Abstract
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.
