One Structure and working principle
Flanges are added to meter with up and low valves. The flanges connect with tank and make a communicator with tank. Then the liquid level will be read from the Transparent glass tube or glass plate directly.

The upper and lower valves have steel ball inside. So if the glass plate or glass tube was broken by accident, the steel ball will block the channel under pressure, and to assure the container be sealed automatically which can prevent the liquid flowing out.

There is screw fixed on the valve ends. When sampling or repairing the meter, rotate the screw and dismounting the meter.
