What Is an Ultrasonic Level Switch?

To know what an ultrasonic level switch is, you will first need to learn about the features and uses of a level switch. Level switches are instruments used to detect the presence or absence of certain process materials. In addition, these measuring tools are also known for offering overfill protection to both people working with liquids and people working with solids.

If you have a point-level switch, you will need very little time for determining whether a liquid or solid has managed to reach the level you wanted it to reach. However, there's a small limitation of this instrument. You will not be benefited much by using it if you need to measure all intermediate levels; for instance, we would not advise you to use this device for continuous level measurement. This equipment is typically used for detecting the level of materials in pipelines, silos, storage tanks, and process tanks in process industries. You may be looking to find out a leak in a storage tank or pipeline or protect a tank or silo from being overfilled having a point-level switch is a must for you.

Let us now come to the actual subject of this write-up i.e. ultrasonic level switch. You will need this instrument for detecting the level of bulk slurries, liquids, and solids. The most fascinating attribute of this instrument is that it is non-contacting in nature. This means, unlike the invasive contact instruments used for determining levels, the ultrasonic level switches do not get any kind of buildup on their sensors.

Another notable feature of these ultrasonic units is their rugged design. They combine electronics and sensors in one robust device. The unit is absolutely devoid of any moving parts, which makes it almost maintenance-free. Its transducer is also special; it is inert to the majority of the chemicals these instruments usually come in contact with. In spite of having the ability to deliver quick results and requiring almost no maintenance, this measuring equipment delivers truly incredible performance.

This ultrasonic level measurement device is used for gauging levels of solids, slurries, and liquids in several industries; however, its use is most common in the chemical manufacturing industry. It is the preferred choice of the majority of the industries primarily due to its great flexibility. You can use this equipment both in areas with DC and AC power supplies. Operating the device also is pretty easy; it comes with easy-to-use 2-button programming. For liquids, the maximum range of the device is 5m and for solids, its maximum range is 3m, which automatically makes the product a unique level measurement tool.
