Description
Overview
GAOTek high accuracy ultrasonic level meter gauge uses the time required after the transmitted ultrasonic wave passes through the material level or liquid level to reflect to calculate the distance. Because it does not contact the medium, the installation and maintenance performance is more and more used in today’s industrial field. The measurement of the height of various liquids and solid materials, such as the measurement of the liquid level of tanks, pools, and reservoirs, has an irreplaceable advantage especially in certain places with high sanitary requirements.
