A waste heat boiler is a kind of equipment that can recover waste heat from industrial waste gas and save energy. Accurate level measurement for waste heat boilers can help improve the stability and productivity of the equipment.
At present, the commonly used level measurement methods include guided wave radar level meter and magnetic flap level meter.
In this paper, we will compare these two level meters and analyze which one is more suitable for measuring waste heat boilers in terms of measurement principle, application range, accuracy, and reliability.
A guided wave radar level meter is a kind of non-contact level measuring equipment based on microwave technology. Its measuring principle is to determine the level height through the reflection of microwave signal between medium and air.
The guided wave radar level meter is suitable for various media and has high measurement accuracy and reliability. In the level measurement of waste heat boiler, the guided wave radar level meter can control the balance of water level and steam pressure by measuring the height of the liquid level in the boiler to ensure the normal operation of the boiler.
The magnetic flap level meter is a mechanical level measuring device, whose measuring principle is to determine the level height by the up and down movement of the magnetic flap. The magnetic flap level meter is suitable for various media and has the advantages of a simple structure and low price.
In the level measurement of waste heat boiler, the magnetic flap level meter can control the balance of water level and steam pressure by measuring the height of the liquid level in the boiler to ensure the normal operation of the boiler.
In terms of application scope, the guided wave radar level meter is applicable to various media, including high temperature, high pressure, corrosive media, etc., and can adapt to the complex environment of waste heat boilers.
While the magnetic flap level meter is also applicable to various media, its application in special environments such as high temperature, high pressure, and corrosive media is restricted.
From the perspective of measurement accuracy and reliability, the guided wave radar level meter has high measurement accuracy and reliability, which can achieve high precision level measurement and is not affected by the nature of the medium. The magnetic flap level meter has relatively low measurement accuracy and reliability and is easily affected by the nature of the medium and temperature.
From the point of view of price and maintenance cost, the price of a magnetic flap level meter is relatively low, and the maintenance cost is also low. While the guide wave radar level meter price is relatively high, maintenance costs are also higher.
The comprehensive analysis above, for the level measurement of the waste heat boiler, the guided wave radar level meter is more suitable. With high measurement accuracy and reliability, the guided wave radar level meter is suitable for various media and can adapt to the complex environment of a waste heat boiler.
Although the price of the guided wave radar level meter is relatively high, its excellent performance and long-term stability can bring more accurate data to the enterprise and help its production.
