Search the FAQ for entries containing:

Turbine meters can not tell the difference between air and liquid. It just knows the turbine is spinning, so any reading will be inaccurate if air is going through the turbine. Another reason to not put air through a turbine is potential damage. The air will make it spin extra fast, with no liquid for lubrication damage can occur. Then when the liquid get there it can hit the turbine like a hammer. It is recommended to slowly bleed to air out of the lines then reset the meter total.
