Level Sensor: What it is and How it Works

A level sensor is an essential device used to measure the level of liquids or solids in various applications. Read on to learn more about its functions, types, and benefits.

Level sensors are used in various industries, including pharmaceuticals, food and beverage, oil and gas, and wastewater treatment. They are designed to detect the level of liquids, solids, and slurries in tanks, vessels, and other containers. A level sensor measures the distance from the sensor to the surface of the material being measured and provides accurate data that helps operators monitor, control, and optimize their processes. In this article, we will discuss level sensors in detail, including their types, benefits, and applications.

Types of Level Sensors:

Contact Level Sensors:

Contact level sensors come in direct contact with the material being measured. They are designed to measure the level of liquids, powders, and granules in containers. Contact sensors include:

  • Float level sensors
  • Conductivity level sensors
  • Capacitance level sensors
  • Ultrasonic level sensors
  • Magnetic level sensors
  • Hydrostatic level sensors
Non-contact Level Sensors:

Non-contact level sensors do not touch the material being measured. They use various technologies such as light, radar, and sound waves to measure the level of liquids, powders, and granules in containers. Non-contact sensors include:

  • Optical level sensors
  • Infrared level sensors
  • Radar level sensors
  • Laser level sensors
  • Microwave level sensors
Benefits of Level Sensors:
  • Accurate measurement of liquid and solid levels
  • Improved safety by preventing overfilling and spills
  • Reduced downtime by preventing tank overflow or emptying
  • Increased efficiency by automating processes
  • Lower maintenance costs and longer equipment life
  • Enhanced productivity and profitability
Applications of Level Sensors:
  • Food and beverage processing
  • Oil and gas production and refining
  • Chemical manufacturing
  • Pharmaceuticals
  • Water and wastewater treatment
  • Agriculture
  • Mining
  • Energy production

Fuel Level Sensor Manufacturer

Filpro Fuel level sensoris a low cost capacitance type level sensor. It is designed for monitoring levels in fuel tanks of vehicles, Bulk storage tanks fitted on vehicles, diesel storage tanks.

The Design is simple & light weight. It measures the level accurately and reliably. The sensor output is connected to vehicle monitoring and tracking system or level indicators.

The sensor consists of measuring probe which is encircled with a reference probe. This given more linear output and is not affected by turbulence inside the tank.

Fuel Level Sensor As the fuel level increases, the capacitance value also increases. The fuel acts as the dielectric between electrodes. The increase in capacitance directly proportional to increase in fuel level. This change in capacitance is measured and converted into 4-20mA, 0-5V, 0-10V, RS485 O/P.
