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.

Schluchseewerk AG wanted to record and optimize the efficiency of its turbines at the pumped storage plant in Wehr. Endress+Hauser offers the optimum solution with its ultrasonic clamp-on flowmeter.
GPsol, together with Endress+Hauser, developed a system that individually measures each component of extraction wells and provides as much information as possible about the current flow.
