    A1: What is a density meter used for?
    Q1: Density meters are instruments that measure the density of a sample liquid or gas. Digital density meters are used in the pharmaceutical, petroleum, chemical, and food and beverage industries for quality control and in research and development.

    A2: How does a fork density meter work?
    Q2: The Fork Density Meters use vibrating fork technology to measure density directly, and can be used in process control where density is the primary control parameter for the end product or as an indicator of another quality control parameter, such as %solids or %concentration.

    A3: How to use a density meter?
    Q3: Density meters work by measuring the oscillation of a glass tube that contains the sample. There are digital density meters that can measure specific gravity and refraction index as well as the density of a sample.

    Tips: What is a tuning fork density meter?

    The tuning fork density meter is designed according to the vibration principle of components. This vibration element is similar to a two-tooth tuning fork. The fork body vibrates due to a piezoelectric crystal located at the root of the tooth, and the vibration frequency is detected by another piezoelectric crystal. The fork is stabilized at the natural resonant frequency by phase shifting and amplifying circuits. When the medium flows through the fork, the resonant frequency changes due to the change of the quality of the medium. Tuning fork density meter can be directly installed on storage tanks and pipelines, and its measured fluid viscosity can be as high as 20,000cP, which is a significant feature that is superior to other similar products, and it also has a very high performance-price ratio.
