Coriolis mass flow meters measure the mass
flow of liquids and gases directly in almost any application without special
calibration. Multi-functional Coriolis mass flowmeters provide reliable,
accurate mass flow, volumetric flow, temperature, density and concentration
The shortcomings and advantages of the mass
flow meter are listed below for the user's reference.
Advantage of Coriolis Flowmeter
The measured values are not sensitive to fluid viscosity, and the change in fluid density has little effect on the measured value. Therefore, it is possible to measure liquids with high viscosity, such as asphalt, syrup, and the like.
Installation above, there is no requirement for upstream and downstream straight pipe sections.
The Coriolis mass flow meter directly measures mass flow and has high measurement accuracy.
It can measure a wide range of fluids, including various liquids of high viscosity liquids, slurries containing solids, liquids containing trace gases, and medium and high pressure gases of sufficient density.
The measuring tube has small vibration amplitude and can be regarded as a non-moving member, and the measuring tube has no obstruction and movable parts. Therefore, the life span is relatively long.
It is possible to measure as much as a variety of data, such as the simultaneous measurement of density, and thereby derive the concentration of the solute in the measurement solution.
Disadvantage of Coriolis Meter
Mass flowmeters have large
pressure losses, and some Coriolis mass flowmeters are even 100% larger than
Coriolis mass flowmeters are
sensitive to external vibration disturbances. To prevent the effects of
pipeline vibrations, most models of Coriolis mass flowmeters have higher
requirements for installation and fixing of flow sensors.
Mass flow meters cannot be used
for larger diameters and are currently limited to less than 200mm.
The zero-point instability of
the Coriolis mass flowmeter creates a zero drift, which further affects its
Coriolis mass flow meters
cannot be used to measure low-density media and low-pressure gases; the
presence of gas in a liquid above a certain limit (varies by model) can
significantly affect the measured value. Low-density gases generally use a
thermal gas flow meter.
Wear and corrosion of the inner
wall of the measuring tube or deposition of scale can affect the measurement
The Coriolis mass flow meter is
heavy and bulky, resulting in a significant increase in freight costs.
Especially when used for exporting goods, the cost of international shipping is
Mass flow meters are expensive;
especially those made in Europe, America, and Japan, and are more expensive.
At present, Chinese manufacturers have
mastered the technology of Coriolis mass flowmeters, and can produce mass
flowmeters with stable performance, low price, short delivery time and powerful
functions. Welcome to consult the price Coriolis meter from Silver Automation Instruments.
