FLOWSIC600
Ultrasonic Gas Flowmeter
The FLOWSIC600 measures the actual volumetric flow rate, actual accumulated volume, gas velocity or velocity of sound in gases with high measurement acuraccy over wide measuring ranges. It is ideal for flows with high dynamics.
The FLOWSIC600 2PLEX is ideal for custody transfer because of its 4-path meter for billing and the integrated 1-path meter for monitoring of internal faults.
