Choosing the Right Magnetrol Level Switch for Your Application


Are you looking for the perfect level switch for your industrial application? Look no further than Magnetrol, a global leader in level and flow measurement instrumentation. With a wide range of level switches to choose from, selecting the right one for your specific application can be a daunting task. In this article, we will explore the different types of Magnetrol level switches available and provide you with the information you need to make an informed decision.


Understanding Your Application Needs


When it comes to selecting the right level switch, it's essential to first understand the specific needs of your application. Different industries and processes require different types of level switches, and it's crucial to consider factors such as the type of liquid or solid being measured, the temperature and pressure of the process, and the space constraints of the installation area. Magnetrol offers a wide range of level switches, including float switches, displacer switches, and thermal switches, each designed to meet specific application requirements.


Before choosing a level switch, it's important to conduct a thorough assessment of your application needs. Consider the environmental conditions, the type of material being measured, and the process requirements. For example, in applications where the process fluid is highly viscous or has a tendency to coat the probe, a thermal dispersion switch may be more suitable than a float switch. By understanding your application needs, you can narrow down the options and choose the most appropriate level switch for your specific requirements.


Types of Magnetrol Level Switches


Magnetrol offers a variety of level switches, each designed to meet specific application requirements. The float level switch is one of the most common types of level switches, and it is suitable for a wide range of applications. Float switches work on the principle of buoyancy, with the float rising or falling with the level of the liquid, actuating a switch when a specific level is reached. Magnetrol's float switches are available in various materials, including stainless steel, brass, and plastics, making them compatible with a wide range of process fluids.


Displacer level switches are another type of level switch offered by Magnetrol. These switches are designed to detect the interface between two immiscible liquids or the level of a liquid in a vessel. The displacer is a suspended weight that is immersed in the liquid and is designed to float on the interface between the two liquids. When the level of the liquid changes, the displacer moves, actuating a switch mechanism. Displacer switches are ideal for applications where the process fluid is sticky or prone to coating, as they are less susceptible to build-up and fouling.


Thermal dispersion level switches are designed to detect the presence or absence of a liquid in a vessel or pipe. These switches use the principle of thermal conduction to determine the presence of a liquid. When the probe is in contact with the liquid, the heat is transferred away from the probe, which is detected by the switch mechanism, indicating the presence of the liquid. Thermal dispersion switches are ideal for applications where the process fluid is highly viscous or prone to build-up, as they are less likely to be affected by coating or fouling.


Considerations for Installation and Maintenance


When selecting a level switch, it's important to consider the installation and maintenance requirements of the switch. Different types of level switches have varying installation and maintenance needs, and it's essential to choose a switch that is compatible with the installation area and can be easily maintained. For example, float switches require adequate space above the liquid surface for the float to move freely, while thermal dispersion switches may require periodic cleaning to ensure accurate measurement.


It's also important to consider the environmental conditions of the installation area, such as temperature, pressure, and the presence of corrosive or abrasive materials. Magnetrol offers a range of level switches designed for use in challenging environments, including high-temperature and high-pressure applications, as well as applications involving corrosive or abrasive materials. By considering the installation and maintenance requirements of the level switch, you can ensure that the chosen switch is compatible with your specific application needs and can be easily maintained over time.



With a wide range of level switches to choose from, selecting the right Magnetrol level switch for your application can seem overwhelming. However, by understanding your application needs, considering the different types of level switches available, and evaluating the installation and maintenance requirements, you can make an informed decision. Whether you require a float switch, displacer switch, or thermal dispersion switch, Magnetrol has the perfect solution for your level measurement needs.


In conclusion, choosing the right level switch for your application is essential to ensure accurate and reliable level measurement. By understanding your application needs and considering factors such as the type of material being measured, the environmental conditions, and the installation and maintenance requirements, you can select the most suitable level switch for your specific requirements. With Magnetrol's extensive range of level switches and expertise in level measurement instrumentation, you can be confident in finding the perfect solution for your application.
