In the production process, it requires several useful tools to help facilitate the process. In addition to facilitating the production process, the tool is also useful for maintaining the quality of the dose of a product. Especially when you are struggling with liquid material. Given one of the properties of liquid objects is very easily affected by temperature. So a production that uses liquid material certainly requires a tool that can measure the level of precision of the liquid. Among the many tools for measuring fluid, a viscometer is the most important.
What is a Viscometer?
Viscometer is a laboratory tool used to measure viscosity, do not have the tools? IBS also sells laboratory equipment. Viscosity is the resistance of movement of liquid objects. High viscosity liquids will flow much more slowly than low viscosity fluids. An example is the oil flow rate compared to the water flow rate when both are at the same room temperature.
When working with liquid objects in a production, knowing the viscosity is very important. One reason is as a quality control of the liquid. If there is no viscosity control, a product cannot be guaranteed quality.
You may be familiar with Zahn’s cup, which was discovered by General Electric in 1936. Zahn’s cup is a kind of cup-shaped efflux viscometer. Here are the types of Viscomometers that you need to know:
- Viscometer hole
- Capillary viscometer
- Piston viscometer falling
- Rotational viscometer
- A falling ball viscometer
- Vibration viscometer
Why is a Viscometer Important?
A viscometer will help you ensure that the viscosity of your liquid is in the precise amount required. A viscometer will help you get consistent results. In a production, consistency is the key to good product quality.
As mentioned before, without measuring your viscosity you will experience a number of problems in measuring. The treatment of high viscosity will be different from the treatment of low viscosity. If you do not do this you may experience problems such as inconsistent color changes, excess waste, excessive use of solvents, and various other unexpected quality imperfections.
A customer certainly will not be happy with a product that has inconsistent quality. That is why it is very important to monitor the viscosity in your production process.
Capillary Viscometer and its Working Principle
In this article, we will focus on discussing capillary viscometers. Capillary viscometer is also known as U tube viscometer, which consists of a U-shaped glass tube with two balls (one higher and one lower). Capillary viscometers are categorized into three groups, namely:
- Oswald type, which in various forms are designed for clear (transparent) liquid.
- Suspended Level type, where the capillaries are useful to ensure the same air pressure, regardless of the volume of liquid that is inserted into the viscometer varies.
- Reverse flow type, suitable for opaque liquids.
Each of these categories has a number of sets of viscometers named after the discoverers. Each type of Ostwald and Suspended Level has seven types of viscometers0,2-20,000 mm2 / s dan 0,3-100,000 mm2 / s. Whereas this type of backflow has 4 sets of viscometers with a range covering up to 300.000 m2 / s.
This type of viscometer is very easy to use. The principle works, the liquid will flow from the higher ball to the lower ball through the capillaries. The viscosity of the liquid is measured by calculating how long the fluid / liquid passes through the tube. Capillary viscometer is very good for measuring the viscosity of oil type liquid.
That was a brief explanation of the viscometer, especially the capillary viscometer, which is certainly very useful for measuring the level of precision and maintaining the quality of your product. That way, you don’t need to worry about the quality of your product.
