Role of Turbine Flowmeter in Measuring the Flow of Low Viscosity Fluids and Liquids
Classic turbine flowmeters use propeller type turbines in a closed circular conduit. The turbine is mounted on low friction bearings and its rotation is detected through the chamber wall by one of a variety of detector types. These turbine flowmeters have good linearity in larger diameters but as the pipe bore reduces the efficiency of the flowmeter also reduces. How Turbine Flowmeters Help Measuring the Flow of Low Viscosity Fluids? For measuring the flow of low viscosity fluids within smaller diameter pipe applications – TrigasDM supplied turbine flowmeters employ a design where the flow of fluid is directed at the turbine that is mounted on robust low friction sapphire bearings. The geometry of the turbine and the fluid chamber ensures that the rotational speed of the rotor is proportional to the flow rate through the device. The use of this radial arrangement advantageously allows more energy to be imparted into the turbine so the bearing drag is far less important. Furt
