FIELD: mechanical engineering, electrical engineering, instrumentation engineering, medicine; metering out of liquids, oils, varnishes and solvents. SUBSTANCE: housing of device with threaded hole in bottom is furnished with metering tube in wall of which metering hole in form of vertical or inclined through cut is made at the level of housing upper edge. Metering tube has handwheel in the form of cylinder with horizontal scale on its surface and is provided with drop making funnel. Pointer-indicator with vertical scale is mounted on outer surface of casing. EFFECT: increased accuracy of liquid dispensing in devices provided with upper edge of housing to form free surface of liquid and drain pipeline by placing drain hole directly under liquid level; simplified design. |
