MEASUREMENT PRINCIPLE
LEOMI calorimetric Insertion Thermal Mass Flow Meter work on the physical principle of thermal dispersion from a heated element to the ambient medium (eg. air or gases). This is affected by the velocity, density (temperature and pressure), and by the characteristic of the medium. The amount of needed energy is a function of the temperature difference ∆T and the mass flow.
Gas flows through two RTD Pt-100 one reference (Tref) and the other Heater (Th). The temperature difference (over-temperature) ∆t between the reference sensor (medium temperature) and the heater sensor is controlled constantly. As per King’s Law, the higher the mass flow rate, the higher the cooling effect of the heater sensor, thus higher the power required to maintain the differential temperature constant. Therefore the heater power is proportional to the gas mass flow rate.
As we can see besides, there is a correlation between velocity (m/s) and power (mW) of the flow. If the velocity increases, power increases and vice-versa. And when the velocity starts to decrease, the power will simultaneously decrease. We have shown here velocity 0-70 m/s and power 100-1000mW. The bubbles in the pipe indicate air or gas flow. In which, the red bubbles show the heating effect on flow by the heater sensor.
