Vertical Mounting Magnetic Float Ball Level Gauge for Industrial Tanks

The float ball level gauge is a type of liquid level measuring instrument that operates based on the principle of constant buoyancy. Its core component is a float ball that floats on the liquid surface, directly driving an internal microswitch through a mechanical structure to output a switch signal. It is mainly used for point-level control of liquid levels (such as alarms and pump start/stop), rather than continuous measurement.

Main advantages:

• Simple structure and easy installation: Easy to install and maintain, especially suitable for underground storage tanks or top installation.
• Wide application range: Can measure high-temperature, high-pressure, viscous, dirty and corrosive media, such as asphalt and wax-containing oil products.
• High reliability: No moving mechanical parts, low failure rate, suitable for long-term stable operation.
• Good explosion-proof performance: Can be used in flammable and explosive environments.
• High cost performance: Low cost, economical and practical.

Main Types and Application Forms

The application forms of float level switches are very flexible, mainly including the following types:

1. Side-mounted horizontal float switch:

   The most common form, installed horizontally on the side wall of the container through a flange. There is a lever with a fulcrum inside, with the float in the container and the other end of the lever in the switch cavity.

   • Application: Liquid level control of water tanks and oil tanks.
2. Top-mounted vertical float switch:

   Installed from the top of the container through a thread or flange, with the float vertically suspended on a rod. When the liquid level changes, the float drives the push rod or magnetic steel inside the rod to move up and down, triggering the switch.

   • Application: Deep wells, water towers, pressure tanks.
3. Small plastic float switch:

   Usually cable-type, with the switch encapsulated in the head of the float, floating with the liquid level and actuating by tilting at a certain angle.

   • Application: Pump control, small water tanks, coffee machines, water dispensers, and other household and commercial equipment.
4. Cable/chain float switch:

   The float is suspended on a winch through a cable or chain, suitable for large storage tanks, wells, and other applications with a wide measurement range.

Magnetic Flap Level Gauge vs. Float Ball Level Gauge: Core Differences Summary

Application scenarios

• Petrochemical industry: Liquid level monitoring of raw material and finished product storage tanks, reactors, distillation towers, etc.
• Water treatment and environmental protection: Liquid level control of water pools, water tanks, sump pits, sewage treatment ponds, etc.
• Food and pharmaceutical industry: Liquid level measurement that meets hygiene standards.
• Water conservancy monitoring: Water level monitoring of dams and reservoirs.
• Civil facilities: Liquid level management of water towers, hot water storage tanks, etc.

When you need to see the liquid level height at any time and anywhere with a glance, you should choose the magnetic flap level gauge. When you only need to automatically trigger an action (such as starting a water pump or sending an alarm) at a specific liquid level point (such as the highest or lowest), the float ball level gauge is a simpler and more economical choice. In actual projects, the two are often used in combination. For example, the magnetic flap level gauge is used for on-site monitoring and continuous remote transmission, while the float ball level gauge is used as a redundant safety protection for high-high and low-low liquid levels.
