WHAT ARE THE DIFFERENT TYPES OF GAS FLOW METER
DIFFERENT TYPES OF GAS FLOW METERS Thermal mass flow meters — Thermal mass flow meter s, 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. 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. 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...
