Mechanical / Magnetic Floats Level Transmitters
Description
Mechanical and magnetic float level transmitters are devices used to measure the level of liquid within a container. They operate by detecting the position of a float, which moves up or down in response to the liquid level, and converting this movement into a readable signal.
Working Principle
Mechanical and magnetic float level transmitters work by utilizing a float that either directly interacts with a mechanical switch or uses a magnetic operation to activate a reed switch. In magnetic float systems, a permanent magnet is sealed inside the float, which rises or falls with the liquid level, triggering the switch at a specific actuation point. This mechanism is simple yet effective, making these transmitters useful for providing reliable level measurements in various settings.
Applications
Mechanical and magnetic float level transmitters are commonly used in oil-water separation systems to determine the interface level between the two liquids. They are also employed in multi-parameter sensor systems where accurate liquid level measurement is crucial.
Advantages over other Level Transmitters
Mechanical and magnetic float level transmitters offer several advantages, including low cost, simplicity, and dependability. These attributes make them a preferred choice in applications where budget constraints and reliability are significant considerations.
Limitations
One of the primary limitations of mechanical and magnetic float level transmitters is their inability to function effectively with highly viscous materials. This restriction limits their use in certain industrial applications where the fluid's viscosity is a critical factor.
Considerations
When selecting mechanical and magnetic float level transmitters, several factors should be considered. Initial costs are generally low, making them an economical choice for many applications. Operating expenses are minimal due to their simple design and low maintenance requirements. However, their accuracy may not be sufficient for applications requiring precise measurements. Durability is typically high, but replacement and maintenance costs should be factored into the overall cost of ownership, especially in environments where the transmitter is exposed to harsh conditions.

The FG Series is a magnetic float level transmitter comprising a float and sensing guide rod. The float is sized (volume and weight) based on the density of the fluid to be measured. As the liquid in the vessel travels up and down, the float will rise and fall on the sensing rod. The magnetic float... [See More]
