Abstract
The utility model discloses a tank liquid level measuring device, which comprises a pressure sensor arranged at the bottom of a tank, wherein the pressure sensor is connected with a data processor. The pressure sensor is arranged at the bottom of the tank, and P is equal to rhogh, wherein both the density rho and the gravity constant g are constants, and the height h of the liquid level is in proportion to the pressure P; and the proportional relation between the liquid level height and the pressure value is measured through experimental data, the pressure sensor transmits the measured pressure data value to the data processor, and the data processor calculates the liquid level height corresponding to the pressure value according to the proportional relation between the pressure value and the liquid level height. Because the liquid level pressure value is only related with the liquid level height and the measurement result of the liquid level pressure value is not affected by greasy dirt impurities, the measurement accuracy is high, error alarm operation can be avoided, and the production efficiency is improved; and in addition, a communicated tubule is not needed in the measurement process, so the device has relatively simple structure.
Description
Technical field
The utility model belongs to field of sensor measurement, is specifically related to a kind of liquid level emasuring device that is used for the emulsion tank body.
Background technology
Emulsifying agent is owing to have cooling, lubricated, cleaning, effect such as antirust, is widely used in can causing rotten formation industrial waste water after using in the production processes such as cold rolling, the broaching, fraising, polishing of steel plant, smooth, cutting.Because it contains more oily substance, must remove emulsion before its discharging and handle.Removing the emulsification flow container is exactly to carry out the container that emulsion is handled, and except that on the emulsion tank body liquid level sensor being installed, the liquid level in it is monitored, and when liquid level reaches the value of setting, sends alerting signal, notifies the staff in time to handle.
The level monitoring device that is adopted at present is as shown in Figure 1, each independently be provided with on the tank body 1 with tank body 1 in the tubule 2 that is communicated with, the height and the tank body 2 internal emulsification liquid 3 of tubule 2 internal emulsification liquid 3 liquid levels highly are consistent.With non-contact level sensing device 4, be installed on the tubule place such as ultrasonic liquid level sensor, photoelectric liquid level sensor etc. and carry out level monitoring, Monitoring Data directly is sent to data processor 5.This device can be monitored tank level preferably, but because oil emulsion acrobatics bonding is measured the communicating pipe inwall, influences the accuracy of measurement data.Sensor misinformation data cause false alarm, influence the treatment effeciency of oil-polluted water, and need on tank body, offer special communicating pipe, and structure is comparatively complicated.
The utility model content
The purpose of the utility model is to provide a kind of accuracy high, simple in structure tank level measurement mechanism, to increase work efficiency.
The said tank level measurement mechanism of the utility model comprises the pressure transducer that is installed on tank base, and pressure transducer connects data processor.
Preferably, said data processor is connected with display device.
Preferably, said data processor is connected with SR.
Optional, said processor is a single-chip microcomputer.
Adopt the said tank level measurement mechanism of the utility model, pressure transducer is positioned over the bottom of tank body, by P=ρ gh; Wherein density p and gravity constant g are constant; The height h of liquid level is directly proportional with pressure P, measures the proportionate relationship of liquid level and force value earlier through experimental data. pressure transducer is sent to data processor with the pressure data values that records; Data processor calculates the pairing liquid level of this force value according to the proportionate relationship of force value and liquid level.Because the liquid level force value is only relevant with liquid level, its measurement result does not receive the influence of greasy dirt impurity, measures accurately height, can avoid the false alarm operation, enhances productivity; In addition, need not offer the connection tubule in measuring process, structure is simple relatively.
Description of drawings
Fig. 1 is a tank level measurement mechanism synoptic diagram in the prior art.
Fig. 1 is the utility model structure tank level measurement mechanism synoptic diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
Like Fig. 2, the said tank level measurement mechanism of the utility model comprises the pressure transducer 6 that is installed on tank body 1 bottom, and pressure transducer connects data processor 5, and the single-chip microcomputer that this processor can be general also can be other control chip.
Pressure transducer is positioned over the bottom of tank body; By P=ρ gh, wherein density p and gravity constant g are constant, and the height h of liquid level is directly proportional with pressure P; Measure the proportionate relationship of emulsion 3 liquid levels and force value earlier through experimental data;. pressure transducer is sent to data processor with the pressure data values that records, and data processor calculates the pairing liquid level of this force value according to the proportionate relationship of force value and liquid level.A kind of in addition disposal route is that to draw liquid level earlier be zero pairing range of pressure values during with the full scale liquid level, takes the percentage of range then according to force value, is the percentage of liquid level.Because the liquid level force value is only relevant with liquid level, its measurement result does not receive the influence of greasy dirt impurity, measures accurately height, can avoid the false alarm operation, enhances productivity; In addition, need not offer the connection tubule in measuring process, structure is simple relatively.
Be better implement the utility model, be connected with display device at said data processor.This display device is charactron or LCDs etc., and the liquid level value that is calculated by data processor can directly show through display device, makes things convenient for the staff to read.
For further improving the implementation result of the utility model, said data processor is connected with SR.Can make things convenient for the staff in time to reset through SR and regulate operation, reduce its measured deviation, improve the accuracy of measuring.
More than technical scheme that the utility model embodiment is provided carried out detailed introduction; Used concrete example among this paper principle and the embodiment of the utility model embodiment are set forth, the explanation of above embodiment only is applicable to the principle that helps to understand the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, the part that on embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.
