Microwave apparatus and method for measuring fluid mixtures |
| abstract |
Apparatus for measuring the concentration of one material such as water in another material such as crude or refined oil including a coaxial microwave transmission line (14) formed by a conduit for receiving the material and a center conductor (22) which is sheathed with a dielectric covering (27) which is operable to prevent short circuiting of the transmission path. An oscillator circuit (30) is coupled to the transmission line and is driven by a free-running voltage controlled oscillator and a signal receiver monitors the change in frequency caused by impedance pulling of the oscillator due to the change in the dielectric constant of the mixture. Incident and reflected or transmitted power with respect to the measurement section is measured to determine whether an oil-in-water or water-in-oil emulsion is present to verify the concentration of one fluid in the other for a particular operating frequency. |
