Advantages and disadvantages of Coriolis mass flowmeter

After the Coriolis mass flowmeter was put into market, although the price was high, it replaced the some applications of volume flowmeter, the velocity flowmeter, the differential pressure (DP flow meter) flowmeter, etc. with its irreplaceable advantages, and stably occupied the market with its excellent performance.
Advantage of Coriolis meter
  • It can direct take measurement of mass flow with high measurement accuracy.
  • It has a wide range of measurable fluids, including high viscosity fluids, liquid-solid two-phase fluids, liquid-gas two-phase fluids containing trace gases, and medium and high pressure gases of sufficient density.
  • The vortex flow and non-uniform flow velocity distribution caused by the upstream and downstream pipelines have no influence on the performance of the flow sensor. Generally, it is not required straight pipe lines when installing the sensor.
  • The change in fluid viscosity has no significant effect on the measured value.
  • The change in fluid density has little effect on the measured value.
  • There are multiple outputs, which can simultaneously output instantaneous mass flow or volume flow, fluid density, fluid temperature and other signals. It also has several digital input and output ports, and some models can realize batch control functions.
  • Bidirectional flow measurement
  • It can take measurement of high viscosity fluids, such as crude oil, heavy oil, residual oil and other liquids with higher viscosity. Previously, volumetric flowmeters, target flowmeters, etc. were used to measure flow. Now, Coriolis mass flowmeters are used, with good reliability and accurate measurement result.

Disadvantage of Coriolis flow meter

  • Poor zero stability which affects the flow meter accuracy.
  • It cannot be used to measure fluids with lower density, such as low pressure or low density gas.
  • Slightly higher gas content in the liquid may cause a significant increase in measurement error.
  • It is sensitive to external vibration interference.
  • It cannot be used for larger diameters. Currently max size we can make is 8 inch Coriolis flow meter.
  • The pressure loss is large, especially when measuring a liquid with a high saturated vapor pressure, the pressure loss may cause vaporization of the liquid, and cavitation occurs.
