Difference between turbine flow meter and gear flow meter?
Two commonly used types of flow meters are turbine flow meters and gear flow meters. It is not known how to choose one of these flowmeters when shopping. They differ in working principle, applicable range and accuracy. When choosing a flowmeter model, you should choose the appropriate model according to different fluid properties and the actual use of the environment, which can improve the accuracy and stability of the measurement.
Overview
Differences in working principle：
Turbine flow meters utilize the effect of fluid pressure or flow kinetic energy to generate vortices and measure the rotational frequency and flow rate, thus calculating the flow rate of the fluid.
Gear flowmeter is through the inflow of fluid into the gear chamber, which pushes the gear to rotate, by calculating the rotation frequency of the gear to measure the flow rate of the fluid.
Differences in range of application：
Turbine flow meters are suitable for measuring low to medium flow ranges of liquids or gases, and are usually suitable for cleaner fluids or for operation in transparent pipelines. Turbine flowmeters are usually compact and simple, can fit into smaller pipelines, and are easy to maintain and install.
Gear flow meters are suitable for higher flow ranges of liquids and gases, especially if the fluid is viscous or contains particles. Gear flowmeters are usually bulky and complex, are suitable for larger pipelines, and require regular maintenance and cleaning.Differences in accuracy
Turbine flowmeters can achieve extremely high accuracy, typically 1% or better.
Gear flow meters, on the other hand, are slightly less accurate, with accuracies typically ranging from 0.5% to 1%.
