ABSTRACT:
The petroleum stream watercut monitor includes a test cell having a petroleum stream flowing through it. A microwave transmitter provides microwave energy through an antenna through an isolator. The antenna irradiates the test cell with the microwave energy so that the microwave energy enters the test cell and is reflected from the petroleum stream back to the antenna. A circulator connected to the isolator connects the transmitter to the isolator means and provides microwave energy to the antenna through the isolator and receives from the antenna again through the isolator the reflected microwave energy. An indicator provides an indication of the watercut of the petroleum stream in accordance with the phase difference between the transmitted microwave energy and the test microwave energy.
