Main Components of Magnetic Flap Level Gauge
The magnetic flap level gauge consists of three main components: a float (main duct), a magnetic float, and a magnetic flap column (magnetic flap indicator). It is also equipped with an indicator, a drain valve, and a connecting flange.
General Features and Advantages
The magnetic flap level gauge is user-friendly and offers multiple functional advantages in industrial liquid level measurement.
Passive Measurement Principle Without External Power
The float serves as the sensing element. Magnetic steel drives the flip indicator, allowing the gauge to operate without any external power or energy assistance.
High Safety, Sealing Performance, and Reliability
The magnetic flap liquid level gauge operates safely and reliably. It features excellent sealing and leakage prevention, making it suitable for harsh working conditions such as high temperature, high pressure, and strong corrosive environments.
Wide Compatibility and Industrial Applicability
Due to its strong compatibility, the magnetic flap level gauge is widely used in industrial production. It is an ideal solution for level measurement in tanks and various types of containers.
Adaptability to Complex Site Conditions
Industrial site conditions can be complex. Different types of magnetic flap level gauges are available to ensure accurate and stable measurement under varying operating environments.
Classification of Magnetic Flap Level Gauges
According to different standards and application requirements, magnetic flap level gauges are available in the following types:
-
Standard type
-
Economic type
-
Plastic type
-
Lining type
-
Explosion-proof type
-
Insulation type
Each type has its own specific features and application advantages.
Plastic Type Magnetic Flap Level Gauge
The plastic type magnetic flap level gauge is a commonly used anti-corrosion level gauge. Its weight is only about one-fifth that of a standard magnetic flap level gauge with the same measuring range, making on-site installation easy and efficient.
The Flap-11C plastic magnetic flap level gauge is suitable for:
-
Power plant chemical water treatment
-
Sewage treatment
-
Printing and dyeing industries
It can also measure acidic media that are compatible with PVC or PP materials.
Economic Type Magnetic Flap Level Gauge (Flap-11S)
The Flap-11S economic magnetic flap level gauge is made of 304 stainless steel and performs well in most working conditions. It is suitable for measuring slightly corrosive liquids, with cost-effectiveness being its most prominent feature.
The float is made from a high-quality seamless stainless steel tube with a diameter of 51 mm. This structure avoids common issues found in ordinary pipes, helps prevent leakage, extends service life, improves pressure resistance, and enhances overall product reliability.
Lined PTFE Anti-Corrosion Magnetic Flap Level Gauge (Flap-11P)
The Flap-11P lined tetrafluoroethylene (PTFE) magnetic flap level gauge is designed for measuring highly corrosive liquids, including strong acids, strong alkalis, oxidizing agents, and organic solvents.
It is widely used in the following industries:
-
Chemical processing
-
Oil refining
-
Storage systems
-
Transportation
-
Water treatment
Explosion-Proof Magnetic Flap Level Gauge
The explosion-proof magnetic flap level gauge is suitable for transmitting electrical signals over long distances in hazardous, flammable, and explosive environments.
Equipped with a magnetic switch or remote transmitter, it can provide high- and low-level alarms and enable real-time remote monitoring and control of liquid levels.
Thermal Insulation Type Magnetic Flap Level Gauge
The thermal insulation magnetic flap level gauge can be customized according to specific user requirements. Available insulation and heating options include:
-
Vacuum jacket type
-
Steam jacket type
-
Hot water heating type
-
Jacket cooling type
-
Electric heat tracing
-
Thermal insulation cotton
This configuration is ideal for measuring high-viscosity liquids, media that tend to solidify in winter, and both low- and high-temperature liquids.
