Abstract

The invention discloses a flow measurement system capable of adjusting a measuring position. The flow measuring system capable of adjusting the measuring position comprises a measurement device with a telescoping mechanism, a high static tube cavity, a low static tube cavity, a differential pressure transmitter and an analysis display device, wherein the measurement device with the telescoping mechanism includes main measurement elements, a fixing flange and a servo mechanism; the main measurement elements are connected with the servo mechanism; the servo mechanism is installed on the fixing flange. The main measurement elements are connected with the high static tube cavity and a low static tube cavity which are fixed on the fixing flange through a pressure tapping hose, the high static tube cavity is connected with a high static input end of the differential pressure transmitter, the low static tube cavity is connected with a low static input end of the differential pressure transmitter, the differential pressure transmitter is connected with a differential pressure signal which is output to an analysis display device, and the analysis display device gives the measuring value of air speed. The flow measurement system has the advantages that the measurement positions of the main measurement elements can be adjusted, more measurement elements can be arranged, so that the multi-point measurement can be realized.

Description

technical field [0001] The invention relates to the field of measurement technology, in particular to a flow measurement system with adjustable measurement positions. Background technique [0002] In engineering practice, flow measurement devices or flow measurement sensors are generally designed point-to-point, that is, designed according to corresponding given working parameters and working conditions. [0003] In practical applications, some projects have adjusted the operating parameters and conditions of the actual working conditions to meet the needs of capacity expansion or upgrading. The operating parameters and conditions of the actual working conditions generally have a large gap with the original design working conditions and design parameters, resulting in a large measurement error of the flow sensor designed according to the given parameters of the design, which cannot be used or even scrapped. [0004] Large rectangular closed pipes, based on strength consider...
