Reflex Sight Glass Boiler Water Level Gauge
Product Description
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.
Product Features:
▲The reading is clear, intuitive and reliable.
▲ simple structure, easy maintenance.
▲Durable, it is an ideal instrument for observation of the liquid
level in various medium and low pressure vessels.

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.
