Description of YFM800 Hot Gas Mass Flow Meter
YFM800 series gas thermal mass flowmeter is a flowmeter based on thermal diffusion principle.That is, when the fluid flows through the heating object, the heat loss of the heating object is proportional to the flow rate of the fluid.Specifically, the sensor of the flowmeter has two standard RTD, one is used as a heat source, the other is used to measure the temperature of the fluid, the fluid flow, the temperature difference between the two is non-linear relationship with the size of the flow, the meter can convert this relationship into the linear output of the measurement flow signal.There are two design methods for flowmeter manufactured by thermal diffusion principle: one is based on thermostatic difference principle;The second is based on the constant power principle.Based on the common data model: P/ train T=A+B(Q) n. where: P -- dissipated power; T -- temperature difference between two sensors; Q -- mass flow; N -- exponential coefficient; A and B are the coefficient related to the thermal performance of the gas. Thermostatic difference principle: T remains constant, dissipated power P and fluid flow Q into an exponential function increasing relationship. Constant power principle: dissipated power constant, temperature difference delta T and the flow of fluid Q into the relationship of exponential decline function. Our company adopts the thermostatic difference method.
Features of YFM800 Hot Gas Mass Flow Meter
1. The patented platinum RTD sensor with high stability is adopted
2. True mass flowmeter without temperature and pressure
compensation.The mass flow rate or standard flow rate of the gas
can be obtained.
3. The range ratio is 500:1, which can be extended according to
user's requirement
4. Large pipe diameter and small flow can be measured, and the
minimum flow can be measured as low as 0.5Nm/S
5. No moving parts, vibration can be ignored
6. Straight pipe section is not required to be high 1-2d
7. It is independent of the temperature and pressure of the medium
8. Digital design, digital circuit measurement, accurate, easy
maintenance
9. Not sensitive to small particles such as dust.
10. Online continuous loading and unloading, easy maintenance.
