State-of-the-art technology for maximum measurement accuracy: The new FLOWSIC550 ultrasonic compact gas flowmeter ensures highly accurate billing of low volume flows in high-pressure networks – a perfect complement to the FLOWSIC500. It is overload-proof, accurate and is monitored by an intelligent diagnostics system. FLOWSIC550 can be easily integrated into existing measuring stations. When used in transfer and measuring stations, FLOWSIC550 ensures a continuous and blockage-free gas supply.

Minimal operating costs due to being nearly maintenance-free
Reliable even when the gas flow fluctuates (on/off applications)
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.
