摘要
Disclosed is a method and an apparatus for measuring the pressure of fresh concrete and similar liquid materials during placement, in which a movable component is displaced under the pressure of concrete or other liquids and is used as an indicator of the pressure exerted by the concrete or liquid material on the device. Mechanical resistance of the movable component is achieved using a calibrated spring or similar mechanical resistance element. The movable part consists of a pressure plate attached to a scaled cylindrical core, calibrated to provide measurements of the external concrete or liquid pressure. The movable component and mechanical resistance element are installed in a casing with flanges to attach the apparatus to the formwork or vessel.
