Definitions
- the invention relates to a device for reproducible, verifiable determination of the content of a tank chamber of a multi-chamber tank vehicle, such as semi-trailers, motor vehicles, trailers and the like. like.
- Tank vehicles are available in different designs, and it is known to design tanks of tank semitrailers as so-called triple wedge containers. There are different design options from the transition of the front, usually smaller sized container part to the larger rear container part, for which a connecting cone is used.
- Such tank semitrailers and also other mobile tanks are divided into individual chambers by partitions and baffles, the filling and emptying of these chambers being carried out from the underside of the tanks via corresponding nozzles and fittings. In particular, inspection covers are provided on the top.
- tank vehicles One problem with such tank vehicles lies in determining as precisely as possible the quantities of content delivered from the tank segments, which ultimately have to be paid for by the consumer. To achieve reproducible values, care is taken that external influences, such as the inclination of a vehicle, do not influence the measurements.
- this object is achieved in accordance with the invention in that a locating tube with a reference tube and an ultrasonic sensor is arranged in the geometric center with respect to the transverse and longitudinal directions within each tank chamber.
- the invention makes use of the possibility of an ultrasonic measurement to determine the content, the measuring tube used for the measurement being arranged within a tank chamber in such a way that inclined positions do not significantly distort the measurement in order to maintain the calibration capability of the system. At the same time, the invention enables reliable overfill protection.
- DE-27 17 133-A1 shows a light rod with a scale in the center of motion of a tank for level indication.
- the senor is equipped with electronics for evaluating the measurement pulses
- the electronics are equipped with an optical display of the measurement values and / or a measurement value printer.
- the invention provides in a further embodiment that to prevent fluctuations in the fill level within the individual chambers, the chamber partition walls are designed as normally curved floors in cylindrical tanks or in case-shaped tanks as essentially double-S-shaped floors.
- FIG. 1 is an outline of a sectional drawing of a tank according to the invention with a tank chamber and the indicated measuring device according to the invention
- Fig. 2 is a sectional drawing in the area of attachment of the device according to the invention and in the
- Tanks designs as semi-trailers with indicated measuring device in some of the chambers.
- a tank, generally designated 1 generally consists of a plurality of tank chambers 2, which extend from the outer skin 3 and Partition or surge floors 4 is limited, the latter in the exemplary embodiment of FIG. 1 being designed as double S-shaped floors, approximately according to the course of FIG. 3b.
- FIG. 3 to 5 in the case of FIG. 3 is a tank trailer as a triple wedge case
- FIG. 4 it is a tank trailer or trailer in cranked suitcase shape
- FIG. 5 it is a trailer in cranked cylindrical Shape.
- the device according to the invention is formed by an ultrasonic sighting tube 6 and a somewhat shorter reference tube 7 connected thereto, to which an ultrasonic sensor 8 is assigned in the region of the tank bottom .
- the sensor 8 with the dipstick 6 and reference tube 7 is fastened in a lower flange 9 and a holder 10 arranged in the dome area of the tank .
- the arrangement of the device 5 is made within the tank chamber 2 so that it is positioned in the transverse and longitudinal directions exactly in the middle of the chamber, so that inclinations of the tanker in the longitudinal and transverse directions Do not influence level measurement via sensors 8.
- the ultrasound measurement is based on the different reflection of the ultrasound pulse at the separating surfaces between the areas of different sound resistances and the registration of the transit time of the pulse from the transmission by the ultrasound sensor to the return of the reflecting pulse at the transmitter, which then acts as a receiver and is referred to here overall as sensor 8. Since the sound at each reflecting surface is only weakened by around 1%, the position of several surfaces lying one behind the other can be measured in a single pulse, which leads to a very precise measurement.
- the measurement results are evaluated by electronics 11, which is only shown schematically in FIG. 2 and which in turn displays the measurement results optically or can print them out as pressure values, which is not shown in more detail.
- 3a and 3b and 4a and 4b two differently designed tanks 1 and la are shown with double-S-shaped partitions and baffles 4 and 4a.
- 5a and 5b a tank 1b in cylindrical form is shown as a section and top view with normally curved bottoms 4b as partitions and baffles.
- 3a, 4a and 5a the measuring device 5 is drawn in each case as a double-dotted chain line in a chamber 2, 2a or 2b, here it should be noted that each of the tank chambers is equipped with such a device.
- the described exemplary embodiments of the invention can be modified in many ways without departing from the basic idea.
- the invention is not limited to one of the tank forms shown here, nor is it limited to the fact that it is a tank semi-trailer.
- tank motor vehicles can be equipped just like tank trailers and the like. Like. more.
