Different Types of Gas Flow Meters in India
1. Thermal mass flow meter
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 flow meter
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.
