Description

technical field [0001] The invention belongs to the field of petroleum equipment, and in particular relates to an automatic cleaning device and method for a density meter of a cement truck. Background technique [0002] Due to its structural characteristics and application characteristics, petroleum machinery and equipment are suitable for intelligent development, which is also an inevitable requirement for the development of oilfield production. Density meter, as the core component of oilfield equipment, plays an irreplaceable role in controlling the density and flow of materials entering the well. How to ensure that the density meter always accurately measures the density is the direction of efforts to improve the quality of oil and gas field operations. With the prolongation of equipment usage time, performance degradation of each component is inevitable. As an electronic component with strict requirements on the measurement environment and high measurement accuracy, en...
