Measurement of discharge and volume component of multiphase fluids is very important in different industries. Multiphase fluid flow measurement is currently being performed with equipment and methods, most of which are commonly used in specific conditions and in fluids with specific characteristics, and are also associated with errors in the conditions used. Measurement of current and volume fraction by electromagnetic method and mutual induction as it does not require separation of phases and non-direct contact with the fluid sensor can be a great method for measuring flow characteristics for different materials with different conditions and requirements. Applying the proposed method in addition to the aforementioned advantages in ease of speed measurement and reproducibility, it is possible to develop and detect flow patterns for different fluids. In this study, a current loop was designed to generate different multiphase flows and the proposed sensor response was recorded under different conditions by the current loop. The method of construction and the results and suggestions for the development of this type of sensor are presented in this thesis. According to experiments generally, the magnetic permeability of the mixture increases with increasing percentage of water in the colloidal mixture and the induced voltage in the secondary coil increases. In this study, different mixtures of phases were placed for testing between two coils and the induced induction voltage was recorded. To test the induction rate, two devices were designed for testing, one being a current loop and the other a jar test device. In the current loop, the ratio of the different phases with different regimes can be established and the signal is examined dynamically; the inductive voltage is measured statically in the secondary winding device. In general, the proposed method can be used to measure the volume of water in the mixture between two coil spaces. The voltage induced in the secondary coil is recorded statically by the voltmeter or board and in the dynamic mode by the board and sampled at specified intervals. In the measurements taken, the voltage induced in the secondary coil for the oil phase did not differ from the air, but for the water, the induction voltage was higher than for the air. Induction voltage for distilled water, municipal water and saturated brine were not significantly different in induction voltage.
