  • Magnetic Flap Level Gauge

    Magnetic Flap Level Gauge

    Magnetic flap level gauge (also known as magnetic float level gauge) is developed according to the principle of buoyancy and magnetic coupling. When the liquid level in the measured container rises and falls, the magnetic float in the liquid level gauge tube also rises and falls, and the permanent magnetic steel in the float is transferred to the magnetic flip column indicator through magnetic coupling, driving the red and white flip columns to flip 180°. When the liquid level rises, the flip column changes from white to red, and when the liquid level falls, the flip column changes from red to white. The red and white junction of the indicator is the actual height of the liquid level inside the container, so as to achieve a clear indication of the liquid level.

  • Quartz Tube Double Color Level Gauge

    Quartz Tube Double Color Level Gauge

    Color quartz tube level gauge is the use of natural light in the liquid fold, reflection principle, with the help of red, green, in the measurement, the liquid phase display green, gas phase display red. Due to the large contrast of liquid and gas phase display, the instruction is clear and clear, so it is more favorable for remote operation and night inspection. Widely used in petroleum, chemical industry, electric power, metallurgy and other industries of all kinds of transparent liquid containers and boilers, such as water, gasoline, liquefied gas, liquid ammonia, propane, propylene, aromatic, acid and other oil and chemical raw materials level measurement. At the same time for the interface measurement of two different medium densities, a three-color interface quartz tube level gauge can be selected. Three-color interface quartz tube level gauge is designed by using the principle of buoyancy and gravity difference, quartz tube in the small float suspended in two kinds of medium part of the boundary, because the float is black, the upper and lower part of the liquid level color is different, so the display eye-catching. The problem of indistinguishable interface between two kinds of mixed media in petrochemical production
