Turbine Flow Meter Working Principle

I had a chance to work with turbine flow meters in a variety of applications in são paulo.

Turbine flow meter working principle. As fluid flows through the turbine meter it impinges upon turbine blades that are free to rotate about an axis along the center line of the turbine housing. Historically turbine flow meters figure 1 were preferred for clean filtered low viscosity fluids. A turbine flow meter has a fairly simple design simple working principle and straightforward installation and maintenance. Blades on the rotor are angled to transform energy from the flow stream into rotational energy.

Turbine flow meter principle. The working principles and design of turbine flow meters are well documented. A turbine flow meter should not be operated at high velocity because premature bearing wear and or damage can occur. The rotor shaft spins on bearings.

With comparatively low pressure drop for in line meters turbine flow meters deliver unprecedented accuracy. When the fluid moves faster the rotor spins proportionally faster. Wide range of measuring with very lower flow. Turbine flowmeters use the mechanical energy of the fluid to rotate a pinwheel rotor in the flow stream.

The angular velocity of the rotor results in the generation of an electrical signal ac sine wave type in the pickup. Turbine flow meter is a volumetric measuring turbine type. Care should be taken when operating these flowmeters above approximately 5 percent of maximum flow. It consists of a multibladed rotor called turbine wheel which is mounted 90 to the axis of the flowing liquid as shown in fig.

How turbine flowmeters work. A turbine flow meter is less accurate at low flow rates due to rotor bearing drag that slows the rotor. The flowing fluid engages the rotor causing it to rotate at an angular velocity proportional to the fluid flow rate. Please subscribe to this channel.

A turbine flow meter is used for volumetric total flow and or flow rate measurement and has a relatively simple working principle. Q t turbine flow meter.
