Data storage at the shipment from the factory●●■ Measurement Principle and Construction

Transmitter

The mass flowmeter operates on the principle of Coriolis force. A pair of flow tubes fixed att
both ends is excited by an electromagnetic oscillator to maintain oscillation at resonantt
frequency. A twist of these flow tubes takes place in proportion to the mass flowrate of theeprocess fluid, which is sensed by the right-hand and left-hand electromagnetic pickoffs. Thee

Flow Tubetransmitter then sends its output as a mass flow signal.
