3.3 Tatsuno Meter Calibration
The Tatsuno Meter is used with petrol and diesel.
Calibration adjustments affect the volume of fuel delivered per revolution of the flow
meter, while the displayed volume always advances by exactly the same amount for
each revolution.
Calibration is achieved by using the Adjustment Wheel to alter the volume delivered
by the Flow Meter per revolution so that it matches the volume displayed after a test
delivery.
Refer to local legislation for requirements pertaining to calibration procedures.
Remove the locking pin prior to moving the Adjustment Wheel.
Figure 39. Adjustment Wheel
A single pitch-turn (one hole to the next) varies the flow by 0.04% (approx 0.2ml per
revolution). The meter can be adjusted up to a maximum of 0.64% (3.2ml per revolution).
After calibration, the meter must be wired with a sealed plate (Control Mark).

wheel in a clockwise direction.
Under-Delivering
When a Flow Meter delivers
