free
Simplified recalibration due to straightforward cartridge exchange
Reliable under dynamic load changes
Self-sufficient operation
