Description
Overview
GAOTek external ultrasonic liquid level meter is a device used to measure the level of liquid in a container or tank using ultrasonic technology. This type of level meter is designed to be mounted externally on the wall of the container, without the need for direct contact with the liquid. It operates by emitting ultrasonic pulses that travel through the air and reflect off the surface of the liquid, allowing the device to calculate the distance to the liquid and determine its level.
