    摘要: An apparatus for measuring fluid flow has a measuring device operating in accordance with the Coriolis principle. The measuring device has an oscillating conduit wherein the fluid to be measured flows through the conduit, and a sensor for sensing the movement of the conduit and generating output signals indicative of the movement. The measuring device generates a measurement signal based on the sensor signal indicative of the flow rate of fluid through the conduit. A counting device is coupled to the measuring device for receiving the measurement signal and calculating the flow rate of fluid through the conduit based on the measurement signal. An error-detecting device is coupled to the measuring device and to the counting device for comparing the measurement signal to a threshold value, and if the measurement signal exceeds the threshold value, the error-detecting device interrupts the transmission of the measurement signal to the counting device and transmits a predetermined measurement signal to the counting device.
