The Elcometer 2290 Daniel Flow Gauge is a simple gauge used to conduct flow measurement of thick or paste-like materials, such as paints or printing inks.
To determine flow measurement, the product is poured into the semi-cylindrical reservoir. When the instrument is lifted vertically, the product runs on a graduated plate, which is fixed perpendicular to the reservoir.
The distance covered in a pre-determined time is the measure of the fluidity.
