High Precision Weight Measurement of Liquid Viscosity

Abstract

There are a variety of purpose measuring the weight with different readability and the capacity of the weighing system, such as the using in daily life, large weight measuring instrument or laboratory dedicated high-precision digital measuring instrument. This report introduces a kind of laboratory weighing apparatus, a high-precision instrument for measuring liquid viscosity. The target weighing system readability is very sensitive, at 0.1 mg, which requires every step of making this weighing device minimizes the error. Therefore, the measuring instrument needs to use high-precision sensor, 24-bit analogue to digital converter HX711, and Arduino Uno, which is a compact and lightweight Arduino series board, has the ability to store data and perform logical operations.
