The BL-YW-DS1603AQ ultrasonic liquid level analog sensor breaks through the traditional installation mode of open tank contact and realizes the measurement of liquid height in closed containers. The sensor is usually installed at the right bottom (bottom) of the measured container to detect the liquid level height. It does not need to open a hole for the measured container. It is easy to install and can be installed online. It can accurately measure the liquid level of various toxic substances, strong acids, strong alkalis and various pure liquids in high-temperature and high-pressure closed containers. The liquid level sensor has no special requirements for the material of liquid medium and container, and can be widely used.
