A deformation verification system of a vehicle body includes a dip tank in which fluid is contained. The dip tank has a transparent window from the outside to see the inside. A moving device is configured to lower the vehicle body into the fluid, to move the vehicle body in the fluid and to raise the vehicle body. A camera is installed to detect the form of the vehicle body through the transparent window.

A measurement method and a measuring assembly are provided, and the measuring assembly enables the measurement of the non-destructive and time-dependent change of solid precipitation in drilling fluid (mud) in static conditions. A measurement method and measuring assembly suitable for use in both in the laboratory and in the field, which is low cost and provides ease of application, has been developed. This method and assembly allow reliable temperature-dependent measurements of the change in the densities of drilling fluids of various densities, containing clays, some chemicals polymers and inert solids like barite (BaSO.sub.4).

The method can determine a density of concrete based on the measured buoyancy of a buoy immersed in fresh concrete contained in a ready mix drum and rotatable therein as the drum is rotated, the method can include obtaining a first measurement of a force applied to the buoy while the buoy is being moved tangentially in the fresh concrete, obtaining a second measurement of a force applied to the buoy while the buoy is being moved tangentially in the fresh concrete by rotation of the cylindrical wall, obtaining an indication of the buoyancy of the buoy in the concrete including factoring out the yield effect based on at least the first measurement and the second measurement.
