Yjmf-440 series Mass flowmeter It is an advanced intelligent precision mass flow measurement instrument for measuring the mass flow and total volume of medium, volume flow and total volume, density, temperature, concentration of solution and respective concentration of two kinds of liquid mixed evenly.
Yjmf-440 series Mass flowmeter Application range:
Mass flowmeter is widely used in petrochemical, chemical, metallurgy, tobacco and other industries.
Yjmf-440 series Mass flowmeter Measurement principle:
Mass flowmeter generally refers to the flowmeter which can directly measure the mass flow reading. It refers to the flowmeter based on Coriolis principle.
Mass flow = density × flow rate × flow area（ M= ρν A ）When the density ρ in the formula is measured by the flowmeter itself, the flowmeter can be called mass flowmeter.
Mass flowmeter can be divided into direct type and indirect type
The working principle of the direct formula is often related to the mass (density) of the medium, that is, the signal proportional to ρ ν can be measured directly. At present, there are many direct mass flow meters in use: the mass flowmeter based on Coriolis principle and the thermal flowmeter based on the principle of heat exchange between fluid and solid. The former can only be used for liquid medium measurement, while the latter is mostly used for gas medium measurement.
The indirect formula is to measure the density of the medium while measuring the flow rate, or the temperature and pressure of the medium, and obtain the density of the medium through calculation, and deduce the mass flow rate from the density, velocity and flow area.
It should be specially pointed out that: in the process of measurement, when the medium density value is obtained and calculated, there will be time asynchrony or discontinuous operation, so the mass flow rate obtained is only the average value for a period of time, which is often not suitable for instantaneous flow rate. Therefore, not all flowmeters or flow measurement systems based on this principle can be called mass flowmeter.
