Optar, support, bearing, rotating disk, float, telescoping tube and temperature measurement module；The bearing inner race is fixed on one with rotating disk
Rise, so as to which rotating disk can follow bearing inner race to rotate；Leveling bolt is provided with the bearing outer ring, leveling bolt is with stretching
The flange at tube top end is in contact；By the leveling for rotating the complete twin installation of leveling bolt.A hole is provided with the rotating disk,
The laser launched when being worked for Hand-hold Distance Finder passes through.The support vertical installation is on the rotating pan.It is provided with support
Shell fragment, it is fixed on for Hand-hold Distance Finder on support.
Preferably, the float is placed on inside telescoping tube, can only be fluctuated inside telescoping tube with liquid level；It is described
Float profile be regular dodecahedron.
Preferably, described temperature measurement module includes being arranged at the thermometer of float lower surface, bluetooth transceiver therein and set
The Temperature Humidity Sensor of rotating disk lower surface is placed in, for measuring the humiture of air and the temperature of pot liquid in tank in real time
Degree, and host computer is transmitted measurement result to, to carry out temperature and humidity compensation to measurement result.
The beneficial effects of the present invention are：Storage tank liquid-level meter field calibration is realized, liquid level gauge in comparison method is avoided and transports
The problem of calibration result may being had an impact in defeated and installation process；The presence of telescoping tube, on the one hand prevent float not by
The problem of control may drift out laser range finder measurement range, on the other hand also make device applicability stronger, the different rule of adjustable
The liquid tank level meter, oil truck liquid level gauge etc. of lattice；The measurement result of laser range finder and Temperature Humidity Sensor can pass through indigo plant
Tooth is transmitted to host computer, easy to use；It is high by the revised calibration value degree of accuracy of humiture, outclass hand-dipping method.

Embodiment
The present invention is described in further detail with specific implementation below in conjunction with the accompanying drawings, but the present invention is not restricted to this
A little embodiments.
As shown in Figure 1, 2, 3, the present invention provides a kind of storage tank liquid-level meter field calibration device, including Hand-hold Distance Finder
1st, support 2, bearing 5, rotating disk 4, float 8, telescoping tube 13 and temperature measurement wet module, described temperature measurement wet module include thermometer
10, bluetooth transceiver therein 9 and Temperature Humidity Sensor 11.The inner ring of bearing 5 is fixed together with rotating disk 4, so as to rotating disk 4
Bearing inner race can be followed to rotate；Leveling bolt 6, leveling bolt 6 and the top of telescoping tube 13 are provided with the outer ring of bearing 5
