  • Weight vessel of construction database for correcting outputs of load measurement sensing devices
    Patent number: 6412327
    Abstract: A weight vessel adapted for constructing a database for correcting outputs of load measurement sensing devices, in which the weight of the weight vessel can be changed in a desired arbitrary pitch without requiring any superfluous labor, any equipment such as a balance weight, and any dangerous work. The weight vessel includes: a vessel body shaped like a hollow box so that a liquid can be reserved in the inside of the vessel body. An injection inlet is formed in an upper portion of the vessel body and a discharge outlet is formed in a lower portion of the vessel body. A scale is formed on a side portion of the vessel body for indicating a value corresponding to the amount of the liquid reserved in the vessel body. At least the side portion provided with the scale thereon in the sides of the vessel body is formed of a transparent or semitransparent member so that the amount of the liquid in the vessel body can be seen through the transparent or semitransparent member.
