Title: Liq. filling appts. with automatic volume compensation - ensures that constant weights are delivered and has compensator controlled by operating mechanism
IPC: G01F11/02
Filed: 1977-02-11
Abstract: The liq. filling appts. has an automatic volume compensation system compensating for temp. differences over a temp. range of 5-50 deg.C. The apparatus operates by the introduction of a separate mass into the liq., the mass being proportional to the liq. temp. The introduction of the mass into the liq. is motivated by a control mechanism which receives signals from a digital thermometer and an optical coder. The mass is in the form of a finger which is totally retractable. The appts. can be used to deliver a constant weight of liq. in a system where the sequence of filling prohibits the use of a weighing system. The liq. is contained in a tank (7) from which it passes into the cylinder (1) through the piping (12) as the piston (2) is pulled back. Simultaneously the compensator (5) is introduced into the cylinder. The compensator (5) is controlled by an operating mechanism which receives information from a digital thermometer (16) with a platinum probe (15) dipped in the feed tank (17) and an optical coder (11) which is mechanically coupled to the compensation system. The compensator (5) is moved into the cylinder by the motor (14) instigated by the control mechanism.
