When purpose be to reduce the error to exist liquid in liquid flexible pipe, thus ensureing the V2 that liquid product value is user input.
After described closed electromagnetic valve, the liquid in liquid supply box that described micro controller module is detected by liquid surface height sensor
Highly, the liquid height in acquired liquid supply box is scaled liquid residual volume in liquid supply box, is stored in micro controller module
Data storage cell, and in lcd touch screen display " going out liquid to finish ", meanwhile, micro controller module controls buzzer to send
The buzzer of " ticking ", reminds user to go out liquid and terminates；The liquid opening that takes through liquid outlet tank and the setting of outer case front for the user takes out
Contain liquid device, Sheng liquid device is put back to after pouring out and taken liquid platform by liquid, prepares for liquid automatic measurement next time.Take in liquid platform
Weight sensor detect after Sheng liquid device is put back into and takes liquid platform, described micro controller module judges what data storage cell stored
In liquid supply box, whether liquid residual volume takes liquid threshold value less than or equal to what micro controller module pre-set, if liquid in described liquid supply box
Body residual volume less than or equal to micro controller module pre-set when taking liquid threshold value, micro controller module control buzzer send
The buzzer of " creak ", and lcd touch screen display " residual liquid quantity is few ", remind user to supplement the liquid in liquid supply box
Body；Facilitate user to carry out liquid next time to measure.
In above-mentioned implementation process, when liquid product value V2 that takes of user input is more than the liquid supply box of data storage cell storage
During interior liquid residual volume V1, micro controller module controls buzzer to send the buzzer of " creak ", and in liquid crystal touch screen
Upper display " fluid low ", remind user's liquid supply box in fluid low to provide the liquid as V2 for the bulking value so as user and
When to liquid make-up in liquid supply box.
The above disclosed presently preferred embodiments of the present invention that is only is it is impossible to limit the rights protection model of the present invention with this
