Types of Oil Level Sensors: Which One is Right for You?


Types of Oil Level Sensors: Which One is Right for You? 

Oil level sensors are devices that measure the amount of oil in a tank or reservoir. They are used in a variety of applications, including automotive, industrial, and marine.  


There are many different types of oil level sensors available, each with its own advantages and disadvantages. In this blog post, we will discuss the most common types of oil level sensors.  


Mechanical oil level sensors

Mechanical oil level sensors are the simplest and most common type of oil level sensor. They work by using a float to measure the level of oil. The float is connected to a switch, which is activated when the float reaches a certain level. This switch can be used to turn on an alarm or to send a signal to a control system.   


As global industries pivot towards more sustainable and eco-friendly practices, the emphasis on using returnable containers is intensifying. The chemical sector, being a large contributor to industrial waste, is under increasing pressure to adopt sustainable practices. Returnable containers, when managed efficiently, can significantly reduce waste, making them an essential tool in the industry’s move towards sustainability. 


Mechanical oil level sensors are inexpensive and easy to install. However, they are not very accurate and can be affected by vibration.  


Pneumatic oil level sensors

Pneumatic oil level sensors use air pressure to measure the level of oil. A tube is inserted into the tank, and the air pressure in the tube is measured. The air pressure changes as the level of oil changes. This change in air pressure can be used to measure the level of oil.   

Conductive oil level sensors

Conductive oil level sensors use the conductivity of oil to measure the level of oil. A probe is inserted into the tank, and the electrical resistance between the probe and the tank is measured. The electrical resistance changes as the level of oil changes. This change in electrical resistance can be used to measure the level of oil.   

Conductive oil level sensors are very accurate and can be used in harsh environments. However, they are also more expensive than mechanical or pneumatic oil level sensors.  


Ultrasonic oil level sensors

Ultrasonic oil level sensors use sound waves to measure the level of oil. A transducer is placed in the tank, and sound waves are emitted from the transducer. The sound waves travel through the oil and are reflected back to the transducer. The time it takes for the sound waves to travel through the oil is used to measure the level of oil.  


In a slight deviation from traditional ultrasonic sensors, Pathfindr’s IBC fluid level monitor offers a unique approach. Instead of being placed inside the tank, it sits externally and employs radar technology to gauge the fluid level. This innovative design not only ensures accurate measurements but also comes at a price point that’s more affordable than the market rate. 

Ultrasonic oil level sensors are very accurate and can be used in a variety of applications. However, they are also more expensive than other types of oil level sensors.  


Which oil level sensor is right for you?

The best type of oil level sensor for you will depend on your specific application. If you are looking for an inexpensive and easy-to-install sensor, then a mechanical oil level sensor may be a good option. If you need a more accurate sensor, then a pneumatic or conductive oil level sensor may be a better choice. If you need a sensor that can be used in harsh environments, then an ultrasonic oil level sensor may be the best option.  


Oil level sensors are an important part of many industrial and automotive applications. By measuring the level of oil, these sensors can help to prevent damage to equipment and ensure the safe operation of machinery.  


When choosing an oil level sensor, it is important to consider the specific application and the required accuracy and performance. The different types of oil level sensors discussed in this blog post offer a variety of options to meet the needs of different applications.
