Embodiment
A kind of hydrostatic level calibrating installation based on laser displacement measurement method, category test and measuring field, is mainly used in quiet
The detection and calibration of power spirit level.Hydrostatic level is widely used, to meet the demarcation of high-precision hydrostatic level technical indicator
Needed with calibration, devise a kind of calibrating installation of hydrostatic level.
The embodiment of the present invention is described in further detail with reference to accompanying drawing.
Package unit is fixed on platform（8）On, water pump（10）Pass through fluid connection tube（2）Hydraulic fluid from water storage
Groove（1）It is extracted into aqua storage tank（6）In, aqua storage tank（6）In liquid level rise, or take out hydraulic fluid round about and make aqua storage tank
（6）Liquid level reduces.Due to hydraulic fluid connecting tube（9）, aqua storage tank（6）And hydrostatic level（7）Linker is formed, by multiple
Measure aqua storage tank（6）The height of hydraulic fluid realizes the detection and calibration to hydrostatic level.

Cross the displacement transducer of hydrostatic level（71）Measure the height of operating fluid level.
When carrying out calibration, water pump（10）By aqua storage tank（1）Hydraulic fluid through connecting tube（2）It is pumped into or pumps out to storage
Tank（6）So that aqua storage tank（6）Liquid level change.In aqua storage tank（6）In liquid level stabilizing after, read laser triangulation liquid
Level measuring arrangement（5）Reading, while read the displacement transducer of hydrostatic level（71）Reading, the reading as current level
Number.In hydrostatic level（7）Range ability in, can select multiple liquid levels carry out repeatedly with laser triangulation liquid level emasuring device
（5）With the displacement transducer of hydrostatic level（71）Reading make comparisons, so as to realize the demarcation of hydrostatic level and calibration.
The apparatus structure is simple, and accuracy of detection is high, and the demarcation and calibration that disclosure satisfy that hydrostatic level use.
