Important Note: Aluminum ttings should only be used when the ex lines are mounted on the inlet of the ow
transducer. Otherwise, steel, stainless steel (SS), or brass should be used.
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 ensure the pressure drop of the flow transducer is
appropriate for the maximum flow rate for your engine, refer to the transducer’s specifications 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.
C. Do not remove the yellow caps on the flow transducer until the fuel hoses are ready to be installed.
D. The flow of fuel through the transducer must follow the direction marked on the transducer.
E. The flow transducer must be mounted so the wires exiting the transducer are pointing up, or the cap with
five bolts is pointing up, or the output port is pointing up, or any combination thereof.
F. Before connecting any hoses, thoroughly clean them and ensure they are free of any loose material. High
air pressure may be used, however, do not allow high air pressure to pass through the flow transducer.
G. When mounting a Fuel Flow Transducer, make provisions for the Fuel Pressure Transducer as necessary.
H. If the flow transducer is hard mounted to a bracket, DO NOT connect the Black Ground Wire on the
flow transducer. The bracket will provide the necessary ground to the transducer.
I. You may want to consider using some fittings and hoses shown below.

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.
