Product classification and scope of use

The series of products
(1) According to the working principle, it can be divided into two types: light transmission type and reflection type, and the specific use range is as follows:
1. The translucent glass plate liquid level gauge is mainly used to observe the liquid level of opaque or colored liquids;
2. Reflective glass plate level gauge is mainly used to observe the liquid level of colorless and transparent liquid;
(B) According to the operating temperature, it can be divided into two types: ordinary type and high temperature type, and the specific use range is as follows:
1. Ordinary glass plate level gauge is mainly used in the occasions where the pressure level is less than or equal to PN6.4MPa and the operating temperature of the measured medium is less than or equal to 250 ℃.
2. The high-temperature type can be divided into: high-temperature and low-pressure type, high-temperature and medium-pressure type and high-temperature and high-pressure type, the specific application range is as follows:
(1) The high-temperature and low-pressure glass plate liquid level gauge is mainly used when the pressure level is less than or equal to PN4.0MPa, and the operating temperature of the measured medium is greater than 250 ℃ and less than or equal to 400 ℃.
(2) The high-temperature and medium-pressure glass plate level gauge is mainly used in applications where the pressure level is less than or equal to PN6.4MPa and the operating temperature of the measured medium is greater than 250 ° C and less than or equal to 400 ° C.
(3) The high-temperature and high-pressure glass plate level gauge is mainly used for the occasions where the pressure level is less than or equal to PN25.0MPa and the operating temperature of the measured medium is greater than 250 ℃ and less than or equal to 400 ℃.
(3) According to the pressure level, it can be divided into three types: low-pressure type, medium-pressure type and high-pressure type. The specific application range is as follows:
1. The low-pressure glass plate liquid level gauge is mainly used in applications where the pressure level is less than or equal to PN4.0MPa and the operating temperature of the measured medium is less than or equal to 250 ℃.
2. The medium-pressure glass plate liquid level gauge is mainly used in applications where the pressure level is less than or equal to PN6.4MPa and the operating temperature of the measured medium is less than or equal to 250 ℃.
3. The high-pressure glass plate liquid level gauge is mainly used in applications where the pressure level is less than or equal to PN25.0MPa and the operating temperature of the measured medium is less than or equal to 250 ℃.
(D) According to the use function, it can be divided into seven types: heat tracing type, frost-proof type, no blind zone type, two-color type, ultraviolet type, wide liquid chamber type and lighting type.
1. Heat tracing glass plate level gauge is mainly used in the occasions where the measured medium needs to be kept warm;
2. The frost-proof glass plate liquid level gauge is mainly used in the occasions where the operating temperature of the measured medium is -196 ~ 0 ℃ and the glass is prone to frost;
3. The glass plate level gauge without blind area is mainly used for the occasions where continuous observation is required and no blind area is allowed in the visible range;
4. The two-color glass plate liquid level gauge is mainly used for the occasion where the medium is colorless and transparent liquid and it is not easy to observe the liquid level;
5. Anti-ultraviolet type glass plate level gauge is mainly used in the occasion where the measured medium is afraid of ultraviolet light;
6. The wide liquid chamber type glass plate liquid level gauge is mainly used in the occasions where the viscosity of the measured medium is relatively large or the volume of the instrument is relatively large;
7. Illuminated glass plate level gauge is mainly used in occasions where observation is required at night;
