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.
