    Thanks to the invention, a completely tight construction against leakage has now been achieved at the plant in question, which is probably one of the best available for measuring forest raw material on transport vehicles. The door solution and pressure piston for pressurizing a room that is currently worn out in about two years and starts to leak already after a few months, which has not been noticed and where as large errors as + / - 5% on each car stack with timber have been found. With the new door solution with pressure pistons that are intended to act against the door in its closed position and the new pressure piston construction for pressurizing the room, there is no longer any sneak leakage.
    The invention is described in more detail below with the aid of a preferred embodiment with reference to the accompanying drawings, in which fi g. 1 shows a schematic longitudinal section through a plant according to the invention, in which a vehicle with a timber load has been run in, fi g. 2 shows a similar longitudinal section showing a run-in vehicle without load, fi g. 3 schematically shows a door leaf in the closed position covering a door opening by means of a sealing frame with a seal and a number of pressure pistons intended to press the door leaf against the sealing frame in the closed position, fi g. 4 schematically shows a partial view when the sliding door leaf is slid in between the pressure pistons and the sealing frame to its open or closed position, fi g. 5 schematically shows a partial view when the door leaf is in its closed position when this is pressed against the sealing grooves by the pressure pistons, fi g. 6 shows an enlarged, schematic cross-sectional view of a plunger structure for raising the pressure in a room, fi g. 7 shows the pressure piston fi g. 6 in its uncompressed position, and fi g. 8 shows the pressure piston in its compressed position.
    The i fi g. 1 and 2 comprises a housing or housing 1, which delimits an outwardly in gas-tight closable space 2. The housing 1 has a longitudinal narrow shape and comprises doors 3 in the form of door leaves 3 ”at its two opposite short ends. These door leaves 3 ”can advantageously be made in the manner shown in fi g. 3. The doors can alternatively consist of fls of hinged joints connected to each other. Mounted in the roof of the housing 1 is mounted a disc 4 serving as a filling body, to which is connected a rectangular, bellows-like delimiting wall 5, which extends along the edge areas of the disc 4. This boundary wall 5 can be expanded vertically while maintaining a gas-tight separation between the room 2 and the outside of the housing 1. The disc 4 can be raised and lowered by means of pressure pistons 6, preferably in the form of hydraulic cylinders or similar power generators. The system also includes a device 7 for measuring the gas pressure inside the room 2. This measuring device 7 can in practice be connected to a computer equipment 7 ”for registration of various obtained measured values.
    I fi g. 1 and 2 a vehicle 8 is shown in the form of a timber truck 8 with a load 9. This load 9 may consist of a number of stacks or bundles of logs, in particular sawn logs.
    When applying the system, the vehicle 8 is first driven into the housing 1 with the load 9 attached, after which the two doors 3 are closed so that the room 2 is closed gas-tight to the surroundings. In the next step, the roof panel 4 is lowered by means of the pressure pistons 6, the panel 4 together with the bellows-shaped delimiting wall 5 successively reducing the volume of the air in the room 2; which means that in the room a certain overpressure is obtained in relation to the atmospheric pressure. When a desired overpressure has been achieved, the roof panel 4 is stopped in a given position, and the air pressure in the room is measured and registered with the aid of the equipment 7,7 ”. After this measurement and registration, the vehicle 8 is driven out and unloads the load 9, after which the vehicle 8 is again driven into the housing 1 (see fi g. 2), after which the gates 3 are closed again. In this case, the roof panel 4 is returned to its initial position. During a repeated measuring procedure, the roof plate 4 is lowered to the same position as in fi g. 1, after which the gas pressure is measured in this state. As there is no load on the vehicle, the air pressure in the room will be lower than in the measurement according to fi g. l, whereby the difference in air pressure between the state in fi g. l and the state in fi g. 2 is a measure of the fixed volume of the load 9.
    I fi g. 3 - 5 shows a preferred embodiment of a completely tight door opening 10 according to the present invention which in the example shown consists of a door 3 consisting of a slidable door leaf 3 ”from an open position to a closed position over a sealing frame 11 extending around the door opening 10. with a resilient elastic seal 12 therein.
    The seal 12 is intended to seal against the periphery of one side 13 of the door leaf 3 'after the pressure of the door leaf 3 "against the seal 12 by means of a number, against the periphery 14 of the opposite side of the door leaf 3 and perpendicular to the same, preferably pressure pistons 15 designed as hydraulic pistons. in combination with the door seal 11,12 provides a completely tight door opening 10 without sneak leakage in that they have a stand-by pressure in the closed position, whereby completely reliable measurements are feasible for at least a decade.
    Previous piston constructions, which raised the pressure in a room, suffered from wear which resulted in surreptitious leakage, which in turn affected the measurement results by up to +/- 5%.
    With the new pressure piston 6 ”according to fi g. 6 - 8 which is intended to increase the pressure in the room 2 fi there is no wear on the parts that can give rise to surreptitious leakage, Fig. 6 - 8 shows a cross-section of the pressure piston 6 ”which raises the pressure in the room 2 in relation to the atmospheric pressure. Due to its construction according to the guras, the piston is completely tight in a compressed position and remains so for decades due to incessant wear because the seal consists of a surface medium 16 which, due to its density, is tight.
    The 6 "pressure piston which compresses and decompresses the gas-tight space 2 in combination with the gas-tight door openings 10 eliminates all sneak leakage and wear by sealing with a surface medium 16, which constitutes the sealing member due to its homogeneity and light surface around the pressure piston 6" surface and where at least one pushing and pulling unit 17 in the center inside or outside the pressure piston 6 ”provides for compression or decompression to pressure chamber at the same time as pressure-relieving openings 18 are provided at the free end portion 19 of the piston 6” for 100% emptying of pressure.
    The level control of the surface medium is handled by a communicating vessel 20.
