Abstract:
A Coriolis flowmeter which vibrates in a mode of three-forked plate vibration comprising a straight conduit through which a fluid to be measured flows and which has a predetermined resonance frequency and a sensor attached thereto, and two counter straight rods that have the same resonance frequency as the resonance frequency of the straight rod conduit and are aligned on both sides of the conduit in parallel space, one end of the conduit and each one end of the counter rods being fixed to a common support block and another end of the conduit and each another end of the counter rods being fixed to another common support block, in which each of the conduit and counter rods has a vibration generator attached thereto for generating vibrations in such manner that the conduit and the counter rods vibrate in opposite phase, and both support blocks are fixed onto a rigid substrate.
