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.
