Embodiment Construction

[0020] This embodiment is a novel measuring cup, such as figure 1 As shown, it includes a cup body 1 and a small-diameter pipe 2, the volume of the cup body 1 is 20L, the bottom of the cup body 1 is connected with a lower cup cover 8, the top of the cup body 1 is connected with an upper cup cover 7, and the small-diameter pipe 2 runs through the cup body 1 Inside, the upper end of the small-diameter pipe 2 is located outside the cup body 1 and is tightly connected with the upper cup cover 7, the lower end of the small-diameter pipe 2 is located outside the cup body 1 and is tightly connected with the lower cup cover 8, and the small-diameter pipe 2 located inside the cup body 1 There are 20 through-holes 3 equidistant on the same side of the pipe wall. The small-diameter pipe 2 has a float 4 inside. The float 4 is a stainless steel hollow sphere. A lower contact switch is provided between the lower cup cover 8 and the lower port 9 of the small-diameter pipe. 6. The lower conta...

Abstract

The invention provides a novel measuring cup which comprises a closed cup body and a small-caliber pipeline. The small-caliber pipeline runs through the cup body; both upper and lower ends of the small-caliber pipeline are positioned outside the cup body; the pipe wall of the small-caliber pipeline positioned inside the cup body is provided with a through hole. The novel measuring cup has the beneficial effects of increasing the volume of liquid capable of being measured, reducing the pressure of the liquid for the measuring cup, improving accuracy of a measurement result and meeting the measurement requirements on large volume, low pressure and high accuracy.

Description

technical field [0001] The invention belongs to the field of liquid detection and measurement, in particular to a novel measuring cup. Background technique [0002] In the existing technology, the volume of the liquid measured by the wide-mouth measuring cup is small and the accuracy is not high, and the error is 10% to 25%. High, with an error of 10% to 30%; standard measuring cups have high measurement accuracy, with an error of 3% to 5%, but the volume of liquid that can be measured is limited, and the maximum volume that can be measured is 1000mL; the measurement error of special-shaped measuring cups such as volumetric flasks is in Between 3% and 5%, the maximum volume of liquid that can be measured at present is 1500mL. When measuring a large volume of liquid, in order to ensure the measurement accuracy, if a standard measuring cup is used for measurement, the height of the measuring cup needs to be increased, but the liquid will generate a greater pressure on the bot...
