Abstract

The invention belongs to the technical field of flow measurement, in particular to a plug-in type semi-parabola multi-point pressure tapping flow sensor. The plug-in type semi-parabola multi-point pressure tapping flow sensor comprises a pressure tapping structure, a T-shaped mounting pipe base and a pressure detection element. A fluid flows through a pressure detection pipe, total pressure is measured at one side of a positive pressure hole of an incident flow surface, static pressure is measured at one side of a negative pressure hole of a back flow surface, the two pressure becomes stable and reliable after being equalized by means of a positive pressure equalizing pipe and a negative pressure equalizing pipe, a pressure difference is generated between the two pressure, and the pressuredifference is transmitted to a differential pressure transmitter and a flow totalizer by means of a positive pressure tapping pipe and a negative pressure tapping pipe, so that flow measurement is realized. The plug-in type semi-parabola multi-point pressure tapping flow sensor adopts semi-parabola pressure tapping, improves the precision and stability of the flow sensor, and greatly increases the measuring range ratio of the flow sensor, so that the differential pressure type flow sensor has better application prospects, and the plug-in type semi-parabola multi-point pressure tapping flow sensor has the advantages of high precision, wide measuring range, high reliability, small pressure loss and the like.

Description

technical field [0001] The invention belongs to the technical field of flow measurement, and in particular relates to a plug-in semi-parabolic multi-point pressure-taking flow sensor. Background technique [0002] The plug-in flow sensor in the prior art, due to the small pressure-taking hole, narrow pressure-equalizing chamber, full-insertion structure, etc., often has the problem of positive pressure hole clogging during use, which greatly reduces the reliability of flow measurement , thereby affecting the flow measurement accuracy. For many important occasions, when flow output participates in on-site interlock control, low flow measurement accuracy will directly bring huge hidden dangers to production. [0003] Therefore, in order to overcome the problem of positive pressure hole blockage caused by the small pressure hole of the plug-in flow sensor in the prior art, the narrow pressure equalization chamber, and the full insertion structure, it is necessary to design a f...
