1.2 FLYBOX TFTHP FUEL FLOW
TRANSDUCER INSTALLATION

If with the fuel computer FC1 it's used the Flybox TFTHP
fuel flow sensor, read completely this section, otherwise
refer to the installation and use instructions of the sensor
used.

The TFTHP flowmeter is developed to measure low range
(3.6~120 l/hour) of fuel flow with high resolution output. It
has high chemical resistance to aggressive liquids and
hydrocarbons. The case can be opened for periodic
monitoring and eventual replacement of the tube.

RECOMMENDATION OF INSTALLATION AND USE:

- Check flow direction (arrow on sensor).

- Never clean the sensor with compressed air.

- Install a filter in the fuel line before the sensor.

- To mount the rubber tubes, use a drop of oil.

- The tubes before and after the sensor should be straight
for at least 5 cm.

- Connection of fuel flow are suitable for 6 mm tubes.
