Abstract
The utility model discloses a GPS liquid level sensor, which solves the problems of inaccurate measuring caused by that an existing GPS liquid level sensor is oscillated when a vehicle is driving. The GPS liquid level sensor comprises an upright post in which a plurality of dry reed pipes are arranged along the height direction, a magnetic floater which is up and down along the outer side of the upright post is arranged on the outer side of the upright post, an assembling disc is arranged on the upper portion of the upright post. The utility model is characterized in that the outer sides of the upright post and the magnetic floater are provided with sleeve barrels, and the lower end of the sleeve barrel is equipped and connected with non-liner buffer flow passages in and out of the sleeve barrel, the buffer flow passages are pipes which can be in an N shape, an S shape, an M shape or a spiral line shape, and can be further a baffle plate which is arranged on the lower end in the sleeve barrel, and a buffer chamber is formed between bottom boards and lateral boards of the baffle plate and the sleeve barrel. The influence of level fluctuation to the magnetic floater in an oil tank can be avoided since the sleeve barrel and the buffer device are mounted, and the accuracy of measuring is improved.
Description
Technical field
The utility model belongs to the measurement mechanism of measuring liquid level by buoy, particularly GPS liquid level sensor.
Background technology
Existing fuel level in tank sensor comprises that its inside is provided with the column of several tongue tubes along short transverse, and there is the magnetic float along its lifting in the column outside, relies on magnet conducting tongue tube, measures the height of liquid level, is provided with the assembling dish on the top of column.In the vehicle ' process, often occur jolting or the speed change situation, cause the pasta fluctuation in the fuel tank, cause the lifting in various degree of magnetic float, influence measuring accuracy.
Summary of the invention
In order to solve existing fuel level in tank sensor, following technology official documents and correspondence is proposed to the not accurate enough problem of the measurement of liquid level.The GPS liquid level sensor, it comprises that its inside is provided with the column of several tongue tubes along short transverse, there is the magnetic float along its lifting in the column outside, be provided with the assembling dish on the top of column, its special character is to be provided with sleeve in the outside of column and magnetic float, and the inside and outside non-directional buffering runner of coupling sleeve is installed in the lower end of sleeve.
Above-mentioned buffering runner can be the pipeline that is N type, S type, M type or spiral line type, also can be as shown in Figure 2, interior lower end at sleeve is provided with a dividing plate, between the base plate of dividing plate, sleeve and side plate, form surge chamber, on the side plate of sleeve, have oil supply hole, on dividing plate, have oil outlet, the some baffle plates of installation below dividing plate, some baffle plates also are installed on the base plate of sleeve, and last lower baffle plate is alternately dislocation layout mutually, forms the runner of turning back back and forth.
The xsect that column cooperates with the magnetic float can be an Any shape, as circular or non-circular.
Enter sleeve for fear of impurity, can screen pack be installed at the oil-in place of sleeve lateral wall.
Above-mentioned assembling dish is used for this liquid level sensor is installed in fuel tank or the water tank.
Because the utility model is at column and magnetic float outside installing sleeve, and the inside and outside runner of coupling sleeve is non-linear shapes, can slow down therefore that liquid fluctuating improves measurement accuracy to the influence of magnetic float in fuel tank or the water tank.
This GPS liquid level sensor can be used to measure the oil level in the fuel tank, also can be used to measure the interior water level of water tank etc.
Description of drawings
Fig. 1 is the full sectional view of embodiment 1, and its central post 2 and oil inlet pipe 1 do not cut open, and Fig. 2 is the full sectional view of embodiment 2, and its central post 2 does not cut open.
Embodiment
Narrate embodiment with reference to the accompanying drawings.
The GPS liquid level sensor, it comprises that its inside is provided with the column 2 of several tongue tubes along short transverse, there is the magnetic float 4 along its lifting in column 2 outsides, be provided with assembling dish 5 on the top of column 2, the outside at column 2 and magnetic float 4 is provided with sleeve 3, and the interior lower end of sleeve 3 is installed a conduit 1 that is the N type, and the one end communicates with the outside of sleeve 3, the other end is in the sleeve 3, constitutes snubber assembly.Two data lines and two lead-in wires are arranged on the top of column 2, and wherein two data lines connect GPS liquid level collector, and two lead-in wires connect the oil meter loop in addition.By assembling dish 5 is fixed on the top cover of fuel tank, this liquid level sensor is installed in the fuel tank.
The GPS liquid level sensor, it is that the snubber assembly of sleeve inner is different with example 1 difference, it is that interior lower end at sleeve 3 is provided with a dividing plate 8, between the base plate of dividing plate 8, sleeve 3 and side plate, form surge chamber 10, on the side plate of sleeve 3, have oil supply hole 6, on dividing plate 8, have oil outlet 7, three baffle plates 9 of installation below dividing plate 8, three baffle plates 9 also are installed on the base plate of sleeve 3, and last lower baffle plate is alternately dislocation layout mutually, forms the runner of turning back back and forth.Oil in the fuel tank through repeatedly turning back, flows in the sleeve 3 from oil outlet 7 after oil supply hole 6 enters surge chamber at last.Like this, can reduce in the vehicle ' process the influence of the impulsive force that oil produced owing to reason such as jolt, improve the accuracy of measuring sleeve 3 inner pastas.
Claims (2)
1, GPS liquid level sensor, it comprises that its inside is provided with the column of several tongue tubes along short transverse, there is the magnetic float along its lifting in the column outside, be provided with the assembling dish on the top of column, it is characterized in that being provided with sleeve in the outside of column and magnetic float, the inside and outside non-directional buffering runner of coupling sleeve is installed in the lower end of sleeve.
2, GPS liquid level sensor according to claim 1, it is characterized in that described buffering runner can be the pipeline that is N type, S type, M type or spiral line type, also can be that interior lower end at sleeve is provided with a dividing plate, between the base plate of dividing plate, sleeve and side plate, form surge chamber, on the side plate of sleeve, have oil supply hole, on dividing plate, have oil outlet, installation baffle plate below dividing plate, baffle plate also is installed on the base plate of sleeve, last lower baffle plate is alternately dislocation layout mutually, forms the runner of turning back back and forth.
