The above mentioned are actually related to the physical properties of the fluid.
The influence of the physical properties of the fluid on the flow characteristics is one of the major problems in the design and use of the flowmeter. The influence of physical properties on the flowmeter varies depending on the working principle. At present, the general flowmeter has some physical properties such as: 1 density; 2 viscosity; 3 conductivity; 4 speed of sound; 5 thermal conductivity; 6 isentropic index; 7 specific heat capacity; 8 chemical corrosion; 9 scale; 10 lubricity; 11 phase change;
Why do we have to grasp the physical parameters? What are the uses of physical parameters?
1. Selection basis The selection of the flow meter is mainly to understand the performance of the instrument and the physical properties of the measured medium. The physical parameters of the fluid are an important part of the characteristics of the measured object. When used in the field, there are many instances where measurements are not met due to insufficient or inaccurate control of fluid properties.
2. Flowmeter Design Calculation In the design calculation of the flowmeter, the physical property parameter is one of the main parameters. To make the design calculation accurate and reliable, the provision of basic data is indispensable.
3. Field use and maintenance fluid physical property change is one of the main causes of flow measurement additional error when used in the field. To reduce the additional error of the measurement, the influence of the physical property parameters on the characteristics of the flowmeter should be thoroughly discussed.
At present, there are some problems in the physical property parameters of the instrument industry. 1. The lack of online physical property measuring instruments, poor quality, and narrow application scope. In order to improve the accuracy of flow measurement, it is urgent to develop online physical property measuring instruments to make online corrections in the measurement process. Density and viscosity on-line measurement instruments (transmitters) are not only technically complex, expensive, and have a narrow range of applications, so they cannot be widely applied.
2. The accuracy of the physical parameter data is low, the confidence is poor, and the data is not uniform. The fluid property parameters used for flow measurement are generally taken from various physical, chemical, and engineering manuals. Due to mixed sources and inconsistent data, various manuals require different objects. It is difficult to meet the requirements of high accuracy in flow measurement and the need for clear numerical accuracy. Many fluids have insufficient or even no physical data, especially high-parameter (high pressure, high temperature, low temperature, high vacuum, etc.) fluids and multiple fluids (fluids). The physical parameters of the mixture) are not only poor in confidence, but even completely absent;
3. The lack of a dedicated physical property manual Considering the influence of fluid property parameters on the measurement accuracy, foreign countries have established national standards for the physical properties of minority parameters, but it is more realistic to manually compile a special manual for physical properties of flow measurement for a large number of physical parameters. Can provide more complete and unified data. In particular, with the popularization of computer use, physical parameters can no longer satisfy the requirements only with charts, and it is urgent to provide various types of calculations for ease of use.
