Dual scale liquid level gauge

This level gauge has two columns of scales, one is the commonly used level height scale, and the other is the volume scale at the same height. It can display both height and volume. For tank car level gauges, they are generally installed in the middle of the tank car, with a flange of DN100 and a height that depends on the height of the tank car. There are two circles of markings on the meter head, one for the height of the liquid and the other for the volume of the liquid. For side mounted magnetic flip plates, the left scale represents the height of the liquid, while the right scale represents the volume of the liquid inside the tank. For specific instructions, please refer to the tank truck level gauge or magnetic flap level gauge.
