What Are Electronic Rotameters and How Do They Work? Electronic rotameters, also known as digital or electronic variable area flow meters, are precision instruments used for measuring the flow rate of liquids and gases. Unlike traditional mechanical rotameters, which rely on a float moving in a tapered tube, electronic rotameters use advanced technology to provide more accurate and reliable measurements with enhanced functionalities such as remote monitoring, data logging, and easy integration with automated systems. In industrial and laboratory applications where precision and control are paramount, these devices have gained significant popularity. https://www.ourmechanicalworld.com/archives/4109
