摘要： The invention relates to a measuring device for measurement of the volumetric flow of liquids, in particular for the measurement of dewatering rates from paper machines, having a container for receiving a liquid whose volumetric flow is to be measured, whereby the container has a bottom on which the liquid collects, and having an inlet for the liquid and an outlet for the liquid, whereby inserted in the outlet is a measuring aperture which has an opening for the outflow of liquid from the container. The measuring aperture opening extends upward in a vertical direction in the container, starting at an overflow level at a defined distance above the container bottom. Also, the measuring device has a pressure sensor which is arranged in or on the container, at least partly below the measuring aperture opening, in order to measure the static pressure in a liquid column collecting in the container as the result of the inflowing liquid. The measuring device of the invention including a lower region of the measuring aperture opening that can be closed in order to raise the overflow level by a defined extent for checking the calibration of the measuring device.
