What is a float level switch?

A float level switch, while sounding simple, plays a crucial role in industrial production. Its working principle is that when the liquid level changes, the float ball rises or falls with the liquid level, triggering a switch signal to control the operation or stoppage of related equipment.

Imagine in fields like chemicals, oil, and water treatment, where the importance of liquid level control is self-evident. If the liquid level exceeds the safe range, the consequences can be disastrous. The float level switch is the "invisible guardian" protecting the safe operation of these critical equipment.

It boasts many advantages: simple structure, easy installation, high reliability, and low maintenance costs. Moreover, it can adapt to various liquid environments, whether it's clean water, sewage, or corrosive liquids.

As part of industrial automation, the float level switch, though small, plays a significant role. It silently safeguards the safety and stability of industrial production, making it our indispensable "little helper."

When to Use a Float Level Switch?

In the world of liquid storage and control, level monitoring is crucial. The float level switch serves as the "guardian" in this aspect.

When should you use a float level switch? Simply put, it's your first choice when you need to accurately monitor and control the liquid level of water, oil, chemical liquids, and so on.

The float level switch can be extremely useful in water storage tanks, fuel tanks, chemical reactors, and more. It can quickly send a signal when the liquid level rises or drops to a preset position, enabling automatic control or alarm functions.

The working principle of the float level switch is actually quite simple. The float ball rises and falls with the liquid level, and when it reaches a certain preset position, it triggers the internal switch mechanism, generating an electrical signal or mechanical action.

Moreover, the float level switch boasts a simple structure, easy installation, and low maintenance costs, making it highly suitable for long-term and stable operation in various environments.

For companies that pursue precise control and improved production efficiency, choosing a reliable float level switch is undoubtedly a wise decision.

What are the types of float level switches?

Types of float level switches are diverse and each has its unique function and applicable scenarios.

First, let's talk about the rod float level switch. It is like a dependable veteran, utilizing the coordination of a rod and a float to accurately determine the level of liquid. It is a trusted assistant for many large storage tanks.

Next, we have the cable float level switch. Its "body" is flexible and able to adapt to various complex installation environments. By combining cables with multiple floats, it can achieve multi-point level control, ensuring the safety and stability of the liquid level.

Then comes the rotary float level switch. As the name suggests, it is installed laterally and closely integrated with the wall of the container. When the liquid level changes, the float drives the rod to move, triggering a switch signal through a specific angle change, making it precise and reliable.

Magnetic float level gauge utilizes the principle of magnetic coupling to directly correlate the position of the float with the display panel. It is like a talking float, allowing us to visually see the changes in liquid level.

The magnetostrictive level switch, which sounds somewhat high-tech, actually has a close relationship with floats. Through the permanent magnet inside the float, it stimulates the magnetostrictive material inside the rod or flexible cable to expand or contract, thereby sending a switch signal to achieve precise control of the liquid level.

Each type of float level switch has its own characteristics and advantages, suitable for different scenarios and needs. They play an irreplaceable role on the path of industrial automation.
