Addressing the challenge of liquid level measurement

In industrial settings, accurate measurement of liquid levels is crucial to prevent potential hazards like spills, equipment damage, and accidents, which can negatively impact both businesses and the environment. Traditional methods often fall short, especially when dealing with tanks and containers situated in hard-to-reach, demanding constant surveillance and significant resources for maintenance.

Non-contact level monitoring emerges as a vital solution, offering precise measurements without the need for constant physical oversight. This innovative approach not only enhances safety but also streamlines operations by reducing the load on maintenance teams and mitigating the risk of overfilling or underfilling.

Prylada solution for non-contact liquid level detection

The Prylada IoT Gateway seamlessly integrates with a radar sensor to provide real-time data on container fill levels. Using mobile network connectivity, this information is further transmitted to a remote control system. Whether hosted on the Prylada Cloud, a private cloud, or your local server, our solution empowers you to store, analyze, and visualize collected data with ease.

How liquid level sensor works

Liquid level sensor

A radar level sensor is a type of non-contact sensors that uses pulsed coherent radar (PCR) technology to measure the distance to the surface of various objects. For example, the distance from a liquid level to the top of a container or vessel.

Operating principle

The sensor emits a microwave signal, measuring the signal's reflection time to calculate the distance to the liquid surface. This information is then used to determine the liquid level.

How liquid level sensor works
Difference from ultrasonic sensors

While similar to ultrasonic sensors, radar-based sensors perform better when there is foam, dust, or other particulates in the air. They are less affected by environmental conditions like temperature and humidity. Radar's reliability and repeatability are influenced by the fluid's dielectric constant. However, radar can compensate for fixed structures within the container and would skip this part. Additionally, radar-based sensors' working distance is normally bigger compared to one ultrasonic.
