Level Sensor Industry Information

Level Sensors

Level sensors, also known as level indicators, are measurement devices used to determine the level of materials such as liquids, powders, slurries and granular materials. All of these substances have flow, meaning that, within containers, they naturally flow to become level due to the effect of gravity.

Quick links to Level Sensors Information

Applications of Level Sensors

Level sensors are often used in these industries:

Pharmaceutical Products Production and Distribution
For measurement indication of medical ingredients.
To monitor and control the oil or refrigerant level in heating and cooling systems.
Food and Beverage
For monitoring of liquid and powder food items during handling, packaging, and processing.
Industrial Manufacturing
To control the levels of potentially hazardous chemicals required in various processing applications.
For monitoring of liquid levels in restaurants and office buildings.

While they are typically only used to measure materials that flow, level sensors may rarely be used for the measurement of levels for bulk solids. However, different applications require different types of level sensors and the various criteria that should be used to determine what type of level sensor will be best-suited for a certain application includes temperature, material phase, density, container size, and chemistry.

Level Sensor Design and Customization

Level sensors typically include a switching mechanism, a tube, and a couple of areas of connection. However, the design of the level switch varies widely based on the desired application and the different factors previously mentioned. As a result of those wide-ranging factors, level sensor designs can vary from the simple to the exceedingly complex. In addition, the level sensors can be triggered by many different conditions, including pressure, temperature, and buoyancy.

Some additional features that more complex level sensors may include are thermal sensors, ultrasonic waves, vibrating sensors, and optical sensors. All of these sensors can be modified to recognize specific substances or reveal when a certain viscosity, density, opacity, or thermal conductivity condition is reached. For construction, level sensor manufacturers typically utilize stainless steel, brass, and a couple different types of plastics. Stainless steel is an excellent material choice due to its hygienic properties and high corrosion resistance, whereas brass works exceptionally well for petroleum-based liquids. The two most common plastics used to fabricate level sensors are polypropylene and polysulfone. These two plastics offer advantages, such as their availability in different colors and the fact that they are good choices for acidic conditions (e.g., electroplating and metal cleaning) as well as lower-temperature food processing applications.
