Different Types of Level Sensors

Level sensing technology has been around for quite a while now and has been massively used in many industries. The latest advancements in the field also heavily affect the current equipment that operators depend on. The presence of liquid and solid level sensors has also been one of the latest industry trends, and many modern companies rely heavily on the machine. For this reason, it is vital to know more about the technology, including the different types along with their features and functions. Thus, this article will give you the information about the topic as it aims to explain more about each variety of level sensors.

This machine works by producing ultrasonic waves at certain ranges, aiming to measure the levels of sticky liquid and its bulkiness. The waves produced are then echoed back to the transducer, and this process is when the sensor can tell you the exact measurement of the materials. Although it may sound easy to operate, note that this type of machine is highly sensitive to certain variables, such as turbulence, pressure, moisture, and temperature. Thus, taking care of these variables before operating the machine is advisable to avoid inaccurate measurements.

One plus point of this technology is that it comes with a compact design, making it quite easy to handle and operate. However, this technology is also known to have invasive feature, meaning that it needs to touch the materials to work well.


When you find yourself handling materials that produce sediments, using an optical level sensor is the best option for you. The equipment is also highly adaptive to extreme pressure and temperatures. More importantly, optical technology makes it possible to detect tiny amounts of liquids.

Instead of handling the material with ultrasonic sensors, the capacitance will be a better option. The technology works by measuring the changes in the liquid level, which are then turned into analog signals. The signals are the key aspect that will come up with an exact measurement.

One benefit of this sensor is that it has no moving parts, which means easy maintenance as the parts are easy to clean. In addition to it, this type of detector also comes in compact designs, is accurate, and non-invasive. However, note that this type of machine can only work in certain materials so that those handling broader types of materials cannot depend on this equipment.
