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.

Workshop and Processing
Explain the cause and solution of the malfunction of the magnetic
baggage measuring instrument
1. Failure phenomenon: the field instrument has no display, and the
transmitter output is a constant current value; the field
instrument displays normal, but the transmitter output is fixed at
about 2.1mA, or the output is unstable.
Cause analysis: The level gauge with the above failure phenomenon
is normal at one time. It may be caused by incomplete storage of
the instrument during construction and no protective measures after
installation and installation, resulting in damage to parts of the
circuit board with poor insulation.
Solution: Replace the display board or expansion board, re-enter
the human parameters, and perform linear adjustment.
2. Trouble phenomenon: The field instrument display is consistent
with the output of the transmitter, but the instrument failure is
not good; and the range fluctuates greatly, the output is unstable,
and the linearity is poor.
Cause analysis: collision in transportation, force error in
installation, and external force on the torsion tube after
installation.
Solution: When the torsion is damaged, replace the torsion tube,
re-enter the human parameters, and adjust it to linear; in
addition, a float hook is severely bent and deformed, and it is
normal after recalibration.
3. Fault phenomenon: E2 and E3 error codes are displayed, and
sometimes the output of the transmitter will rebound sharply.
Reason analysis: due to the long interval between meter
installation and dosing, the meter is not well sealed, and the
meter is affected by humidity, rain and blisters for a long time.
For the meter with this kind of failure phenomenon, after opening
the meter cover, most of the cavity walls are Droplets or aluminum
rust
Solution: Replace the angle converter, re-input human parameters,
and perform linear adjustment.
4. Trouble phenomenon: The output and indication are incorrect.
According to different manuals, the zero point and range cannot be
adjusted.
Cause analysis: due to installation and careless adjustment
Solution: re-execute the linear adjustment.
5. Failure phenomenon: The model is inconsistent, the accuracy of
the instrument is reduced, and the transmitter of the measurement
interface is designed based on liquid level measurement.
Cause analysis: The supplier’s juice was wrong.
Solution: Replace the float, re-enter the human parameters, and
perform linear adjustment.
6. Trouble phenomenon: The instrument cannot accurately indicate
the liquid level, and the output of the instrument changes slowly
with the liquid level.
Cause analysis: Because the steam of organic materials condenses or
becomes thicker at the connecting rod mechanism and upper and lower
limit blocks of the instrument
