Abstract
A vortex meter for measuring a flow rate of a fluid has a flowtube and a bluff body positioned in the flowtube for shedding vortices in the fluid when the fluid flows through the flowtube. The vortex meter has a sensor positioned to detect the vortices. The bluff body has a forward-facing surface and an abrasion-resistant cladding covering the forward facing surface. The bluff body suitably also has a projection extending downstream from the forward-facing surface. The bluff body suitably has an abrasion-resistant cladding covering at least a portion of the projection. In one embodiment, the entire bluff body is completely covered by the abrasion-resistant cladding. The inner surface of a segment of the flowtube can also have abrasion-resistant characteristics.
