Apparatus and method for filling open-ended tubes to a level below the top of the open end of the tube with a hydraulic silicone elastomer wherein a first composition and a second composition are provided to a static mixer and the mixture is supplied to the tube. The level of the elastomer in the tube is sensed by an ultrasonic sensor. When the desired predetermined level of the elastomer in the tube is reached, a signal from the ultrasonic sensor terminates the flow into the tube. The filling rate includes a fast fill rate followed by a dribble rate. The tube is vertically adjustable relative to the level sensor, and an adjustable tube stop provides a precise level adjustment.

A method for filling an open tube to a predetermined level below its open end with an admixture of two interacting compounds comprising mounting an open tube substantially vertically, with the open end of the tube facing upwardly; mixing a first and second compound adjacent said mouth of said tube; partially filling said tube with the admixture of said compounds at a first fill rate; reducing the fill rate of said admixture into said tube; ultrasonically measuring the surface level of said admixture below the open end of said tube; and terminating the flow of said admixture when the level within the tube reaches a predetermined level below the open end of said tube.
