Flowmeter uses Coriolis force in measurement The Sitrans FC430 flowmeter from Siemens AG is capable of measuring liquids and gases using the Coriolis principle. Flows can be measured with a precision of 0.1%, and different sensor sizes are available to address various applications. The technical solution of state-of-the-art flow devices based on the Coriolis force uses two vibrating tubes. The tubes are forced to vibrate using a magnetic driver, which is controlled by an electronic driver circuit and the appropriate software. Two electromagnetic transducers measure the velocity of the tube deflection between input and output. The driver and the transducers are part of a closed-loop control
