An Introduction to Liquid Level Sensors and Their Variations

Level indicators are specific tools that various industries utilize to detect the level of liquids, granular materials, and powders. These devices are capable of measuring liquid levels inside a container. They can also detect and measure liquid in its natural states such as the sea or lake. The technology present in liquid level sensors has become more advanced, easy to use, and highly portable. Measuring liquids using these sensors only requires positioning the unit on the wall of the container with the liquid inside. In a few seconds after doing this, you will receive signals providing you with the exact liquid measurements.

These days, you have a wide array of ultrasonic level transmitter devices to choose from, which come with different technologies. Each offers its pros and cons. Here are some of the most common variations of liquid level sensors you will be coming across.

Capacitance liquid level sensors are popular for their ability to measure a good range of fluids like organic liquids and aqueous solutions and even some solids. The technology used in these sensors is referred to as RF for its radiofrequency application. There are no moving parts in this device, and it is very portable. You can bring it from one location to the next. The new technology present in capacitance liquid level sensors will not require any type of wire anymore to be extended inside the container.

Optical industrial sensor suppliers are well-known for detecting the level of liquids in liquid-to-liquid interfaces, sediments, and suspended solids. These sensors use infrared light technology, which comes from the infrared diode that helps detect the level of liquid inside a container. These sensors are ideal for level sensing aqueous liquids and corrosive organic liquids. Unfortunately, these units can be quite expensive with its laser feature. If you are on a budget, you might skip investing in this level indicator first.

Conductive liquid level sensors are presently one of the most common liquid level sensors used in the industry. Not only are they reliable but also, they are very portable and don’t have any movable parts. They are typically used for point level detection purposes and can measure different types of liquids on top of water, namely, caustic soda, nitric acid, hydrochloric acid, and ferric chloride. You only need low voltage power to use this liquid level sensor. They are very efficient industrial sensors for pumps and wastewater wells.

In terms of advancements in level reading technology, ultrasonic liquid level sensors are presently considered as the most advanced. They offer the most accurate and quick results. They are commonly used to detect highly viscous liquids and bulk solids. They are also ideal for detecting liquid levels in pump controls and for open-channel flow measurements and water treatment applications.
