Questions regarding the use of magnetic flap level gauges in boilers
Thread Content
Are magnetic flap level gauges used in boiler drums operating at temperatures above 300°C? How is it working?
Magnetic stones used for boiler drums are different from those used for floats; they can withstand high temperatures and pressures
Just use the magnetic flap; it’s hassle-free.
Be aware of the possibility that high temperatures may eliminate the magnetic field; if it is to be used, make sure to choose a reputable brand. In-situ glass sheets can also be used. Remote transmission meters generally include differential pressure transmitters and guided-wave radars
Firstly, high temperature and pressure can easily cause demagnetization; furthermore, the float may be damaged during startup and shutdown processes. The key is to choose a reliable manufacturer
It can be used; mica two-color magnetic flap level gauges are generally employed, and they perform well – they are usually standard equipment
High-temperature and high-pressure magnetic flap level gauges are used in a wide range of applications.
It’s intuitive in terms of two colors, but mica sheets tend to get dirty and damaged easily, resulting in high maintenance costs
Typically, the steam drum of boilers is measured using a bimetallic thermometer, an electric contact thermometer, and a differential pressure thermometer. Magnetic flap types can also be used without any problem.
Generally, glass plate level gauges are used; magnetic flip plates should be heat-resistant
