How to choose the right flow meter for different working conditions?

How to choose the correct flow meter under different working conditions. The correct choice of flow meter is of great significance for the measurement of flow. Choosing different flow meters under the same working conditions will definitely have a considerable impact on the final measurement results. A large difference, if improperly selected at the beginning, can even lead to the inability to carry out quantitative measurements and damage to the instrument. Therefore, it is necessary for users to have a correct understanding of how to choose a suitable flow meter, understand some basic selection methods, and Helps create errors when selecting instruments. In order to ensure that the flow meter can be used well and effectively in the production site process, the selection of the flow meter must generally be based on the medium that needs to be measured at the production site. This article lists a variety of media conditions, which users can use as a reference for their own flowmeter selection: For media with high concentration and solid particle content such as mortar and electropowder slurry, the type of flowmeter that should be selected is: electromagnetic flowmeter. For medium with large flow rate of tap water, the types of flowmeters that should be selected are: intelligent electromagnetic flowmeters and ultrasonic flowmeters. Others such as vortex flow meters, orifice flow meters, etc. are also available. For turbid liquid media such as sewage and paper pulp, the types of flowmeters that should be selected are: 1. Ultrasonic flowmeter and intelligent electromagnetic flowmeter. However, when selecting an electromagnetic flowmeter, it should be considered that the liquid does not contain much air or bubbles. For oil media such as petroleum and diesel, the type of flow meter that should be selected is: ultrasonic flow meter. For gas media, the types of flow meters that should be selected are: 1. Ultrasonic gas flow meter. 2. Vortex flowmeter. If the gas temperature exceeds 300°C, a pneumatic flow meter can be selected. For liquid media with many bubbles, the type of flow meter you should choose is: ultrasonic flow meter. Using this type of flow meter to measure fluids with bubbles has a very good effect. For media with low conductivity such as pure water and demineralized water, the type of flow meter you should choose is: Ultrasonic flow meter is very suitable for measuring such fluids. For highly corrosive media such as acids and alkalis, the types of flowmeters that should be selected are: 1. Electromagnetic flowmeters with acid and alkali resistance lining. 2. External clamp-on ultrasonic flowmeter.
