Metal tube float flowmeter manufacturers recommend that selection to focus on these three points

Project Overview

　　Metal tube float flowmeter is a commonly used flow measurement instrument, widely used in liquid and gas flow measurement. When choosing a metal tube float flowmeter, manufacturers usually recommend focusing on three key factors: medium, temperature, and pressure, which are analysed in detail below:

　　1. Medium:

　　Chemical properties of the medium: different media have different chemical properties, such as corrosive, flammable, explosive and so on. In the selection of flowmeter, you need to ensure that the flowmeter material can withstand the chemical corrosion of the medium, to avoid the flowmeter due to media corrosion and damage or inaccurate measurement.

　　Density and viscosity of the medium: the density and viscosity of the medium will affect the measurement accuracy and stability of the flowmeter. Therefore, in the selection of flowmeter, need to consider the density and viscosity range of the medium to ensure that the flowmeter can be measured accurately.

　　The purity of the medium and the content of particles: If the medium contains impurities or particles, it may cause interference or damage to the measurement of the flowmeter. Therefore, when choosing a flowmeter, you need to consider the purity of the medium and particle content, choose the appropriate type of flowmeter or take filtering measures.

　　2. Temperature:

　　Operating temperature range: metal tube float flowmeter operating temperature range is limited. When choosing a flowmeter, you need to ensure that the operating temperature range of the flowmeter can cover the temperature range of the actual working environment, to avoid damage to the flowmeter due to the temperature is too high or too low, or inaccurate measurement.

　　Temperature effects on the medium: changes in temperature may affect the density of the medium, viscosity and other physical properties, thereby affecting the measurement accuracy of the flowmeter. Therefore, in the selection of flowmeter, need to consider the effect of temperature on the medium, and the corresponding temperature compensation or choose the flowmeter with temperature compensation function.

　　3. Pressure:

　　Working pressure range: metal tube float flowmeter working pressure range is also limited. In the choice of flowmeter, you need to ensure that the working pressure range of the flowmeter to meet the pressure requirements of the actual working environment, to avoid damage to the flowmeter due to high pressure or inaccurate measurement.

　　Pressure on the impact of the flowmeter: pressure changes may affect the measurement accuracy and stability of the flowmeter. Therefore, in the choice of flowmeter, you need to consider the impact of pressure on the flowmeter, and choose the flowmeter with pressure compensation function or take corresponding pressure stabilisation measures.

　　In summary, the choice of metal tube float flowmeter, you need to comprehensively consider the medium, temperature, pressure, the three key factors. By understanding the chemical properties of the medium, density, viscosity and other characteristics, to determine the operating temperature range and operating pressure range, as well as consider the temperature and pressure on the flowmeter, you can choose a metal tube float flowmeter suitable for the actual working environment and measurement needs. At the same time, it is also necessary to pay attention to the choice of flowmeter produced by regular manufacturers to ensure product quality and after-sales service.
