The study of cheaper alternatives to commercially available flow meters in the market continues because cost has since been one of the major factors considered in instrument selection. This study presents the results of an experimental investigation involving the use of Unplastized Polyvinyl Chloride (UPVC) pipe male adapter as an alternative variable head flow meter. Seven test specimens of different geometries were made from NELTEX® 20 mm UPVC pipe male adapter having a throat to diameter ratio, β, of 0.665. The results showed that the values of coefficient of discharge corresponding to geometric variation of the adapter can be determined accurately using an open tank draining model as proven by Torricelli’s Law. Of the seven specimens tried, the shorter and tapered specimen is the better meter geometry based on its higher values of coefficients of discharge which in effect lead to faster discharge times.
