The Wedgemeter has a solid V-shaped flow restriction which makes it extremely robust. It is bi-directional and is particularly suitable for fluids with a high solid content, erosive/abrasive fluids and those with a high viscosity.
The smooth flow path has good self-cleaning characteristics and performance is not dependent on maintaining sharp edge profiles. The element design allows solids to pass through the restriction without accumulating. The meter characteristic remains constant down to low Reynolds Numbers, making it suitable for high-viscosity liquids.
When used with high-viscosity liquids or with liquids which could block conventional small-bore impulse pipework, versions with large bore tappings or tappings to take chemical tee DP transmitter elements are available.
There are three designs:
- WMP NPT tapped transmitter connections for low viscosity and relatively clean fluids.
- WMC Chemical Tee transmitter connections for high viscosity and fluids with high solids content.
- WMF Flanged transmitter connections for high viscosity and fluids with high solids content.
