The instrument used to monitor and maintain liquid and solid levels in containers, tanks, and silos is called a level sensor. The sensors turn the collected data into electronic signals after sensing the liquid levels. Point-level sensors and continuous-level sensors are the two types. The need for level sensors is expanding as it becomes more difficult to determine the exact level of fluids containing bubbles, such as milk, glue, ink, and soap. These are widely utilised in the food and beverage industry, medical, printing, and agriculture sectors due to their small size, low cost, and excellent precision. As a result, the level sensor market in North America is estimated to reach US$ 3.65 billion by 2027.
