Abstract
The utility model discloses an instrument for measuring volume of fuel in a fuel tank of an automobile. A probe 1 is positioned at the bottom part of the fuel tank 2 of the automobile. A data logic circuit of a traditional ultrasonic rangefinder is changed into a single chip computer CPU, and the single chip computer CPU is connected with an external memory C in series or in parallel. The utility model has the advantages that the utility model can accurately measure the depth and the volume of liquid in a regular container and an irregular container, and especially the depth and the volume of the fuel in the fuel tank of the automobile.
Description
The utility model relates to the liquid measure tester, adds what tester of oil mass more specifically to automotive oil tank.
At present, the fuel tank shape of various automobiles, size be owing to produce producer's difference and also be not quite similar, the automobilist from pilothouse stalk to only be the degree of depth of oil in the fuel tank and can't know its concrete oil mass.Ultrasonic range finder is made up of probe, ultrasonic ranging circuit, data logical circuit, display, and it is used for the measurement of distance.
The purpose of this utility model just provides automotive oil tank liquid measure tester, and it can measure the degree of depth of oil in the oil mass that adds in the automotive oil tank and the fuel tank exactly, and Fuel Oil Remaining in the fuel tank.
Automotive oil tank liquid measure tester, comprise probe 1, ultrasonic ranging circuit A, one-chip CPU, storer, display, its feature is in 1 bottom that places automotive oil tank 2 of will popping one's head in, change the data logical circuit of conventional ultrasonic wave stadimeter into singlechip CPU, close and give external storage of singlechip CPU serial or parallel connection.
Principle of work: this product has the function of ultrasonic range finder, can accurately measure the pasta degree of depth in the fuel tank, and the container depth direction is divided into 100 fens, is obtained the volume of its liquid by look-up table and method of interpolation.
Advantage of the present utility model is: it can accurately measure liquid depth and volume in rule and the irregular container, particularly gasoline that adds in the case to automobile and diesel oil amount are monitored, to avoid the inaccurate economic loss of bringing to driver and unit of fuel charger precision, provide the strong instrument of a monitoring simultaneously for national technical supervision department.
Accompanying drawing is a structural representation of the present utility model.
Embodiment: select one of ultrasonic range finder for use, the bottom that probe 1 is placed automotive oil tank 2 changes the data logical circuit of conventional ultrasonic wave stadimeter into singlechip CPU, and gives external storage C of singlechip CPU serial or parallel connection.
