HGTF Target flow meter mainly consists of meter tube , stress element (target plate), sensing elements (force transducer, pressure transducer and temperature transducer), transition part (adjusted according to temperature and pressure), and accumulation calculation, display and output part. Refer to the following figure for the structure\uff1a<\/p>\n
<\/p>\n
The stress element (target plate) is placed at center of measurement tube (instrument body) coaxially, with rigid connection with transducers. When measured medium flows at certain velocity (m\/s), this medium has certain momentum that directly acts on the stress element (target plate). Due to rigid connection between stress element and transducer, the transducer is subject to direct force F generated by fluid momentum. This force is related to flow velocity V, medium density \u03c1 and area of target subject A , the relation meet the formula:\u00a0 F = CD<\/sub> \u03c1 V2<\/sup> A \/ 2<\/p>\n F\u2014force on target plate;\u00a0 \u00a0CD\u2014resistance coefficient;\u00a0 \u00a0P\u2014fluid density, kg\/m3;\u00a0 V\u2014fluid velocity, m\/s;\u00a0 \u00a0 A\u2014area of target plate subject to force, m2 <\/p>\n
