Current market conditions demand superior and reliable products that are competitively priced. This implies industries improve the overall efficiency of equipment & plant processes and simultaneously conserve energy for achieving desired results. Flow measurement is becoming crucial for conserving energy for various utility measurements such as water, compressed air, natural gas, etc. Flow measurement is also important for various other process gases for emission controls. With strict emission norms, process efficiency needs to be tightly controlled where flow measurement is the ultimate requirement.
Leomi Insertion thermal mass flow meter design is based on Constant Temperature Anemometry combined with digital precision over temperature control. The physical principle of thermal dispersion from a heated element to the ambient medium (example: 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 flowing 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 per figure shown)
