We have the requisite 'know how and experience' to be your partner in the selection of proper instrumentation to control your process.Īnyone beginning the process of learning to think Rheo-Logically must first ask the question, 'Why should I make a viscosity measurement?' The answer lies in the experiences of thousands of people who have made such measurements, showing that much useful behavioral and predictive information for various products can be obtained, as well as knowledge of the effects of processing, formulation changes, aging phenomena, etc.Ī frequent reason for the measurement of rheological properties can be found in the area of quality control, where raw materials must be consistent from batch to batch. This places the instrument user in a position in which his own appreciation of the flow phenomena involved, coupled with the instrument manufacturer's 'know how and experience', must be brought to bear.īrookfield was a pioneer in the development of instrumentation for viscosity measurement and data handling and a stimulus to the development of the science. Today's instruments vary from the simple to the complex: from counting the seconds for a liquid to drain off a stick to very sophisticated automatic recording and controlling equipment. The selection of the right viscometer from the scores of instruments available to meet the need of any application is a difficult proposition. There are many different techniques for measuring viscosity, each suitable to specific circumstances and materials. Rheological relationships help us to understand the fluids we are working with so that we can either know how they are behaving or force them to behave according to our needs. They know that viscosity measurements are often the quickest, most accurate and most reliable way to analyze some of the most important factors affecting product performance. Many manufacturers now regard viscometers as a crucial part of their research, development, and process control programs. Anyone involved with flow characterization, in research or development, quality control or fluid transfer, at one time or another gets involved with some type of viscosity measurement. Viscosity measurements are made in conjunction with product quality and efficiency. Brookfield deals with liquids and semi-solids. Viscosity is a principal parameter when any flow measurements of fluids, such as liquids, semi-solids, gases and even solids are made.
