Iranian Scientists Produce Anti-Corrosion Viscometer
“The HPHT anti-corrosion viscometer is a small device designed to measure the rheological properties of oilfield fluids and acids. This device includes several innovations that meet the needs of the industry, including ease of use, improved measurement technology, temperature performance, and ease of servicing,” said Mohammad Keramati, a technologist at the knowledge-based company.
"We were able to produce the viscosity device which was required by Sharif University of Technology," he added, noting that the product can measure the viscosity parameter at high temperature and pressure and has a high advantage over foreign samples because of its lower price.
"This device was manufactured for Sharif University of Technology but other industries like oil, petrochemicals, etc. can also benefit from it."
A viscometer is an instrument which is used to measure the viscosity defined as “the resistance to flow or shear” of a fluid. Fluids can be categorized into two types; firstly, there are Newtonian fluids which possess low molecular weights and their viscosity is independent of time and shear rate, and thus depends only on temperature, pressure and molecular properties. Secondly, non-Newtonian fluids are of high molecular weight, possessing a variable viscosity depending on the strain rate.
In different industries, viscosity is one of the key parameters which need to be measured to control the process of dipping and coating of the fluids, resulting in a better quality of the product. The real-time monitoring/measuring the fluid viscosity is important particularly in the case of industries associated with syrups and lotions, thus it is critical to monitor batch consistencies and quality control of manufactured substances before getting it into public hands.
Plastic industries as well, rely on viscometers to characterize the plastics’ dimension, strength and other required specifications before manufacturing it, because measuring viscosity parameters of the plastics help the manufacturers to understand the physical and chemical properties especially when they are treated at different temperatures during production.
