Today's high tech world has produced some of the most accurate measuring tools in industry and commerce. The mass flow meteris often equipped with a coriolis flow arrangement that uses the Coriolis Effect on the fluid masses in the tubes arranged in parallel among sensors that are calibrated to measure the amount of fluid going through the tubes in relative to the vibrations they make.
The Coriolis Effect and Fluid Flow
In these flow meters, and mass flow that goes through the tubes will generate coriolis forces. Generally speaking corilis forces are present during events where mass moves in a radial pattern or when considered in an uniformly rotating frame of reference. This coriolis force inside the parallel tubes of the meter will cause the vibrations that are used in the measurement of the flow. The amounts of vibrations are directly related to the amount of mass flowing through the system and as such, this will produce an accurate measurement. Flow meters for water systems can often be built so that larger amounts of water will get through, but will still be measured accurately.
Calibration and Automation
Because the most important readings made by a mass flow meter is dependent on the vibration of a tube, ensuring that the readouts are calibrated to the correct levels are essential for the accuracy of the device. Changes in temperature and pressure will cause the rigidity of the tubes to change and this will also cause the current calibration to be inaccurate. Because of this an automated system that will take into account the items that will cause changes to the calibration factors of the meter is the most effective solution as manual calibrations will insufficient. Gas flow meters in large industries and distribution centers are often equipped with redundant systems that will help ensure that any errors caused by inaccurate calibration will be easily detected and corrected.
Measuring Units and Parameters
The mass flow meter is different from other common flow meters used in the market as it measures the mass and not the volume of a fluid that goes through the devices.The easiest example of this is the units used in readouts from the device itself. A mass flow meter will show results in mass per unit time like kilograms per second instead volume per unit time like cubic meters per second. This is important especially in applications like gas and air flow meters where the mass instead of the volume is the more important measure to accurately gauge the amount of the gas in the system.
By understanding the sensitivity and technical aspects behind Mass Flow Meter, companies can better deploy them in their facilities and projects. It is always best to contact the supplier of the meters that will be used to ensure that they will be the right kind of device to use and that they will perform their task reliably.
