Fluid flow metering device and method and milking system

Abstract

A fluid flow metering device, including a data processing device, a container for containing fluid, and a pressure sensor arranged at the bottom of the container, the pressure sensor generates a corresponding pressure signal when it is subjected to the pressure of the fluid entering the container; the bottom of the container is also set There is a lower leak, and the upper part of the container is provided with a mixed fluid inlet and a gas outlet. The data processing device collects the pressure signal generated by the pressure sensor, and generates a corresponding pressure value according to the collected pressure signal. The pressure signal generated by the pressure exerted by the fluid measures the time required for the fluid to reach the container and flow out from the lower drain at the bottom of the container, and generate the corresponding time length value, and calculate the fluid from the lower drain at the bottom of the container based on the generated pressure value The velocity value at outflow, and calculate the fluid flow value based on the calculated velocity value and duration value. The invention also provides a fluid flow metering method and a milking system.

Description

technical field [0001] The invention relates to the technical field of fluid metering, in particular to a fluid flow metering device and method and a milking system. Background technique [0002] Milk flow meters are an important tool for monitoring the milk production of individual cows. The volume or mass of milk produced by an individual cow can be measured using a milk flow meter, so a reading of the cow's milk production can be obtained when the cow is conveyed directly from the cow to the storage bucket. [0003] In the prior art, the schemes of the milk flow meter are generally divided into two categories: one is the mechanical measurement type, and the other is the calculation type of the sensor type combined with the data processing device. For example, the Chinese patent application with the patent application number of 201080052523.0 and the invention name of "milk volume meter, milk volume measurement method and milking equipment" has the patent number of "02826...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned prior art has the following technical problems: the structure is complicated, and it is difficult to clean when the milk residue covers the metering parts; multiple electrode pairs are frequently used to collect the liquid level of the fluid, and multiple electrode pairs will pollute the milk. affect milk quality
