Liquid level on.
Preceding water valve is sequentially arranged at rear water valve on the drainage channel for being connected to glass tube, and passes through experimental calibration water valve and water
Glass tube capacity between valve.It is floating to ensure since the measurement range of high-precision triangle reflection laser rangefinder is extremely limited
The position of son is present within the measurement range of laser range finder always, using front and back double water valve discharging modes：It is marked by testing
Pipe capacity between fixed two water valves, water valve before when draining first opens, makes liquid flow at rear water valve, and float is made to return to laser
In the measurement range of rangefinder, then preceding water valve closed, after rear water valve is opened, so that the liquid among two water valves is discharged, finally
Water valve after closing, float is always all in the measurement range of laser range finder when achieving the purpose that measurement.
A kind of calibration method of the calibrating installation of small volumetric(al) standards device, includes the following steps；
（1）Testing liquid is injected in connection glass tube, float is put into connection glass tube right output port, float is made to enter Laser Measuring
The measurement range of distance meter;
（2）The current liquid level of float is read by PC control laser range finder；
（3）The left port that small volumetric(al) standards device is aligned to connection glass tube carries out drain；
（4）The current liquid level of float is read by PC control laser range finder again；
（5）By host computer procedure, the liquid level difference before and after drain, then the liquid level by experimental calibration and small appearance are calculated
The relationship between the volume of standard set-up discharge liquid is measured, obtains the volume of discharge liquid, to realize small volumetric(al) standards dress
The calibration set；
（6）If the position of float has exceeded the measurement range of laser range finder, quantitative liquid can be arranged by preceding water valve, rear water valve
Go out, and ensures float still in the measurement range of laser range finder；Pass through the pipe capacity between two water valve of experimental calibration, draining
When preceding water valve is opened, so that liquid is flow at rear water valve, and float is made to return in the measurement range of laser range finder, then by preceding water
Valve close, after rear water valve is opened, so that the liquid among two water valves be discharged, finally closing after water valve, float when reaching measurement
Always the purpose all in the measurement range of laser range finder.
The beneficial effects of the present invention are：The present invention realizes the high-precision calibration for small volumetric(al) standards device, adopts
With high-precision laser range finder, it can be achieved that more accurately being calibrated than conventional method.Double water valve discharging modes, it is ensured that float
Always within the measurement range of laser range finder.
Description of the drawings
Fig. 1 is the structural schematic diagram of calibrating installation of the present invention.
In figure, it is calibrated small volumetric(al) standards device 1, connection glass tube 2, laser range finder 3, float 4, preceding water valve 5-1
