Problems solved by technology
[0002] Existing devices that utilize pressure sensors to measure the weight of liquids in irregular containers generally can only measure the weight of liquids with a fixed density. If the density of the liquid loaded in the container is not known, it is difficult to measure the weight of the liquid; for example, Italy MG2 Co., Ltd. on May 23, 2007 disclosed a device (200710103070.X) for measuring the weight of liquid in a bottle, especially a medicine bottle, capable of measuring the weight of a solution with a fixed density

The invention discloses a liquid storage tank and a liquid weight measuring method. The liquid storage tank comprises a tank body, a first pressure sensor, a second pressure sensor, a first A / D converter, a second A / D converter and a processor, wherein the first pressure sensor is arranged at the bottom of the tank body and used for measuring the pressure of the bottom of the tank body; the first pressure sensor is connected with the processor through the first A / D converter; the second pressure sensor is connected with the processor through the second A / D converter. The two pressure sensors are adopted, the volume table of the container is obtained with a simple and practical method, and the weight of a liquid in the container is obtained according to the measured density and volume; the defect that the weight of liquids used during calibration can be measured only in the prior art is overcome.
Description
technical field [0001] The invention relates to a liquid storage tank, in particular to a liquid storage tank and a method for measuring liquid weight. Background technique [0002] Existing devices that utilize pressure sensors to measure the weight of liquids in irregular containers generally can only measure the weight of liquids with a fixed density. If the density of the liquid loaded in the container is not known, it is difficult to measure the weight of the liquid; for example, Italy MG2 Co., Ltd. on May 23, 2007 disclosed a device (200710103070.X) for measuring the weight of a liquid in a bottle, especially a medicine bottle, capable of measuring the weight of a solution with a fixed density. Contents of the invention [0003] The invention discloses a liquid storage tank and a method for measuring liquid weight. [0004] The technical solution adopted in the present invention is: a liquid storage tank, including a tank body, a first pressure sensor, a second pres...
