Abstract
In order to measure the relative proportions of oil, water and gas passing along a pipe, the pipe is passed through the coils of a number of coil resonators having different resonant frequencies. By measuring changes in the resonant frequencies of the coil resonators the proportions of oil, water and gas in the flow through the pipe can be calculated.
