Compact probe high precision ultrasonic liquid level sensor DS1603 V2.0

Short Description:

The DS1603 V2.0 ultrasonic liquid level measurement sensor series breakthrough the traditional opening can installation method and achieved the real-time non-contact liquid level monitoring in a closed container. The sensor shall be attached to the bottom center of the container to detect the liquid level height.
