Product details
□ overview
UGDThe series monochrome 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. (Overcoming the weaknesses of the original glass tube level gauge, such as being afraid of breakage, not sturdy, unsafe, not pressure resistant, unclear display, and low operating temperature). It can to some extent replace high-temperature glass plate level gauges, high-pressure, low specific gravity magnetic flip column level gauges, and blind spot level gauges. And it is cheaper than liquid level gauges with the same characteristics, becoming a hot topic of market attention in the new century.
□ Structural principle
The upper and lower valves of the instrument are equipped with connecting flanges, which are connected 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 breaks due to an accident, the steel balls can block the passage 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 liquid discharge.

□ Installation, use, and maintenance
● Installation
The liquid level gauge is a precision instrument, and should be handled with care during transportation, handling, unpacking, and installation. It should not be hit or knocked to prevent the glass tube from breaking. The liquid level gauge is manufactured according to1.5timesPNDuring pressure testing, users are not allowed to disassemble the glass tube without authorization.
● Use
After the flanges of the upper and lower valves of the liquid level gauge are installed and connected to the flanges of the upper and lower outlet pipes of the container, slowly open the upper and lower valves to allow the liquid to flush the inner wall. If there is any unclear display, it will become clear after the pressure stabilizes. When the liquid in the container is at high temperature, the glass tube should be preheated for half an hour before being put into operation to prevent the glass tube from suddenly breaking due to high temperature.
● Maintenance
After long-term use, the liquid level gauge needs to be regularly flushed and drained. First, close the upper and lower valves, then open the drain valve to empty the liquid in the pipe and close it. Then, slightly open the lower valve to allow the liquid to fill the meter body and close it. Finally, slightly open the upper valve, open the drain valve, and repeatedly flush until clean.
If a needle valve is selected during normal operation, the number of revolutions for the valve stem to exit shall not be less than4When the glass tube is damaged, ensure that the steel ball can automatically seal.
