Pressure-Driven Flow ViscoMeter

The pressure-flow viscometer measures viscosity by squeezing fluid through a standard orifice using a piston and calculating the ratio of pressure to flow rate. It is used for quality control of non-Newtonian fluids such as coatings and inks, and can simulate practical flow scenarios like blade coating and spraying.
Selection
When selecting, consider matching the sample viscosity range with the instrument's measurement range, ensuring that the shear rate covers actual process conditions. Pay attention to temperature control accuracy and sample volume requirements, and confirm that the data interface is compatible with the existing system. For materials with high levels of hard particles, choose a measurement unit made of wear-resistant materials.
