摘要	There are two ways to design nuclear electronics for a dual energy,gamma ray multiphase flow meter. The advanced way is based on high speed A/D data acquisition and DSP digital signal processing, but it involves a complicated system structure and a huge data flow; the conventional way is based on the technique of photon pulse counter, which is complicated in electrical design, but simple in system structure due to its low data flow, Both systems are studied in the Multiphase Flow Laboratory, Institute of Mechanics, Chinese Academy of Sciences. In this paper, the instrumental designs on the technique of photon pulse counter will be mainly discussed, including the gamma ray sensor's characteristics, signals of sensor, preamplifier, filter and shaping amplifier, DC base shift correcting circuit, narrow windows of energy spectroscopy, programmable pulse count acquisition system
