In the field of flow measurement, soap film flow meters and orifice flow meters are two common measurement tools. Although they are all used for measuring flow, there are significant differences in their principles, applications, and usage methods.
Soap film flowmeter: Based on the principle of soap film, when gas or liquid passes through a pipeline, a certain pressure is formed, causing the soap film to flow inside the pipeline. By measuring the velocity of soap film flow, the fluid flow rate can be calculated.
Orifice flowmeter: calculates flow rate by measuring the pressure difference of fluid passing through the orifice. When the fluid passes through the orifice, a certain pressure difference will be generated at the orifice due to changes in flow velocity. By measuring this pressure difference, the fluid flow rate can be calculated.
Soap film flowmeter: mainly used to measure the flow rate of gases and liquids, especially has advantages in measuring high viscosity, high corrosiveness, or high purity fluids. Due to its non-contact measurement method, it has a relatively small impact on the physical properties of the fluid.
Orifice flowmeter: mainly used to measure the flow rate of gases and liquids, especially has advantages in measuring low viscosity, low corrosiveness, or low purity fluids. Due to its simple structure, low cost, and convenient maintenance, it is widely used in industrial applications.
Soap film flowmeter: Usually, specialized measuring equipment is installed on the pipeline to calculate the flow rate by measuring the speed of soap film flow. Due to its non-contact measurement method, it has a relatively small impact on the physical properties of the fluid.
Orifice flowmeter: specialized measuring equipment needs to be installed on the pipeline to calculate the flow rate by measuring the pressure difference of the fluid passing through the orifice. Due to its simple structure, low cost, and convenient maintenance, it is widely used in industrial applications.
In summary, there are significant differences in principle, application, and usage between soap film flow meters and orifice flow meters. In practical applications, suitable flow meters should be selected based on factors such as the physical properties of the fluid, measurement accuracy requirements, and usage environment.
