A gas meter measures energy indirectly by recording the volume of gas used. Horizontal-Axis Wind Turbine Working Principle. The savonius wind turbine working principle can be easily explained because this is considered as the most streamlined turbine when compared with other turbines. Due to their use of a heated wire, they are generally NOT suitable for use in hazardous areas where intrinsically safe equipment is required. As per the datasheet, a wind speed of 2.4km/h (1.4912 mph) causes the switch to close once per second. The main working principle of coriolis flow meters is the use of a vibrating tube where the flow of gas can cause changes in frequency, or phase shift proportional to the mass flow rate. The display mode is also divided into two options: pointer display and digital display. As per the datasheet, a wind speed of 2.4km/h (1.4912 mph) causes the switch to close once per second. This figure can then be converted to a measure of energy by multiplying it by the calorific value of the gas..
