The second / level of the first and second closers is, if necessary, simultaneously influencing level switch, which is connected to a second time switch. 13. The apparatus according to claim 2, characterized in that in front of the liquid pump, which can also transport gas to a sufficient extent, a second pump is added to the liquid discharge line. f -3- "Erfindung The invention" relates to a method for degassing a "limited volume of liquid to be measured during transportation of the liquid from a liquid storage container to a liquid collection container, the liquid being withdrawn from the liquid storage container and being fed to a gas separation vessel, and, if necessary, at the same time as the supply to the gas separation vessel, the liquid is withdrawn from the gas separation vessel and fed to a liquid collection container via a volume flow meter, and at least the removal of the liquid from the gas separation vessel via the liquid flow meter to the liquid collection container is dependent on the pressure in the gas separation vessel is made. Such a method is known from the Dutch patent application Jö.OjkSJ. In the known method, the removal of liquid from the gas separation vessel is essentially controlled by a primary pressure maintained in the gas separation vessel. The purpose of the invention is to provide an improved method with which it is possible to carry out quantity measurements more precisely, particularly in the case of applications with a so-called "traveling Mi I collector", the payment to the rancher directly dependent on the measured quantity of milk. The invention is characterized in that the supply and removal of the liquid to the gas separation vessel or from it is made dependent on a negative pressure maintained in the gas separation vessel. The method according to the invention makes it possible that in the separation The invention also relates to a device which is suitable for carrying out this method, the gas separation vessel having a liquid to be connected to the liquid storage container its supply line, one via the liquid flow meter and then a first seal with the liquid collection container. to the connected liquid discharge line and a gas discharge line containing a second sealer, and a bottom part connected to the liquid discharge line, with a cross section which is greatly reduced in relation to that of the upper part to which the liquid supply line is connected, one to the liquid level in the bottom Partially reacting, influencing the level of the first and the second closing device and connected to a first time switch, as well as a control element reacting to the higher liquid level located in the separation vessel, which device is characterized in that in the liquid discharge line after the the first closing device is a liquid pumping device which can also transport gas to a sufficient extent, the suction side of which is also connected to the gas discharge line containing the second closing device, and the control device a second one The status of the first and second closers is, if applicable, a simultaneously influencing level switch which is connected to a second time switch. A liquid pumping element which can be used in the device according to the invention is e.g. the Jabsco pump, marketed by ITT, which is equipped with a liquid drive element made of a rubber material. In normal use, such a pump is self-priming up to a height of about 5 m, and even about 7 m if it is previously filled with the liquid to be pumped. However, other liquid pumps, such as displacement pumps, which can transport gas, such as air, to a sufficient extent, can also be used within the set-up followed in the device according to the invention. The invention is explained in more detail with reference to the drawing. The exemplary embodiment shown in the drawing can expediently be used in a "moving milk animator". It concerns here a tanker truck, with which the milk collected in the livestock farms and mostly stored in chilled milk tanks is collected according to a specific duty schedule and transported to the dairy factories for further processing. The volume registered with the tanker while taking the milk is a basis for the remuneration to be paid to the rancher. An accurate measurement is therefore crucial. In the drawing, a gas separation vessel is shown at 1. With 2, the line for supplying the milk to the gas separation vessel is indicated, the line 2 can be coupled gas-tight with the hose 3 in a manner not shown with the milk storage container on the farm. On the underside, the gas separation vessel, which tapers sharply towards the bottom, is provided with the Mibahahleitung line k, which via the flow meter 5 »the closure 6, which e.g. can be an electrically actuated closing device, and the pump 7 is connected to the milk collecting container 8 available on the tank truck. The pump 7 is also arranged on its suction side via the gas discharge line (air discharge line) 12 with a closure 11, which is preferably also electrically operable. At two different levels, namely in the narrow bottom part and the wider upper part of the gas separation vessel, two level switches lh and 13 are arranged, which are each connected to first and second time switches, not shown. The level switch 1¾ reacts to the level 17 of the milk in the gas separation vessel 1 in the sense that a minimum supply of milk, as indicated by the milk level 17, is always maintained in the gas separation vessel 1. The level switch 13 reacts in an analogous manner to a maximum supply of milk maintained in the gas separation vessel 1, as indicated by the milk level 16. is. The effect of the device according to the invention according to the embodiment shown in the drawing can be described as follows. After the hose 3 is connected to the milk storage container on the farm, the pump 7 is switched on. At the beginning of the pumping process, the minimum supply of milk up to level 17 is located in the gas separation vessel 1, while the closure 6 is closed -6- ·! and the closing device 11 is open. In this combination of the levels I of the closers 6 and 11, the pump 7 is the gas separation vessel 1; Withdraw air and create an oppression in it. Milk is supplied to the gas separation vessel via the hose 3 and the milk supply line 2. When the "minimum level 17" rises, the level switch 14 switches on the first timer, the function of which will be explained later. The rising milk level finally reaches the level switch 13 with which the seal 6 is opened and the seal 11 is closed. Under the influence of the suction effect Milk is now withdrawn from the pump 7 from the gas separation vessel 1, and pumped into the milk collecting container 8 via the check valve 9 and the closing device 10 while simultaneously measuring the volume in the flow meter 5. When pumping milk from the gas separation vessel, milk is of course still fed to this vessel. If, during this phase, an additional amount of air with the milk supplied is temporarily fed to the gas separation vessel due to unexpected circumstances, this has the consequence that the maximum milk level drops, as a result of which the level switch 13 is activated and the closure device 6 is closed ossen or the closer 11 i is opened. The additional amount of air supplied is then sucked out of the gas separation vessel by the: pump 7 and the milk level rises again until the level switch 13 opens and closes the two closers 6 and 11 and the milk removal from the gas separation vessel is continued again. When the milk storage container has been sucked empty, a large amount of air is suddenly fed through the hose 3 and the line 2 to the gas separation vessel. As a result, the milk level in the gas separation vessel drops to a considerable extent, so that the second time switch is put into operation in addition to the closing of the closure 6 and the simultaneous opening of the closure 11 under the influence of the level switch 13. During this period, the milk residues still present in the milk storage container and in the hose 3 are fed to the gas separation vessel. After the time set by the second time switch has elapsed, the closing device 6 is opened again and the closing device 11 is closed again, before the 'milk' present in the gas separation vessel is drawn in again. If the milk has reached the minimum level 17, the level- · -T- »switch I1! for the closing of the closing device 6 and the opening of the closing device 11 And the cycle "is finished. The first timer connected to the Charter 1¾ level has as a puncture that when the milk is sucked from the milk * 'container like this the quantity of milk supplied to the gas separation vessel is insufficient to allow the milk level to rise to the level switch 13, after the time set by the first time switch has elapsed, the seal 6 is opened and the seal 11 is closed, if the flow resistance increases when a certain volume meter 5 is used is high and as a result the capacity of the system is too low, or it is desired for some other reason that the pumping capacity with respect to the milk to be pumped from the gas separation vessel is increased, this can be achieved in that before or after the puncture 7 a second pump is added to the discharge line ^, which is connected in such a way that s It preferably takes effect when the milk level is above 16. The device shown in the drawing contains provisions by means of which the system, in particular the milk collecting container 8, can be cleaned. A switch (not shown) can be used to deactivate the level switches 1 ^ and 13 and to open and close the closers 6 and 11. Furthermore, the closing device 18 is opened and the closing device 10 is closed. The hose 3 is connected to a storage container. in which cleaning fluid is connected. The pump 7 is started and this pumps the cleaning liquid through the hose 3, the gas separation vessel 1, the knife 5 »the check valve 9» the closing device 18, the line 19 and one or more spray balls 20 into the milk collecting container 8, which together with the whole pipe system is cleaned. Of course, changes can be made to the embodiment of the device described above and shown in the drawing without exceeding the scope of the invention. For example, the electrically operated level switches, which can be rotary switches, or the air-operated closers 11 and 6 are replaced by organs acting in an analogous manner.
