Abstract :
Measurements of water flow at different velocities in two kinds of pipe are made using a sealed positron tracer and annihilation coincidence detection. The main aim is to find the most suitable hardware and software construction for analyzing the liquid flow and velocity profile in a pipe using the ACD method. The present measurements with previous calculations show that the mass flow of water can be measured with an accuracy greater than 1 %.
