Jämförelse av två mätmetoder för mindre gasvolym

Abstract [sv]

Two different methods for measuring biogas production were used, gas meter and gasbags. The gas meters were electronic and counted each time a certain gasvolume passed through them. The gasbags collected the gas that hade passed through the gas meter until a manual measuring could be done. The two different methods gave the same result for a volume at three liters but for a volume around 0,2 liters they did not. Accuracy and precision for the gasbags was more exact than for the gas meters even if the method was difficult with a lot of different elements that could affect the result. The gasbag method was more complicated and took longer time than the gas meter, which was an easy working technic that wasn´t time consuming. But both of the methods gave a fall off . For the gasbags the values falled off because of leakage and for the gas meter it falled off because of dubble counting and that the meters stopped count for a while. The advantage of the gasbags is that you can measure the gas total compound. The benefit of the gas meter is that you can measure changes in the gas flow over time.
