“…The obtained estimate of the uncertainty of the developed transducer confirms that it is possible to provide higher accuracy characteristics compared to known capillary devices of continuous measurement of liquids' viscosity and density [3][4][5]10]. The authors' principles of designing transducers with maximum measuring sensitivity provide the least value of uncertainty in a given measurement range and reduce the nonlinearity of the transform function.…”

“…Promising for solving the problems of measuring the properties of fluids is the hydro-gas-dynamic throttle method, based on which many measuring transducers are built [2][3][4][5][6][7][8][9][10][11]. The main components of hydro-gas-dynamic measuring transducers are throttle elements.…”

The paper proposes a measuring transducer of the physical-mechanical parameters of a Newtonian fluid based on a throttle bridge measuring diagram with identical turbulent and laminar throttles in opposite arms. A mathematical model is built for the throttle bridge transducer of the combined parameter, which depends on the kinematic viscosity and density of the fluid. The problem of parametric optimization of the proposed measuring transducer is formulated and analytically solved in the paper. The authors calculated the transform function of the measuring transducer of the combined parameter of jet fuel.

“…Kinematic viscosity and density transducers are known with a combination of laminar and turbulent throttles connected in a bridge measuring diagram. The operation principle of transducers is based on balancing the bridge diagrams by changing the total flow rate of the controlled fluid [10]. In [11], the transducer of the combined parameter depending on dynamic viscosity and density is also developed based on the bridge diagram with oppositely connected laminar and turbulent throttles.…”

The paper presents the analysis of the resources of structural and parametric optimization of gas-hydrodynamic measuring transducers of physical and mechanical parameters of fluids. Resources such as the number of throttles and their arrangement in the diagram, type of throttle elements, measuring channels with a certain type of output signal, the supply mode of the measuring transducer can be integrated into the design process of the measuring transducer of a specific parameter. A mathematical apparatus based on set theory and combinatorial analysis is proposed for synthesizing the possible structures of throttle diagrams, graph theory – for forming a set of measuring channels. The authors have given examples demonstrating the possibilities of building different diagrams of measuring transducers using the resources for structural synthesis. The proposed resources are the means of structural and parametric optimization for synthesizing the gas-hydrodynamic measuring transducers with optimal characteristics.
