Abstract
The utility model discloses a gas-liquid-phase variable measuring device, relates the weight measurement of liquid in a container and is a device with a gas-liquid-phase (double-variable) measuring function. The gas-liquid-phase variable measuring device is structurally composed of a gas phase pressure transmitter (1), a liquid inlet (2), a variable converter (3), a base (4), a liquid phase pressure transmitter (5), a liquid outlet (6), liquid medium (7), a tank body (8), gas medium (9) and a gas inlet (10). Compared with the prior art, the gas-liquid-phase variable measuring device has the advantages of high precision, low cost, reasonable design, use convenience and the like and particularly can accurately measure the weight of liquid which needs to be stored under the protection of certain gas and in a container at certain pressure.
Description
Technical field
The utility model relates to the liquid in container weight measurement, is a kind of novel device with gas-liquid phase (bivariate) measurement function.
Background technology
The method of liquid weight mainly contains two kinds in the measuring vessel in the market: a kind of is to measure weight by LOAD CELLS; A kind of is that conversion draws weight through correlation computations by liquid level gauge.More than two kinds of methods the liquid weight measurement that container inner pressure, weight change under the environment is constantly had certain limitation: 1) when gaseous pressure changes in the container, more than the measurement data error of two kinds of methods bigger; 2) superhuge container is measured very inconvenient with LOAD CELLS; 3) different liquid level meters need be used different materials, and cost is comparatively speaking than higher; 4) use liquid level gauge also to bother very much to some container that needs regularly to clean.
Summary of the invention
The purpose of this utility model namely is to provide a kind of novel gas-liquid phase transition measuring device; when liquid in container storage need certain gas shield and jar in exist under the environment of certain pressure, the relevant index to liquid that can be simple, accurate, instant measure and also cost relatively low.
A kind of gas-liquid phase transition measuring device disclosed in the utility model, its structure comprises: gaseous pressure transmitter 1, inlet 2, variable converter 3, base 4, liquid phase pressure unit 5, liquid outlet 6, liquid medium 7, tank body 8, gas medium 9, air intake opening 10; It is characterized in that above the tank body 8 placement bases 4, gaseous pressure transmitter 1 is installed the top of tank body 8, and liquid phase pressure unit 5 is installed the bottommost of tank bodies 8, and variable converter 3 is installed in base 4 inside, inlet 2 and air intake opening 10 are arranged at tank body 8 tops, and liquid outlet 6 is arranged at tank body 8 bottoms.The principle of this device: the pressure of establishing the survey of gaseous pressure transmitter is P
1, the pressure that the liquid phase pressure unit is surveyed is P
2, the density of liquid medium is ρ, and the radius of container is R, and the pressure that produces of liquid medium is P
Liquid, F is pressure, and S is the container bottom area, and V is volume, and m is quality, h is the liquid medium liquid level
So P
Liquid=P
2-P
1
By formula P
Liquid=F/S
F=P
Liquid* S
Get F=(P
2-P
1) * S
S=π R again
2
F=mg
So mg=(P
2-P
1) * π R
2
The quality m=(P of liquid
2-P
1) * π R
2/ g
By V=π R
2-* h
m=Vρ
And then show liquid level namely: h=(P
2-P
1)/(g* ρ).
Description of drawings
Accompanying drawing is gas-liquid phase transition measuring device structural representation.
Among the figure: 1, gaseous pressure transmitter, 2, inlet, 3, the variable converter, 4, base, 5, the liquid phase pressure unit, 6, liquid outlet, 7, liquid medium, 8, tank body, 9, gas medium, 10, air intake opening.
Embodiment
Below in conjunction with accompanying drawing and concrete enforcement the utility model is further specified.
A kind of gas-liquid phase transition measuring device of the present utility model, its structure comprises: gaseous pressure transmitter 1; Inlet 2; Variable converter 3; Base 4; Liquid phase pressure unit 5; Liquid outlet 6; Liquid medium 7; Tank body 8; Gas medium 9; Air intake opening 10.Tank body 8 is placed above the base 4, gaseous pressure transmitter 1 is installed the top of tank body 8, and liquid phase pressure unit 5 is installed the bottommost of tank bodies 8, and variable converter 3 is installed in base 4 inside, inlet 2 and air intake opening 10 are arranged at tank body 8 tops, and liquid outlet 6 is arranged at tank body 8 bottoms.Gaseous pressure transmitter 1 measurement gas pressure, liquid phase pressure unit 5 is measured the common pressure of liquids and gases, then both with data transmission to variable converter 3, variable converter 3 calculates weight and the height of liquid by formula, thereby realizes the weight of liquid and the accurate measurement of height.
A kind of its processing and fabricating of gas-liquid phase transition measuring device of the present utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except the described technical characterictic of instructions, be the known technology of those skilled in the art.
