Turbine flow meters are the preferred method for clean, filtered and low viscosity fluids. These meters also are known for their accuracy. The inner workings and design of these meters are very well known within the industry. However, like anything, there are pros and cons of using turbine flow meters.
Let’s start with the pros. Turbine flow meters are low cost and easy to install and operate. They rarely have performance issues, as their technology is rather simple. These meters are great for gases and liquids and have a relatively wide envelope of flow to them.
Now the drawbacks. They require frequent calibration. Their installation has to be exact and precise to avoid any errors. They require the fluids passing through to be clean. There are also issues with cavitations and errors due to viscosity changes.
