Abstract :
In this paper we present a highly integrated, Field Programmable Gate Array (FPGA) based induction measurement system for low conductivity object applications. Exploiting under-sampling and demodulation techniques, the system can operate at higher frequencies (>;10MHz) than previously reported. Details are discussed in both hardware and software aspects. Simulations and experimental results for two gas/liquid flow cases are given to verify the performance of the system.
