FIELD: measurement equipment.SUBSTANCE: invention relates to the field of measurement of voltage of initial shift (plasticity) of liquids in pipelines, for example milk in hoses of milking machines. The offered method of measurement of voltage of shift of milk column consists in that using one pressuriser the water column pressure h= 20 - 25 mm is pre-set in a glass vessel connected by piping with a differential water manometer and a capillary, and the capillary piping is locked by a clip, and using the second pressuriser the portion of milk is sucked into the capillary to the column length l= by 1 - 2 cm, then the pipeline is locked by a clip, the water column h= 25 - 30 mm is established, the clip is unlocked. Meanwhile, using a stop watch the time of shift of milk column tunder the action of hpressure is measured, and then the time of shift of the milk column tunder the action of the pressure his measured. The voltage of initial shift ?is determined by the formula ?=9.8(D/4l)(t?t)(t/h-t/h), where D - diameter of the capillary, mm. The device for measurement of voltage of shift of milk column contains the pressuriser connected with piping with the differential water manometer and glass vessel to which the horizontally located capillary and the second pressuriser is connected, and the piping from the vessel to the capillary and to the second supercharger is designed with a possibility of locking by a clip.EFFECT: group of inventions is aimed at decrease of labour costs and improvement of accuracy of determination of voltage of initial shift of controlled liquid.2 cl, 1 dwg |
