    Tuning Fork Density Meter for Acid Base, Digital Type

    Fork density meter for acid-base solution, selectable M20*1.5, G1/2, or NPT1/2 electrical connection, aluminum alloy shell, optional electrical connection M20*1.5, G1/2, NPT1/2. When the medium flows through the fork body of the tuning fork densitometer, the resonant frequency changes due to the change in the quality of the medium.

    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 should I pay attention to when installing a tuning fork density meter?

    • Before installation, please confirm whether the model of the instrument meets the environmental requirements of the site, such as: process pressure, process temperature, chemical properties of the medium, etc., to ensure that the instrument can be used normally after installation.
    • Generally speaking, the tuning fork densitometer can be installed in any position that needs to be installed in a horizontal, vertical or inclined manner.
    • Avoid the feeding port: When choosing the installation position of the tuning fork density meter, the measurement error caused by the installation at the feeding port should be avoided, or even damage to the instrument.
