UGD type transparent glass tube liquid level gaugeDetailed product description：

UGD type transparent glass tube level gauge is a new type of level gauge that combines the advantages of colored quartz tube level gauge, plate level gauge, and boiler level gauge. It overcomes the weaknesses of the original glass tube level gauge, such as being afraid of breakage, weak, unstable, not pressure resistant, unclear display, and low operating temperature. To a certain extent, it can replace high-temperature glass plate level gauges, high-pressure, low density magnetic flip column level gauges, and blind spot level gauges, and is cheaper than level gauges with the same characteristics. Becoming a hot topic of market attention in the new century.

Features:
Direct reading instrument, with accurate and reliable readings.
Simple structure and easy maintenance.
Combining multiple advantages of UG, UB, and UNS (UGS).
Low price.

Main technical indicators:

Working pressure of the tested medium: 1.6 (glass tube), 2.5, 4.0, 6.3 MPa (quartz tube)
Working temperature of the tested medium: -10 ℃ to+450 ℃
Material: Carbon Steel, Stainless Steel
Heat tracing steam pressure: ≤ 0.6MPa
Steam jacket joint: G1/2 "external thread

Structural principle:

The UGD type transparent glass tube level gauge is equipped with connecting flanges on both the upper and lower valves. The flange joint is welded to the measured container to form a connector, so that the height of the medium level in the container can be directly displayed on the glass tube.
Both the upper and lower valves of the instrument are equipped with safety steel balls. When the glass tube breaks due to an accident, the steel balls can block the channel under the working pressure of the container, so that the valve automatically seals to prevent the medium in the container from continuing to flow out.
The lower end of the instrument is equipped with a drain valve for sampling, maintenance, flushing, or discharging residual liquid.

Instructions for Use:
To ensure self sealing, the pressure of the medium inside the container should be greater than 0.2 MPa.
When opening the upper and lower valves, the number of rotations of the valve stem should not be less than 4 to prevent the steel ball from touching the top of the valve stem during self sealing.
