Description

technical field [0001] The present invention relates to liquid density measurement technology, more specifically, to a system, method and application for detecting liquid density. Background technique [0002] The liquid surface wave can reflect the properties of the liquid, such as surface tension coefficient, viscosity coefficient, etc. On the basis of combining other parameters, the density of the solution can be measured indirectly. Among them, there are many methods for measuring the surface tension of liquids, most of which belong to the contact method or static Methods, such as pull-off method, titration method, capillary method, maximum bubble pressure method, etc., are commonly used. The disadvantage of these methods is that they cannot be measured continuously in real time, and they will pollute the liquid. [0003] The blister manure process is used to regularly remove the manure and urine in the livestock house, reduce the labor input in the manure cleaning proce...

AI Technical Summary

Problems solved by technology

At present, the detection of excrement solution requires direct contact with the above solution, obtaining samples, and then taking them back to the laboratory for various attribute tests, which is not only time-consuming and laborious, but also has safety problems

The narrow floor drain gap in the blister manure process also increases the difficulty of sample extraction; in the new smart pig house, inspectors need to do disinfection and sterilization before entering the pig house, and must wear protective clothing to enter the pig house, which increases the detection process by changing directions Complexity; the process of soaking manure in water will cause a certain amount of ammonia pollution, which has caused great difficulties to the traditional direct contact collection and detection method, and also put forward higher requirements for the psychological quality of the collection personnel, safety protection and collection equipment
