ULB Type glass level gauge is a local indicating instrument produced according to the principle of connector. The medium in the container was led to the glass level gauge, and the actual height of level can be read from the transparent glass. Cylinder type glass level gauge is a large-diameter glass level gauge, which is suitable for medium with high viscosity or strong bubbles. For low-temperature medium, glass level gauge can use anti-frost fins. Using the temperature gradient principle, add anti-frost fins on both sides of the window, and observe the liquid level through the anti-frost fins.

The glass level gauge is a local indicating instrument produced according to the principle of the connector, which leads the medium in the container to the external glass level gauge, and reads the actual height of the liquid level from the transparent glass.
The cylinder type glass level gauge belongs to large diameter glass level gauge, which is suitable for the medium with high viscosity or strong air bubbles.
Anti-frost fins are used for low-temperature medium. Using the principle of temperature gradient, anti-frost fins are added on both sides of the window, and the liquid level is observed through the anti-frost fins.
The upper and lower process connection flanges of no blind zone glass level gauge are all within visible range
1.Glass level gauge are all installed with safety steel balls. If the glass level gauge breaks accidentally, under the effect of the pressure difference, the steel ball seals the valve port, blocking the passage of the medium into the glass level gauge
2.The glass level gauge can realize the measurement of high temperature, high pressure, high temperature and high pressure working conditions.
3.When the medium is vapor, alkali liquor, and PH>7, add mica pads between the glass plate and the sealing pad to protect the glass plate from corrosion by the medium.
Refining: Catalytic cracking, acid-containing precipitation tank, hydrocracking, hydrodesulfurization, coking unit, crude oil desalination, sulfur recovery, catalytic reforming
Natural gas: Light hydrocarbon recovery
