Abstract

PURPOSE:To carry out the automatic control at a low price, by arranging one or the plural capacity detector for detecting the difference of a dielectric constant of air and liquid on a tube for absorption and vomitting and detecting the quantity of absorption and discharge from this detected output and also, carrying out the determinate quantity absorption and vomitting control. CONSTITUTION:A pair of electrode plates 47a, 47b for capacity detection is arranged on a tube for absorption and vomitting 43 so as to make the plates 47a, 47b opposed to the outside of the tube 43 each other. Said plates 47a, 47b are connected with an electrostatic capacity detector 52 for detecting the electrostatic capacity between the plates 47a, 47b through a signal wire and its detected electric power is given to a control device 51 by the detector 52 through the signal wire and then, the device 51 is connected to an operating set 53 provided for giving the designation of absorbing and discharging quantity or various establishment or indication of dispensing time through the signal wire. By such constitution, an automatic apparatus having a simple construction and carrying out a highly accurate determinate quantity dispensing, can be obtained.
