weirplate

Etymology

From weir + plate.

noun

  1. A metal plate that forms an obstruction to adjust the flow of a weir.“Why a difference in temperature between the water and the weirplate should cause the water to spring clear at low heads cannot very well be explained.”
  2. An adjustable plate that controls the amount of liquid held in a chamber of a machine.“The weirplate at the bottom, inside the drum at F, serves the same purpose as in the machine you have seen — namely, to provide an inner wall of water of the desired thickness within the drum.”
