HGTF Target Flow Meter
Application: volumetric or mass flow measurement of liquid, Gas or Steam.
Target flow meter has wide applicability, especially in the harsh process of high viscosity, high temperature or ultralow temperature, high pressure where other flow meters are not competent.
Structure of Flange type:
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：
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 ρ and area of target subject A , the relation meet the formula: F = CD ρ V2 A / 2
F—force on target plate; CD—resistance coefficient; P—fluid density, kg/m3; V—fluid velocity, m/s; A—area of target plate subject to force, m2
the flow is calculated as follow fomular:
