Details of Thermal Gas Mass Flow Meter :

是基于热扩散原理的流量仪表。 XY-RSL thermal gas mass flowmeter is a flow meter based on the principle of thermal diffusion. That is, when the fluid flows through the hair-generating 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 RTDs, one is used as a heat source, and the other is used to measure the temperature of the fluid. When the fluid passes through, the temperature difference between the two has a nonlinear relationship with the flow rate The meter can convert this relationship into a linear output of the measured flow signal.
There are two design methods for the flowmeter manufactured using the thermal diffusion principle: one is based on the constant temperature difference principle; the other is based on the constant power principle and based on a common data model: P / ▷ T = A + B (Q) N. Among them: P --- dissipated power, ▷ T --- temperature difference between the two sensors, Q --- mass flow, N --- exponential coefficient, A, B are coefficients related to the thermal performance of the gas.
Principle of constant temperature difference: ▷ T remains unchanged, and the dissipation power P and the flow rate Q of the fluid increase in an exponential function.
The principle of constant power: the dissipation power is constant, the temperature difference ▷ T and the flow rate Q of the fluid have an exponential decreasing relationship.
