What is the mass flow meter?
Material flow meter is a device used to measure the flow of fluid or gas passing through the tube at a fixed time. The material flow in this sense concerns weight and not the volume of substance. The mass flow measurement is used in various scientific and industrial applications and is achieved by one of the two common types of mass flow meters: an inertial or coriolis meter and a thermal weight meter.
The mass flow that is not confused on the volume flow is a measurement of liquid or gas mass behind a fixed point in a specific time frame. The standard unit of measure for the mass flow is pounds per second or kilograms per second rather than gallons or liters per second. These measurements are performed with one of the two different types of weight flow meters. The first uses a natural phenomenon known as the effect of Coriolis to measure the mass flow. The second type uses the principles of thermal transmission.
koriolis or flow meter of inertia uses fluids flowing through the arrangement of tubes that JThey are subjected to an induced semicircular vibration force. The resulting coriolis effect leads to oscillation in different parts of the tube arrangement that moves from the phase. The range of this phase shift is directly proportional to the mass flow of the fluid in the tube. The sensors placed on the tube measure the amplitude, frequency and phase shift of these oscillations. The mass flow of the fluid is then extrapolated from the sensor values.
The second common type of mass flow meter, thermal variant, uses the principle of heat transfer under controlled conditions to calculate flow rates. The gas or liquid passes through the tube where the heat sources are exposed. When fluid molecules pass through the heat source, they absorb thermal energy, thereby cooling the source. The greater the weight of the fluid passing through the heat source, the greater the cooling effect.
The speed of molecular energy transfer is known constant and the cooling range is a measurable variable. These two factors are used to calculate the number of molecules that in the given ObdoWhite passed the heat source. From this result, the exact mass flow is calculated. The detailed thermal profile of the fluid and its characteristics of the flow can also be learned from the results of thermal transmission.
