TQM Meter for Fuel Dispensers Component Technical Manual
3.5 Mechanical Adjustment
For the TQM meter to function correctly, the control valve must fill the front and rear
chambers in a specific sequence in relation to the pistons. This is dependent upon the
position of the control valve relative to the crank shafts.
The correct positioning of the control valve, gears and crank shafts are shown below:-
