FIELD: animal farming. SUBSTANCE: method involves providing preliminary measurements and introducing into control unit constant values of opening time topen and closing time tclose of cutoff valve, average of milk flow Qaver at transition process during closing of cutoff valve tclose upon completion of emptying process, and measurement chamber volume V0, with amount of milk delivered for one cycle being measured from formula: , where V is volume of milk pumped during one switch of milk pump, l. Apparatus has measurement chamber provided with inlet branch pipe, outlet branch pipe arranged in lower part of measurement chamber and equipped with electromagnetic cutoff valve coupled to milk pump, upper and lower level sensors arranged in measurement chamber, and microprocessor control unit with digital indication unit. Employment of electromagnetic cutoff valve allows running over of milk upon stopping of milk pump to be excluded and efficient separation of measurement chamber filling and emptying processes to be provided. EFFECT: increased efficiency and improved precision of measuring milk amounts. 3 cl, 3 dwg
