Description
Technical field
Present disclosure relates to the measurement apparatus of cryogen.
Background technology
The content of this part provide only the background information related to present disclosure, and which may be not
Constitute prior art.
Generally, using measurement apparatus, such as flowmeter (this flowmeter can be Coriolis
Flowmeter, ultrasonic flowmeter or electromagnetic flowmeter) to sealing conveying liquid cryogen or
Medium, such as at ambient pressure the liquid nitrogen of deep cooling to -196 DEG C, deep cooling is to -162 DEG C at ambient pressure
Fluid behaviour (for example, the quality stream of LNG (liquified natural gas), liquefied petroleum gas and liquid oxygen etc.
Amount and/or volume flow and/or density and/or temperature) when measuring, as flowmeter is in ring
In the air of border, thus there is heat via flowmeter and pipeline with surrounding air and hand in cryogen or medium
Change, this can make, and cryogen or medium absorb heat from surrounding air and its temperature can rise therewith
And gasify, this causes cryogen to assume the state of gas-liquid two-phase when flowmeter is flow through and make
Its density reduces, and this further causes measurement result, the density of such as fluid or mass flow or volume
There is deviation in flow.Additionally, be connected in the junction at flowmeter and its two ends and with flowmeter
Pipe surface occurs frost.
In addition, it usually needs the flowmeter in fluid pipe line carries out periodically checking and calibrating,
To guarantee that flowmeter provides the flow measuring data in the range of specific required precision.Generally, pass through
By in proving flowmeter (that is, being calibrated to the flowmeter of predetermined accuracy requirement) and fluid line
Flowmeter series connection and make the cryogen in fluid line sequentially pass through flowmeter to be calibrated and
Proving flowmeter (also referred to as flowmeter calibrating installation) and simultaneously carry out flow measurement to calibrate stream
Flowmeter in fluid line.
However, when using flowmeter calibrating installation, as which is in the feelings being connected in fluid line
Also surrounding air is exposed under condition, thus the cryogen in fluid line is flowing through flow meter calibrating
During device also there is heat via flowmeter calibrating installation and fluid line with surrounding air in cryogen
Exchange, this can also make cryogen absorb heat and its temperature from surrounding air can be therewith rising
Gasify, this causes cryogen also to assume gas-liquid two-phase when flowmeter calibrating installation is flow through
State and reduce its density, this further also causes the measurement result of flowmeter calibrating installation to occur partially
Difference, most causes the calibration of the flowmeter in flowmeter calibrating installation fluid pipe line to occur partially at last
Difference, so that affect the calibration result (or meter flow calibration factor) of the flowmeter in fluid pipe line.
Additionally, being connected in the junction at flowmeter calibrating installation and its two ends and with flowmeter calibrating installation
Fluid line surface there is frost.
Thus, there is the measurement that there is more high measurement accuracy or more high measurement accuracy to cryogen
Flowmeter in device and fluid pipe line has higher calibration accuracy or higher calibration accuracy
Flowmeter calibrating installation demand.
