Embodiment 1

[0025] Such as figure 1 As shown, the light hydrocarbon density meter of this embodiment includes two parts: a tester and an electronic scale. Among them, the tester such as figure 1 , comprising an end cover 10, a liquid inlet barrel 60, a transparent measuring tube 50 tightly connected between the end cover 10 and the liquid inlet barrel 60, the upper end of the end cover 10 is provided with a liquid outlet communicating with the top of the transparent measuring tube 50 The exhaust port 20 and the liquid outlet valve 30 used to control the on-off of the liquid outlet and exhaust port 20, the bottom or side of the liquid inlet barrel 60 is provided with a liquid inlet 70 and is used to control the on-off of the liquid inlet 70 The liquid inlet valve 71, the end cover 10 and the liquid inlet barrel 60 are fixed by four uniformly arranged screw rods 40, and the top and bottom of the transparent measuring tube 50 are provided with O-shaped valves for preventing liquid leakage. ...

Embodiment 2

[0032] This embodiment provides a method for measuring the density of light hydrocarbons using the light hydrocarbon density meter described in Embodiment 1, comprising the following steps:

[0033] Step 1: Place the tester marked with the scale line 51 on the electronic scale to weigh, and then click the "tare" function button of the electronic scale to tare, so that the electronic scale displays zero;

[0034] Step 2: Connect the outlet of the light hydrocarbon liquefied gas to be measured to the liquid inlet 70 through a transparent high-pressure rubber hose, and open the liquid inlet valve 71 at the same time, so that the measured liquid is injected to reach the scale line, and close the liquid inlet valve 71;

[0035] Step 3: Place the tester on the electronic scale to weigh, read the mass displayed on the electronic scale, if the mass unit is gram (g), the read mass value / 1000 is the liquid density, if the mass unit is Kilogram (kg), the mass value read is the density va...

Abstract

The invention relates to a light hydrocarbon density instrument, which comprises a tester for accommodating liquid to be measured and an electronic balance with a peeling function, wherein the tester comprises an end cover, a liquid inlet bucket and a transparent burette tightly connected between the end cover and the liquid inlet bucket; a liquid outlet air exhaust port communicated with the top of the transparent burette and a liquid outlet valve for controlling the liquid outlet air exhaust port to be opened or closed are arranged at the upper end of the end cover; a liquid inlet and a liquid inlet valve which is used for controlling the liquid inlet to be opened or closed are arranged at the bottom or the side edge of the liquid inlet bucket; a plurality of uniformly distributed screws are arranged between the end cover and the liquid inlet bucket, so that the end cover and the liquid inlet bucket are fixed by the screws; sealing rubber rings for preventing liquid from leaking are arranged in the top and the bottom of the liquid inlet bucket; a scale for indicating the volume of the liquid of 1,000 ml is formed on the transparent burette; and the liquid inlet bucket has a hollow structure, and is communicated with the bottom of the transparent burette. The invention also provides a method for measuring the density of the liquid by using the light hydrocarbon density instrument. The light hydrocarbon density instrument is convenient to use, low in cost and convenient to popularize.

Description

technical field [0001] The invention relates to the field of liquid density measurement, in particular to a novel light hydrocarbon density meter and a method for measuring the density of light hydrocarbons using the light hydrocarbon density meter. Background technique [0002] At present, the density tester used to measure the density of light hydrocarbons is to put a buoyancy density meter and a glass thermometer in the sampling tube. After filling the liquid to be tested, the buoyancy density meter floats and the liquid level The scale of the density meter is the displayed density, and it needs to be placed in a constant temperature box to ensure that the density on the density meter is indicated when the temperature is 15 degrees. The price is 20,000 to 30,000 yuan, of which, the sampling tube plus the density meter will cost 3,500-4,000 yuan, which is expensive; and the calculation method is complicated, and the error is relatively large; on the other hand, the glass h...
