Mass flow meter Coriolis

Coriolis mass flow meter (also known as Coriolis mass flow meter) is a kind of mass flow meter with high measurement accuracy. The principle is based on Newton’s second law when the fluid flows in the vibrating tube, will produce Coriolis force proportional to the mass flow rate. When there is no fluid flow through, the vibrating tube does not produce distortion, vibration tube on both sides of the electromagnetic signal detector detected signal is in phase; when there is a fluid through, the vibrating tube in the torque under the action of distortion, there will be a phase difference between the two detectors. The transmitter measures the lag time between the left and right detected signals, and this time difference is multiplied by the flow calibration coefficient to determine the mass flow rate. Features: ・High precision ・Measurement of mass flow rate is possible ・No need for a straight pipe ・High response speed ・Can measure high viscosity liquids ・Can measure density Applications: In petrochemical production units have also been widely used, such as flowing through the process pipeline in a variety of slurry, non-Newtonian fluids, high-viscosity fluids, liquids containing traces of gases, suspensions, separate media fluid, with sufficient density of high-pressure gases, etc. are able to adequately meet the petrochemical production units on the measurement of the mass flow meter requirements. But can not be used to measure the pipeline flowing through the density is too low, such as low-pressure gases and other media, when the process pipeline fluid medium containing gas, in the gas content exceeds a certain value,
