SUL814 Ultrasonic External Mounted Tank Level Sensor

SUL814 external mounted liquid level gauges breaks through the traditional installation method of open tank contact, and can achieve true non-contact measurement of the liquid level in closed containers

SUL814 external mounted liquid level gauges breaks through the traditional installation method of open tank contact, and can achieve true non-contact measurement of the liquid level in closed containers. The sonar sensor (probe) is installed just below the outer wall (bottom) of the container to be tested. It does not need to open holes in the container to be tested. 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 airtight containers. The liquid level gauge has no special requirements for the material of the liquid medium and the container, and adopts the explosion-proof design to meet the explosion-proof requirements and can be widely used.
