Abstract:
A milk meter for measuring the volume of milk provided by a milking machine for milking animals, wherein the milk meter comprises at least one tubular measuring section through which, in operation, milk to be measured flows, and wherein the tubular measuring section is provided, in the flow direction of the milk, with at least two spaced apart measuring electrode assemblies for use of an EGT (Electrical Capacitance Tomography)-technique, and with signal processing means which are designed for determining data with respect to the volume of the milk flowing through the at least one measuring section from measuring signals provided by the measuring electrode assemblies.

Abstract:
A method for measuring a milk flow with the aid of at least one light sensor, wherein the method comprises the following. steps : a. directing the milk flow through a channel (6) with predetermined dimensions, such that a filling height of the channel with milk of the milk flow depends on the magnitude of the flow rate of the milk flow; b. measuring with the aid of at least one light sensor (32) for multiple different areas lying within the channel, per area, whether milk or no milk of the milk flow is present in the respective area, whereby these areas are illuminated; c processing in combination the information on the milk of the milk flow being present or not per area for determining the amount of milk, the magnitude of the velocity of the milk flow in the channel and/or the flow rate of the milk flow.
Abstract:
A sample taking apparatus for obtaining a sample liquid stream from a main liquid stream wherein the sample liquid stream is a predetermined percentage of the main liquid stream, wherein the sample taking apparatus is provided with at least one liquid stream divider for dividing a basic liquid stream into a first liquid stream and at least a second liquid stream, wherein the liquid stream divider is provided with a basic gutter provided with a basic inlet and a basic outlet, a first successive gutter and at least a second successive gutter wherein the first successive gutter is provided with a first successive inlet and the at least one second successive gutter is provided with a second successive inlet, wherein the basic gutter opens via the basic outlet into the first successive gutter via the first successive inlet and into the at least one second successive gutter via the second successive inlet, wherein the basic outlet and the first successive inlet are situated opposite each other and wherein the divider is so arranged that the liquid level in the basic outlet and the liquid level in the first successive inlet are equal to each other, wherein these liquid levels can vary depending on the magnitude of the flow of the basic liquid stream, wherein the first successive inlet and the basic outlet have a shape such that, in use, for each possible liquid flow in the basic gutter, it holds that the magnitude of the surface of an inlet cross section of the liquid stream through the first successive inlet, which inlet cross section lies in a plane of the first successive inlet, is a predetermined factor smaller than the magnitude of the surface of an outlet cross section of the liquid stream through the basic outlet, which outlet cross section lies in a plane of the basic outlet, so that the flow of the first liquid stream in the first successive gutter is the predetermined factor smaller than the flow of the basic liquid stream in the basic gutter.
Abstract:
A sensor (1) to determine the pressure in a milk transport system of an installation for milking animals, more particularly to determine to what extent a vacuum is present in the milk transport system. The sensor is provided with a first space (4), bounded by one first wall (2), which, in use, is in open communication with the milk transport system or is part of the milk transport system. The sensor is further provided with a first electrode (8) which is mechanically in contact with the first wall, a second electrode (12) and an electronic measuring circuit (16) for measuring a parameter which depends at least on the capacity formed by the first and the second electrode. The sensor is designed such that a distance between the first and second electrode varies as a function of a difference in pressure between the first space and the second space so that the parameter is a measure of the pressure prevailing in the first space relative to the pressure prevailing in the second space.
Abstract:
A milk meter (100) for obtaining information about the volume and/or mass of milk provided by a milking machine when milking animals. Here, the milk meter comprises at least one tubular measuring section (4) through which, in use, milk flows. The milk meter has as characteristic that the tubular measuring section (4) is provided with at least one measuring electrode assembly (8,10) for carrying out, per measuring electrode assembly, an impedance measurement on a milk volume present in the measuring section (4). Here, the tubular measuring section (4) has, at its inside at the location of the at least one measuring electrode assembly (8,10), an elongated slot-shaped cross section (9, 11) with at least two opposite long sides (12, 14) and, optionally, with short sides. Each long side of two opposite long sides (12, 14) is provided with at least one measuring electrode of the at least one measuring electrode assembly (8, 10)..
