This meter appears to be well made and I have had good luck from VEVOR in the past. I am using it on a diesel fuel transfer tank. This fuel meter works with diesel fuel, gasolines, kerosene, mineral spirits, stoddard solvents and heptane. It measures in gallons and tenths. It has one master meter that keeps up with total gallons and second meter that is resettable by turn the wheel on the side. The master meter can be reset and this unit can be recalibrated if it ever gets off.
