Liquid float flowmeter: how to correctly select and use?

Project Overview

　　Liquid float flowmeter is a commonly used flow measurement instrument, it is through the fluid guided to the float flowmeter, the use of the float in the fluid up and down floating principle to measure the fluid flow. However, under different working conditions and use conditions, the selection and use of float flowmeter need special attention to ensure its measurement accuracy and long-term stability.

　　First of all, the correct selection is the key to the use of liquid float flowmeter. When selecting the type, you need to consider the type of measurement medium, working pressure, flow range, temperature range, viscosity, density and other factors. If the selection is not appropriate, it may lead to a large measurement error or inaccurate measurement. Therefore, before the selection, you need to fully understand and analyse the measurement conditions in order to select the most suitable float flowmeter.

　　Secondly, the correct installation and use is also the key to the normal operation of the liquid float flowmeter. In the installation, according to the characteristics of the measurement medium and the type of flowmeter, reasonable arrangement of the inlet and outlet pipelines, to avoid improper installation of pipelines caused by inaccurate readings of the flowmeter. In use, we must pay attention to keep the flowmeter and the pipeline medium clean, so as to avoid impurities and dirt affect the measurement results. In addition, the liquid float flowmeter used for a period of time, but also need to be regularly maintained and cleaned to ensure its measurement accuracy and long-term stability.

　　Finally, it should be noted that the liquid float flowmeter also has some limitations. For example, for high viscosity media or the need to measure small flows, it may be necessary to choose other types of flow meters for measurement. Therefore, when using the liquid float flowmeter, you need to judge and choose according to the actual situation to ensure the accuracy and reliability of the measurement results.

　　In short, the liquid float flowmeter is a commonly used flow measurement instrument, but the correct selection and use is the key to ensure its accurate measurement. In the selection before the need to understand the characteristics of the measurement medium and the measurement conditions, while in the installation and use of the process need to pay attention to keep the pipeline clean and flowmeter maintenance to ensure its long-term stable work. At the same time, also need to recognise the existence of certain limitations of the liquid float flowmeter, in the actual application of the need to combine with the actual situation for selection.
