Key Features

A liquid level sensor operates by detecting the presence or absence of material or determining the level of material
within a container. This is achieved using various technologies like capacitance, ultrasonic waves, or, as in the case of
radar, by measuring the time taken for a signal to bounce back from the material surface. Level sensing can be contact
or non-contact-based, depending on the method employed. A radar level sensor is a device used to measure the level of
liquids, solids, or slurries in various challenging industrial applications. It utilizes radar technology to determine the
distance from the sensor to the surface of the material being measured.
