How can the liquid level height in industrial tanks be transmitted wirelessly over long distances?
In modern industrial management, centralized monitoring of widely dispersed tank levels is a critical requirement. Traditional manual inspections or wired transmission methods are not only inefficient but also face significant challenges—such as difficult wiring and high costs—in complex operating environments. Millimeter-wave radar level transmitters, based on 79–81 GHz frequency-modulated continuous-wave technology and incorporating advanced wireless communication capabilities, offer an ideal solution to this need.
