Mechanical surge protection tank capacity indicator device for storage tanks.

Abstract

This invention falls within the field of industrial tank monitoring technology and lightning protection, relating to a mechanical lightning protection tank capacity indicator device. The device consists of a rotating shaft, a balancing unit, and a float assembly located inside the tank. The float assembly is connected to the rotating shaft via a connecting wire, and a pulling force is applied to the shaft. The height of the float assembly moves up and down according to the changing internal tank capacity. The connecting wire pulls the rotating shaft, and the balancing unit, connected to the rotating shaft, helps to stabilize and balance the force applied to the shaft. The rotating shaft has a mechanical display plate, which converts the rotation angle of the shaft into information displaying the tank capacity.The mechanical capacity indicator device of this invention does not require an external power source, ensuring that operators can still monitor the tank capacity even during power outages to perform emergency operations. Through an explosion-proof signal converter, information on the liquid level in the tank can be transmitted remotely, facilitating remote monitoring and preventing the risk of the piston hitting the top or bottom.
