Selecting The Right Industrial Paddle Wheel Flow Meter

When selecting a paddle wheel flow metre, the design of the paddle assembly is crucial since it impacts the accuracy and performance of the flow metre. The paddle assembly is the component of the flow metre that includes the paddle wheel and measures the fluid’s flow rate.

A well-built paddle assembly will feature a paddle wheel that is sized and shaped appropriately for the fluid being measured. The size and shape of the paddle wheel will impact the amount of torque required to revolve the wheel and the amount of fluid it can displace. If the paddle wheel is too small, it may not be able to precisely measure the fluid’s flow rate, and if it is too large, it may cause excessive turbulence in the stream, which can also damage the measurement’s precision.

The design of the paddle assembly influences the location of the paddle wheel in the fluid. If the paddle wheel is too close to the pipe walls, it may be influenced by the turbulence caused by the walls. This can result in inconsistent paddle wheel rotation and erroneous measurements. A properly built paddle assembly will position the paddle wheel in the middle of the fluid flow, where there is the least amount of turbulence.

Fluid turbulence can impact the measuring accuracy of a paddle wheel flow metre. The paddle wheel may revolve irregularly and provide erroneous measurements if turbulence is present. Turbulence can be caused by variables such as the fluid’s velocity, viscosity, and temperature. By putting the paddle wheel in the middle of the fluid flow, a well-designed paddle assembly reduces the impact of turbulence on the paddle wheel.

The design of the paddle assembly is crucial when selecting a paddle wheel flow metre since it impacts the flow meter’s accuracy and performance. Important considerations include the paddle wheel’s size, shape, and position in the fluid since they can affect the amount of torque required to rotate the wheel and the amount of fluid it can displace. A well-designed paddle assembly will reduce the impact of turbulence on the paddle wheel by putting it in the centre of the fluid flow and delivering precise data.
