This article describes a test instrument that is used to test the flow rate and well diameter of liquids in deep wells. This instrument can measure long distance and temperature up to 180 ℃. This article describes its working principle, characteristics and effects. The method of determining the content of oil and water is given. The methods of solving technical problems such as high temperature resistance and small volume are pointed out. For the first time, a new technology for forming semiconductor circuits with high temperature resistance of up to 200 ° C using ordinary discrete components can be used to develop various high temperature circuits.
