Abstract
A milking machine detects a flow rate of milk during milking and integrates by a completion timer the time when the detected flow rate is smaller than a reference flow rate near an end of the milking, the integrated time being displayed graphically. The reference flow rate is corrected by a specific resistance of milk. The specific resistance is obtained by selecting a minimum resistance value from resistance values of milk which are actually measured during a predetermined time interval starting from a time after milking begins when a flow rate of milk measured on the basis of a predetermined standard resistance value reaches a predetermined value.
Claims6
A device for measuring and controlling flow rate of a milk in a milking machine, said device comprising:
- a pair of electrodes disposed in a milk flow line during a milking process;
- flow rate detection means for supplying a reference current between said electrodes, detecting an electrical resistance value btween said electrodes, said detected resistance value is represented a measured flow rate of milk, and from said detected resistance value developing a signal representing said measured flow rate of milk;
- time integration means for integrating an elapsed time near an end of the milking process when the measured flow rate of milk is at a diminished level;
- said time integration means including a timer for calculating said integrated elapsed time, comparing said integrated elapsed time to a predetermined elapsed time and producing a completion alarm, said timer operates in response to said signal from said flow rate detection means when said measured flow rate of milk is less than a predetermined reference flow rate;
- and
- display means for displaying said integrated elapsed time obtained from said time integration means.
