1 Check the DC power connections and DC polarity with the voltmeter.
2 Check fuse
No flow reading indicated
1 Check connection to the flow transducer.
2 Remove the transducer from the fuel line, and perform a no pressure flush with
the residual fuel left in transducer by covering the sensor inlet and outlet and
shaking for 20 to 30 seconds. Upon completion of the flush, finish with a low to
medium pressure (50 PSI Max) blow into the transducer from both directions
manually. When blowing through the transducer a whistling noise will indicate that
the turbine is rotating.
Low flow reading indicated
1 Check your primary and secondary filters for obstructions. If no filters are fitted this
will lead to blockage and damage of to the flow transducer (See Page 5).

2 Check that the calibration is correct.
No fuel reading
High or erratic reading
1 Check that the fuel connections are well made. Air in the fuel lines will cause erratic
or high readings.
