4.3 Reset of quantity indication:

Press button START / STOP means quantity indication = 0.00.

4.6 Switch off display:

In case that the flow rate is not recorded within 90 seconds and no button is pressed, the display will
be switched off automatically (modus of saving energy). The indicated values are saved and will be
shown on display again after switch on of the FMT.

4.7. Directions of measuring accuracy:

The flow meter FMT is for recording the dispensed liquid quantity. By manufacturing it is precalibrated
for the dispensing of fuel oil and Diesel oil. The highest measuring accuracy will be reached at a
dispensing with a constant flow rate.

Different causes can influence the intended measuring accuracy.

1. Viscosity of dispensed liquid
2. Kind of dispensed liquid
3. High pulsation and flow rate of the dispensing pump
4. Mounting conditions

In case of an inaccurate measuring the FMT can be recalibrated (as described under point 4.8).

A recalibration is also necessary in case that the FMT has to be dismantled or if other liquids as fuel
oil and Diesel oil are dispensed.
