Feeder device of samples for vibrating tube electronic densimeters.

摘要

A sample feed device for vibrating tube electronic densimeters, of the type comprising a measuring cell (1), provided with a charge port (2) and a discharge port (3). The device comprises a heat-insulated block (4) provided with an upper port (5) and a lower port (8) communicating over passages (6) and (9) with charge and discharge (10) ports capable of being engaged with the corresponding ports (2) and (3), there being provided a suction chamber (11) having an inlet port (12) connected to the port (8) and an open end (13), fitted to a collector container (14), provided with a suction port (15) connected to suction means (16). The block (4) and the cell (1) are held at a constant temperature throughout the test. Applicable to the determination of the density of highly viscous products such as bitumens. <IMAGE>
