Liquid flow metering system and method

Abstract

The invention discloses a liquid flow metering system. The liquid flow metering system comprises a control system, a liquid taking module and a detection module, and the control system is used for receiving a liquid supply signal and controls the liquid taking module according to the liquid supply signal; the liquid taking module is used for providing gas and delivering liquid in a liquid storage module through gas pressure; the detection module is used for detecting gas pressure and calculating the volume or the weight of the liquid delivered according to the pressure intensity; when the volume or the weight of the delivered liquid reaches the requirement of the liquid supply signal, the control system is further used for stopping the liquid taking module from delivering the liquid. The invention further discloses a metering method based on the liquid flow metering system. The volume or the weight of the delivered liquid is obtained by measuring the pressure intensity, the volume or the weight of the delivered liquid is integrated in a pipeline where pumped gas flows liquid through the pressure intensity, a weighing sensor does not need to be additionally arranged, and the liquid flow metering system has the advantages of being compact in structure, precise to measure and simple in operating method and saving the cost.

Description

technical field [0001] The present invention relates to a liquid flow calculation system and method, in particular to a liquid flow measurement system and method applied to wine vending machines, wine dispensers or other liquid vending terminals. Background technique [0002] The automatic liquid vending machine is a kind of automatic vending machine that can discharge liquid. The existing automatic liquid vending machine includes a liquid discharge device through which the liquid is supplied to the buyer. The existing automatic liquid vending machine is sold through a load cell When the liquid is weighed, when the container for taking the liquid is not set on the load cell, the sold liquid cannot be weighed smoothly. Therefore, there are certain operating requirements for the user. Generally, consumers will The weight of the wine obtained by consumption is quite different from the setting. Contents of the invention [0003] In view of this, the application provides a liq...
