How should I ask you questions? Through a message
I’m interested in your Coriolis flowmeters; could you provide more details?
What level of fluctuation in the drive of a mass flow meter is considered abnormal? Are its fluctuations mainly caused by gas-liquid two-phase flow and external vibrations?
Can the cumulative flow value of Emerson’s mass flow meters be decreased?
Hello, OP! Is there a large price difference between density meters and mass flow meters? Can we use a mass flow meter instead of density for the calculation?
Only discussing technology, not business prices. . . Mass flow meters have defects in measuring density; when used to measure media such as lime slurry that contain particles, they suffer severe wear and become unusable within a few months. Another type of densitometer is the fork-type densitometer, which has much greater wear resistance than Coriolis mass flow meters. . For generally clean liquids, oils, and the like, a mass flow meter can be used to measure density.
Different diameter drives vary; generally, it does not exceed 20%, and the larger the diameter, the higher this value is. But none exceed 20%. It is mainly the gas-liquid two-phase flow that causes fluctuations and enlargement. . . Hanging on the wall or getting blocked can also happen. .
It can be set through configuration. Flow direction. . Two-way metering, with cumulative reduction in the reverse direction. . . .
