When it comes to non-invasive point liquid level sensors, there are a variety of technologies to reflect on. It is imperative to weigh all the benefits and drawbacks of the different technologies. It may also be possible that a certain sensor may be advantageous for certain situations but may not be able to achieve the same accuracy and results in other situations.

There are two main types of liquid level sensors: point level and continuous sensors. Here, we have gathered information on both types of sensors and the uses and applications of each.

Point Level Sensors

Point level sensors are primarily used to detect the absence or presence of liquid in a vessel. They work via magnetic fields, similar to a switch with an on/off pattern, which allows them to sense the liquid levels within a container. For instance, it may raise an alarm if the liquid levels are higher than normal. Similarly, it could also be used to signal lower than normal liquid levels.

Point liquid level sensors have their advantages. They work well with viscous fluids, and the magnetic field is not disturbed by the resistance within a liquid. The drawback of these sensors is that they are unable to accurately tell the exact amount of water within a vessel or container. They alert only based on high and low levels of fluid.

This type of sensor is mainly used in water tanks, spill-prevention sensors, and pump protection alarms to signal the rise and fall of water levels within the tank. The sensor is usually connected to the water system and automatically shuts off the machine when the tank reaches a certain capacity.

Continuous Level Sensors

Unlike point level sensors that can only signal whether or not liquid levels have exceeded or receded from a certain mark, continuous level sensors are designed and calibrated to accurately measure the amount of liquid within a container or vessel. These sensors are crucial in situations where the accuracy and precision of water levels are vital.

Continuous level sensors have many benefits regarding the precise quantity of a given liquid. However, a major drawback is that, since these sensors are dependent on calibration, the width, height, and other capacity factors need to be taken into account. Other factors such as temperature and volatility of the liquid are also imperative to note before putting the sensor to use.
