Abstract: Liquid is cooled in a batch mode. A batch of liquid is circulated in a cooling loop (12) until it is cooled to a desired temperature at which time it is removed from the cooling loop (12) and a new batch is introduced therein. Preferably, the cooled batch is discharged from the cooling loop by the new batch with as little mixing as practicable. The cooling loop has a desired volume determined by a receiver (36) of suitable capacity. A supply accumulator (14) is used to accumulate liquid to be cooled and from which liquid to be cooled is supplied into the cooling loop. Cooled liquid is discharged from the cooling loop into a product accumulator (16). The liquid may be cooled to a temperature close to its freezing point by freezing a minor portion of the liquid in the cooling loop which is then melted by the liquid of the next batch when it is introduced into the cooling loop. The cooling loop is such as to promote plug flow and to reduce backmixing.

The liquid may be turbulent and contain bubbles of gas. In a preferred embodiment, the flowmeter includes an electrical circuit and a flow vessel which is connected as a segment of the conduit conveying the liquid. The vessel is provided with a valved outlet and is partitioned by a vertical baffle into coaxial chambers whose upper regions are vented to permit the escape of gas.

Lower zones of the two chambers are interconnected so that the downflowing liquid establishes liquid levels in both chambers.

Abstract: A device for pneumatically scanning the level of liquid in a container, such as small housings for electronic components which are to be filled with casting resin, has a pneumatic scanning nozzle disposed above the component housing for directing an extremely low pressure air stream at the liquid surface in the housing. The nozzle has a branch conduit leading to a piston movable to actuate a proximity switch for providing a signal to cease the supply of liquid to the container. When a pre-determined liquid level is attained in the container, the back pressure through the conduit moves the piston against a spring bias to actuate the proximity switch. The liquid level is thus determined in a contact-free manner so that the measuring system remains untouched by the casting resin.
