The characteristics of disphragm-type gas meter has been investigated experimentally. For a better control of experimental environment fresh water was used as flowing fluid. Flow rate, inlet pressure and mass of disphragm were varied as controlling parameters and the corresponding pressure drop was measured and summarized as function of several dimensionless parameters chosen. Also over-all function of the gas meter during operation was video taped and analysed for better understanding of mechanical links used. Based on the experimental and numerical results a design procedure of gas meter's possible reading or functional errors are addressed with their practical remedies.
