The structure is similar with the glass panel liquid meter while it has frost against fin that can remove the influence by frost. We can see the change of the liquid clearly by seeing the fin change. It is widely used in chemical, petrol and other industries. The product implements HG/T21550-93 standard.

4.4 Installment and Use
4.4.1
The level meter should be vertically installed on the worksite, which is convenient for the operator to operate.
4.4.2
To make sure there is no clearance between the auto interlock of stop value and the back seat, turn on the valve handle when start it.
