產品特點 產品規格

  • The SIKA oval wheel meters were developed for volume and volumetric flow measurement of liquids. They are used in applications such as lubricant monitoring or food and beverage production.

    • displacement flow meters with direct recording of the volume
    • no inlet and outlet sections required
    • high-quality construction for long service life and high reliability
    • high long-term stability
    • high measuring accuracy and repeatability
    • easy installation

    Oval wheel meters are displacement flow meters that transport defined partial volumes in individual measuring chambers. The sensor element consists of two high-precision, toothed oval wheels that are driven by the flow of the medium and roll upon each other. With each revolution of the oval wheel pair, a specific volume is thus transported. The number of revolutions is the measure of the amount of liquid passed through. The revolutions are recorded by a sensor element.
