The laser liquid level measurement device has the advantages that reliability and accuracy are high due to laser ranging, the output liquid level of analog quantity can be measured, automatic control of liquid level and an alarming protection function of the liquid level can be achieved, and the laser liquid level measurement device also can be used as a standard meter for measuring liquid level.
Description
Technical field
The utility model relates to a kind of laser liquid-level measurement mechanism, and specifically the liquid level emasuring device of a kind of normality liquid or high temperature high pressure liquid storage and transfer unit, belongs to liquid level emasuring device field.
Background technology
At present, existing liquid level emasuring device as shown in Figure 1, comprises UNICOM's container 2, and described UNICOM container 2 is connected with fluid storage, transfer unit 1 by sampling line 8, by the logical light window 3 of video camera 4 remote reviewings, show the liquid level of UNICOM's container 2 inside, thereby read the indicating value of liquid level.Logical light window 3 has light source below, and light source shows by the liquid level of logical light window 3 Hou Kejiang UNICOM container 2 inside, by the liquid level of video camera 4 remote watching UNICOM container 2 inside.But liquid level is now merely able to manually watch, can not form analog signal output to liquid level control and protection system, can only be as the servicing unit of monitoring; Also the warning device that illogical light window breaks probably affects the work of video camera on the spot when window breaks, and easily causes security incident; And the indicating value manually reading has the regular hour poor, can not control in real time liquid level.
Utility model content
In order to address the above problem, the utility model has designed the laser liquid-level measurement mechanism of a kind of fluid storage or transfer unit, and by laser ranging, reliability is high, precision is high; The output liquid level of analog quantity can be realized, the automatic control of liquid level and the alarm and protection function of liquid level can be realized; Also can be used as the master meter of measuring liquid level.
The technical solution of the utility model is:
A laser liquid-level measurement mechanism for fluid storage or transfer unit, comprises UNICOM's container, and described UNICOM container is connected with fluid storage, transfer unit by sampling line, and the liquid level that makes UNICOM's internal tank and storage, transfer unit liquid level are identical; Described UNICOM container upper end is provided with logical light window, is vertically installed with laser range finder directly over described logical light window.Utilize laser range finder to measure liquid level, laser range finder is measured UNICOM's internal tank liquid level by logical light window.
Further, the output terminal of described laser range finder and fluid level control device, the liquid level analog quantity of laser range finder output enters into fluid level control device, realizes automatic control of liquid and protection warning function.
Further, the outside surface of described logical light window is provided with the sensor that breaks.
Further, described in the sensor that breaks be connected with alarm, described alarm is such as being the equipment such as audible-visual annunciator.
The utility model adopts laser measurement liquid level mode, by UNICOM's container, transmits liquid level, and laser range finder is measured the liquid level of measuring UNICOM's internal tank by logical light window, feeds back the liquid level of liquid reservoir part.By connecting pipe principle, adopt UNICOM's container to be connected with storage, transfer unit, by laser range finder, measure UNICOM's internal tank liquid level, output simulation liquid level signal, reaches the effect of measuring liquid level; The logical light window that UNICOM container is installed has the sensor of breaking, and can realize the window warning function that breaks; Laser range finder has pinpoint accuracy and reliability, and the simulation liquid level signal of its output can enter into fluid level control device, realizes the automatic adjusting of liquid level and the function that protection is reported to the police.
The utility model has the advantage of: by laser ranging, reliability is high, precision is high, within package unit reaches measuring accuracy 5mm, meet measuring accuracy requirement completely, can realize the output liquid level of analog quantity, there is automatic alarm and logical light window leak protection A.C.D., can realize the automatic control of liquid level and the alarm and protection function of liquid level, there is high accuracy and reliability, it is high temperature resistant, the feature of high pressure may be used on the high-risk container measurement liquid level of chemical industry, also can be used as the master meter of measuring liquid level, for heat power plant boiler stores, transfer unit reference-calibrating.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
