Abstract:
Boiler water level sensor is used in boilers to measure the water level
inside the boiler. Besides, it is also used to control the feedwater pump of the
boiler. The boiler water level cannot be too low or too high from the normal
level. If the water level is too low, there could be a risk of boiler tubes ruptures
or even explosion and if the water level is too high, the efficiency of the boiler
is dropped hence increasing the fuel consumption.
In the older times, there is no boiler water level sensor is used, to
measure the water level, operator needs to manually check the water level
through the sighthtglass thus increasing the risk of operator to hazardous
environment and increasing the crew needed to operate the boiler.
To educate the students about the boiler water level sensor, a teaching
aids is needed to make sure the students can easily understand the working
of the sensor. The teaching aids usually did not consist of complicated
equipment and systems like the actual, so it would help the students
understand easily.
