turbine type flow rate transducer, sensitive element, hydrodynamic balancingAbstract
The problem of creating devices with turbine primary flow rate transducers, where the sensitive element is balanced by the flow of the liquid, which prevents the rapid deterioration of the sensor support and the loss of the metrological characteristics, is considered. The authors proposed the construction of a primary turbine flow rate transducer with a hydrodynamic sensitive element balancing; a characteristic feature is the presence of the sensitive element axial movement to determine that the analytical dependence, thereby creating a coherent mathematical model generalizes the considered converter. The method of determining the force balancing sensitive element in a wide range of flow rates is described. The influences of the dimensions, number and location of installation of fairings towards the flow axis, the distance between them, as well as liquid hydrodynamic and physical characteristics, on the transducer parameters were studied.References
