2.12 Install the Fuel Flow Transducer:
The MVP can interface to many different types of flow transducers or the FT-180 Fuel Flow Transducer may be
considered for installation. The FT-180 should be mounted in the appropriate fuel line. Refer to the installation
notes listed below.

A. Only the Electronics International FT-180 fuel flow transducer (or an equivalent unit) should be
considered for use on a turboprop or jet engine. To insure the pressure drop of the flow trans-
ducer is appropriate for the maximum flow rate for your engine, refer to the transducer’s specifi-
cations and FAA document AC 23-16.

B. The Flow Transducer should be mounted so the fuel line exiting the transducer’s output port
travels up, even or drops no more than 4" per foot. If this is not possible, a loop should be put in
the fuel line exiting the Fuel Flow Transducer.

NOTE: The Stratoflex teflon hose can be much more flexible
and easier to route than most existing hoses. If you have a hard-
to-fit installation, you might want to consider this hose.
