Description
Overview
GAOTek compact ultrasonic density sensor with NB-IoT connectivity is one type of liquid density sensors which calculate the density from ultrasonic wave speed in the liquid. As it is based on the principle of speed related to the density of media. So, it is applicable for liquid which is with known value of referenced density. It has a compact design with small dimensions, and it is easy to install. It is not necessary to be vertical in the liquid. Only if it is in the liquid, it is enough. Furthermore, it is applicable for customized design, such as different mechanical structure, measurement range, and other OEM/ODM business.
