Momentum type flow sensor probe structure and detection method thereof

Abstract

The invention belongs to the field of flow detection and provides a momentum type flow sensor probe structure and a detection method thereof. The momentum type flow sensor probe structure comprises a differential pressure sensor probe, a detection box and an air source. The differential pressure sensor probe is provided with two pressure detection cavities, each pressure detection cavity is internally provided with a pressure detection end, and the pressure detection ends are used for detecting pressures of fluid in the two pressure detection cavities or differential pressure in the two pressure detection cavities. The detection box is provided with a fluid inlet and a fluid outlet to allow the fluid to internally flow through the detection box, and the detection box is communicated with each of the two pressure detection cavities through a fluid passage. An air supply direction of the air source points to the middle position of the two fluid passages, and the fluid passages and the air source are arranged on two opposite sides of a fluid flow path in the detection box respectively. By the momentum type flow sensor probe structure and the detection method thereof, the problem of competence failure of existing flow sensors in various places due to limitations including low measurement precision, high energy consumption and the like resulted from adoption of traditional power measurement ways is solved.

Description

Technical field [0001] The invention relates to a flow sensor probe, belonging to the technical field of flow sensor monitoring. Background technique [0002] In modern industrial production, especially in the automated production process, various sensors are often used to monitor and control various parameters in the production process, so that the equipment works in normal or optimal conditions, and the products reach the best quality.
