Given the challenge to fill any kind of container with any kind of liquid, engineers have diligently researched hundreds of product applications—from adhesives and sealants to coatings, and chemicals and lubricants to foods and beverages—in order to design machines that will fill containers rapidly and accurately. One critical specification needed in any industrial filling application is the viscosity of the liquid. Viscosity is the measure of a liquid’s ability to resist flow. Easy-flowing, water-like liquids have low viscosity, while thicker liquids have higher viscosities.
Additional characteristics of industrial liquids include temperature, particle size, pH and degree of foaminess. Characteristics such as “lubricity” and “abrasiveness” are also taken into account to determine the best choice of nozzle configuration. The nozzle is the proprietary fixture (or “head”) that controls the flow of liquid as it streams into the container.
