What are the functional features of Coriolis mass flowmeters
The Coriolis mass flowmeter (also known as the Coriolis mass flowmeter) is a type of mass flow instrument with relatively cy. high measurement accuraThe principle is based on Newton’s second law: when a fluid flows in a vibrating tube, a Coriolis force proportional to the mass flow rate will be generated.
The Coriolis mass flowmeter (also known as the Coriolis mass flowmeter) is a type of mass flow instrument with relatively cy. high measurement accuraThe principle is based on Newton’s second law: when a fluid flows in a vibrating tube, a Coriolis force proportional to the mass flow rate will be generated. When no fluid flows through, the vibrating tube does not twist, and the signals detected by the electromagnetic signal detectors on both sides of the vibrating tube are in phase. When fluid passes through, the vibrating tube will twist under the action of torque, and there will be a phase difference between the two detectors. The transmitter measures the lag time between the left and right detection signals. Multiplying this time difference by the flow calibration coefficient can determine the mass flow rate.
The Coriolis mass flowmeter has a high measurement accuracy, ensuring an accuracy of 0.1% to 0.2%. It can withstand low-temperature media, has a relatively small vibration amplitude, no moving parts, operates reliably and stably, is easy to operate and simple, has a low maintenance rate and is convenient to maintain. It can directly measure the mass flow rate of the medium and the real-time density of the fluid. It can be said to be an extremely convenient density instrument. It features integrated temperature and pressure compensation, directly outputs mass or standard square meters. The instrument is equipped with a self-checking program, making fault phenomena clear at a glance. It offers multiple outputs and can remotely transmit various data. It can be made of multiple anti-corrosion and high and low temperature resistant materials. Users can choose from optional small signal cut-off, nonlinear correction, and filtering time.
This surgical force mass flowmeter has also been widely applied in petrochemical production facilities. For instance, various slurries, non-Newtonian fluids, high-viscosity fluids, liquids containing trace amounts of gas, suspensions, single-medium fluids, and medium and high-pressure gases with sufficient density flowing through process pipelines can all fully meet the measurement requirements of mass flowmeters in petrochemical production facilities. However, it cannot be used to measure low-pressure gases and other media with too low density flowing through pipelines. When the fluid medium in the process pipeline contains gas and the gas content exceeds a certain value, it will significantly affect the measurement value of the Coriolis force mass flowmeter, resulting in inaccurate measurement results. Therefore, the Coriolis force mass flowmeter cannot be used to measure gas-liquid two-phase fluids.
The Coriolis force mass flowmeter also has relatively low requirements for on-site installation. This is because the flow velocity distribution corresponding to the Coriolis force mass flowmeter is not very sensitive. Therefore, the requirements for the upper and lower straight pipe sections during installation are not high.
