WHAT ARE THE DIFFERENT TYPES OF GAS FLOW METER

 


DIFFERENT TYPES OF GAS FLOW METERS

  1. Thermal mass flow meters —Thermal mass flow meters, thermal dispersion or immersible mass flow meters, or gas flow meters, are a type of instrument for measuring the rate at which fluid (usually air) passes through a pipe. The thermal part refers to the fact that the device is heated and differential (not absolute) in pressure across it will cause flow because of this temperature gradient, i.e., if the side without a pressure difference is hotter than the other side, then the flow will occur from hot to cold.

  2. Differential Pressure Based Flow Meter — Differential Pressure flow meters measure velocities in fluids by reading the pressure loss across a pipe constriction. These meters can employ laminar plates, nozzles, or Venturi tubes to create an artificial constriction.

  3. Coriolis flowmeter — Coriolis mass flow meters are very useful to have around. It’s helpful when you have a large amount of liquid or even gas that needs to be measured. Coriolis mass flow meters help you get a good idea about how much fluid is passing through, and in which direction too. These meters are typically made out of metal, though there are versions available that can be used with liquids and gases that don’t react well to metal.

  4. Turbine flow meter — A turbine Flow Meter is an instrument used to measure liquid flow in pipelines and tanks. It is also known as a rotating impeller flowmeter. The turbine meter uses the principle of measuring the rotary motion of a turbine, into an electrical signal.

  5. Ultrasonic Flow Meter – Clamp-on Type — Ultrasonic clamp-on flow meters measure flow to determine the transit time of a liquid or gas. Using sound waves for measurement, ultrasounds can accurately monitor changes in flow. Ultrasonic clamp-on flow meters are used for primary applications involving liquids, gasses, and other substances

  6. Vortex Flow Meter — Vortex flowmeters operate using vortex shedding to determine the amount of water flow. The technology is based on the principle that vortexes are shed when an oscillating fluid flows past a bluff body, such as a sphere or disk which has been inserted into the fluid flow.

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
