Digital Viscometer Based on Arduino Uno: Innovation Measurement of Fluid Viscosity

Introduction

Viscosity, or thickness, is an essential trait in various fields, ranging from the manufacturing industry to the world of health. Accurate measurement of viscosity is crucial to ensure the quality of the product and the smooth process. In this article, we will discuss the design of a digital viscometer based on Arduino Uno that utilizes the falling ball method. This innovative device has the potential to revolutionize the way we measure fluid viscosity, providing accurate and efficient results.

Background

Viscosity is a measure of a fluid's resistance to flow. It is an important parameter in various industries, including the manufacturing of paints, inks, and cosmetics. In the medical field, viscosity is crucial in the development of pharmaceuticals and medical devices. Accurate measurement of viscosity is essential to ensure the quality of the product and the smooth process.

The Falling Ball Method

The digital viscometer works based on the principle of the falling ball method, which measures the time needed by a ball to fall through the liquid tested. This principle is based on the Stokes equation, which connects the falling time, the diameter of the ball, the density of the ball and the liquid, and the viscosity of the fluid.

Design and Implementation

The digital viscometer was successfully constructed and tested using three types of liquids: glycerin, Shell Advance AX5 oil, and tropical cooking oil. The measurement results show the viscosity value of glycerin of 12,261 Poise, Shell Advance AX5 oil of 4,302 poise, and tropical cooking oil of 1,499 poise. These results are compared with conventional methods that produce glycerin viscosity values of 12,013 POISE, Shell Advance AX5 oil of 4,496 poise, and tropical cooking oil of 1,496 poise. The relatively small difference between the results of the digital viscometer measurement and the conventional method shows the accuracy of the digital viscometer designed.

Advantages of Digital Viscometer

The digital viscometer has several advantages compared to conventional methods, including:

Automatic

The measurement process is carried out automatically, reducing the potential for human error.

Faxen Correction Factor

To increase the accuracy of measurement, this digital viscometer design has included faxen correction factors. This correction factor is obtained from the O'Seen equation, and is used to take into account the influence of the walls of the container on the falling ball movements.

Android Smartphone as a Display

The digital viscometer is connected to an Android smartphone, which serves as a display for the measurement results. This allows users to monitor the measurement process and view the results in real-time. The Android smartphone also enables users to set up the viscometer and adjust the measurement parameters remotely.
