Liquid Tank Reflex Type 1450mm Glass Level Gauge
Product Description
Glass plate level gauge is divided into three kinds: Transparent
type, reflection type and sight glass type. The level gauge is
mainly composed by level gauge’s body, upper valve (gas valve),
lower valve (liquid valve), drain valve, insurance steel ball and
so on. When the glass plate have some cracks or be damaged, the
insurance steel ball will automatically stop the side valve of gas
and liquid to avoid or reduce flowing. So the worker can cut off
the bottom valve to handle it. This series product is stable,
sealed and reliable, simple installation, which is ideal instrument
for detecting for liquid level in all kinds of containers with
middle or low pressure.Connecting the upper and lower flanges of
this level gauge with the upper and lower flanges of the container
to form a permeator, then the height of liquid can be directly
seen.
Structure
The glass plate type liquid level meter is designed based on the
principle of the communicator. The liquid passage formed by the
glass plate and the liquid level gauge body is connected to the
measured container through a flange or a taper pipe thread to form
a communicator, which is observed through the glass plate. The
liquid level is the same as the liquid level in the container, that
is, the liquid level.

The needle valve at both ends of the level gauge not only functions
as a stop valve, but also has the function of a check valve in the
internal steel ball. When the liquid level gauge accidentally
breaks and leaks, the steel ball can automatically close the liquid
passage under the action of the medium pressure. To prevent the
large outflow of liquid for safety protection. The level gauge can
change the material of the part or add some ancillary parts to
achieve anti-corrosion, thermal insulation, anti-frost, lighting
and other functions. Widely used in petroleum, chemical industry,
electric power, metallurgy, medicine and other fields.

Tips for installation
1. During installation, in order to ensure the function of
automatic sealing, the liquid in the container must have a certain
pressure, at least more than 0.2MPa. When the upper and lower
valves are opened, the valve stem quitting cannot be less than four
turns. When the steel ball seals the door, it does not hit the top
of the valve stem to avoid damage.
2. In the process of transportation and unpacking, we must be
careful not to encounter something harder to avoid breaking the
glass plate.
3. Also pay attention to the specifications and models, cannot
install the wrong gauge level gauge, some media on the leveler is
limited, such as some of the glass or steel plate corrosive media
cannot be used.
4. Other maintenance clean, wash and install with the glass tube
level gauge is similar
