Description
Technical field
The utility model relates to a kind of device of demarcating LNG gas filler measurer with mass method.
Background technology
At present, China does not still have national LNG measurement standard, and corresponding vertification regulation is not also put into effect, and LNG filling machine relates to trade settlement, belongs to the measurement instrument of compulsory verification.LNG gas filler measurer is to judge the whether qualified standard set-up of LNG filling machine.For the magnitude tracing (ensureing that LNG gas filler measurer is qualified) of effectively realizing, need not dismantle under the prerequisite of flowmeter, by it being demarcated with mass method simultaneously; LNG gas filler measurer is because its interface all requires to work under ultralow temperature band die pressing type, and therefore Interface design is very special, interface connection device costliness.
Utility model content
The purpose of this utility model is exactly in order to address the above problem, and a kind of device of demarcating LNG gas filler measurer with mass method is provided, and it has advantages of that save trouble and labor efficiency is high.
To achieve these goals, the utility model adopts following technical scheme:
A kind of device of demarcating LNG gas filler measurer with mass method, it comprises LNG gas filler measurer, the liquid phase import of LNG aerating calibrating installation is connected with water source by pipeline respectively with gas phase import, the liquid-phase outlet of LNG gas filler measurer is connected with cell therefor by pipeline respectively with gaseous phase outlet, each container is placed on respectively on electronic balance, described liquid phase import is connected by liquid phase flowmeter with liquid-phase outlet, and described gas phase import is connected by gas phase flow rate meter with gaseous phase outlet.
Between described water source and liquid phase import and gas phase inflow point, be provided with water pump.
Based on a measuring method of demarcating LNG gas filler measurer with mass method, concrete steps are:
Step 1: the leakproofness of testing fixture, by water source, to water flowing in device, the air in pipeline of draining, ensures that whole pipeline is full of measured medium;
Step 2: the class of accuracy of determining gas phase flow rate meter and liquid level flowmeter;
Step 3: exceed allowed band if record the error of gas phase flow rate meter and liquid phase flowmeter, adjust the calibration coefficient of LNG gas filler measurer, the calibration coefficient of the LNG gas filler measurer after adjustment is: current demarcation ÷ (1+ error ÷ 100);
Step 4: utilize pressurized air to purge the moisture in clean whole device.
The concrete steps of described step 2 are:
(2-1) according to code (JJG1038-2008) requirement, respectively by the flow of code requirement by water source to liquid phase flowmeter and gas phase flow rate water flowing;
(2-2) water respectively pipeline being flowed out is collected with cell therefor, weigh up the quality of water in container with high-precision electronic balance, the quality of passing through water that the liquid phase flowmeter of the quality of the water that electronic balance weighs up and LNG gas filler measurer and gas phase flow rate meter are read compares, and just can determine the error of LNG gas filler measurer; Repeat above operation, repeatedly measure calculating repeatability, thereby judge the class of accuracy of LNG gas filler measurer.
The beneficial effects of the utility model: utilize the utility model to meet simultaneously and do not dismantling LNG gas filler measurer, under the prerequisite of flowmeter used, can also demarcate LNG mechanism of qi calibrating installation.
