Insertion Thermal Mass Flow Meter in India.

Over two decades of unremitting efforts in the fields of technologies and automation have inspired the LEOMI founders to start a manufacturing venture in search of industrial measurement solutions (Insertion Thermal Mass Flow Meter) that optimize lives. LEOMI provides affordable and reliable solutions with the expertise of MTS Engineers Pvt Ltd, which has promoted reputed companies for industry-specific technologies. LEOMI strives to hunt down the harsh conditions of industries by customizing industrial processes with German standards of Soft flow in Gandhi agar, Gujarat. LEOMI is a 9001:2015 company that ensures that products and services meet customer needs through an effective quality management system.

 

Insertion Thermal Mass Flow Meter

LEOMI thermal mass (calorimetric) flow meters work on the physical principle of thermal dispersion from a heated element to an ambient medium (such as air or gases). It is affected by velocity, density (temperature and pressure), and the characteristic of the medium. The amount of energy required is a function of the temperature difference T and the mass flux.

 

The 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 continuously. According to King's Law, the higher the mass flow rate, the greater the cooling effect of the heater sensor, thus requiring more power to keep the differential temperature constant. Hence the power of the heater is proportional to the gas mass flow rate.

 

As we can see next, there is a relationship between velocity(m/s) and power (mW) of flow. If velocity increases, power increases, and viceversa. And when the velocity starts decreasing, the power will decreasesimultaneously. We have shown here velocity 0-70 m/s and power 100-1000mW.Bubbles in the pipe indicate the flow of air or gas.

ADVANCEMENT IN AIR & PROCESS GAS FLOW MONITORING IN CEMENT PLANTS FOR PROCESS OPTIMIZATION

Image
Cement Industry is one of the crucial core sectors for the development of construction and infrastructure with currently approx. 4.4 billion Tonnes of cement was produced in the world in the year 2021. The largest cement producer is China with more than 55% capacity and thereafter India accounts for the second largest product with around 7% of capacity. After the COVID-19 pandemic, there was a sudden rise in demand from rural and urban infrastructural developments across the world and mostly in undeveloped countries. Initiatives such as the Smart City project by India will see a long-term demand for cement products which will see huge technological upgradation of existing cement plants for cost and energy optimization. The cement industry is one of the most intensive energy consumers in the industrial sectors. Energy consumption represents 40% to 60% of production costs. Additionally, the cement industry contributes around 5% to 8% of all man-made CO2 emissions. Due to increasing deman

  One of the essential foundational industries for the growth of infrastructure and building is the cement industry; in 2021, the globe produced about 4.4 billion tons of cement. China is the world’s largest cement producer, with over 55% of the global capacity; India comes in second, with over 7% of the global capacity. Following the COVID-19 epidemic, there was an abrupt increase in demand for both urban and rural infrastructure expansions worldwide, primarily in developing nations. Long-term demand for cement products will result from initiatives like India’s Smart City project, which will push current cement plants to greatly upgrade their technological capabilities in order to optimize energy and cost. Among all industrial sectors, the cement industry is one of the ones that uses the most energy. Between 40% and 60% of industrial expenses are attributed to energy use. In addition, the cement sector accounts for 5% to 8% of global emissions of CO2 produced by humans. Today’s cement
