Is this a caustic soda plunger metering pump? What does each grid represent when adjusting the stroke? How is a large grid calculated then?

Thank you to all the brothers, sisters, uncles, and aunts
Adjusting the stroke means adjusting the flow rate; it allows the flow rate to be adjusted between 0% and 100%. When set to 20, it means that the flow rate at that point is equal to the maximum flow rate multiplied by 20%
It’s just a percentage of the total flow rate. It’s very simple, but not accurate at all! Haha. It can only be considered as a form of psychological comfort.
This is the stroke adjustment knob for the metering pump; the greater the scale on the knob, the longer the stroke of the plunger, and accordingly, the more volume of fluid the pump can deliver. To know how much quantity corresponds to each scale, one must first check the pump’s nameplate or specification sheet; these documents usually indicate the pump’s maximum flow rate. By dividing that flow rate by 100, the value obtained represents what each scale on the stroke adjustment knob corresponds to.
The rated flow rate of this pump is 1000 L/h, so what is the flow rate for each stage?

The quality of the Epson pumps is really not impressive at all. . It’s terrible; it’s only suitable for purchases made by organizations that use public funds. . .
Previously, each large section was considered to be 10%; P should be 20%, which has been corrected
