SV-EMS-220/221 Installation and Configuration
SkyView System Installation Guide – Revision S 7-47
FloScan 201B sensor only: make note of the numbers on the tag (pulses / gallon)
attached to the fuel flow sensor.
Dynon Avionics supplies the
Electronics International FT-60
(Dynon P/N 100403-003) fuel flow
transducer. Dynon no longer
supplies the FloScan 201B, but
SkyView is compatible with this
sensor.
The SV-EMS-220/221 supports
differential fuel flow sensor
installations in Rotax 912 and 914
installations as illustrated in Figure
41.
Table 41 revisits which SV-EMS-
220/221 pins are compatible with
fuel flow sources.
General Placement Recommendations

Do not install the Fuel Flow Transducer, hoses and fittings near exhaust system or
turbocharger. Excessive heat can damage fuel system components.

Do not install 90 degree fittings (elbows) on the input or output of the Fuel Flow
Transducer. Doing so will cause turbulence in the fuel flow which causes inaccurate fuel
flow data.

Install the Fuel Flow Transducer with the three wires pointed UP.

Install a fuel filter UPSTREAM of the fuel flow sensor to screen out debris.

For best measuring performance, the fuel should travel uphill by one to two inches (25-50
mm) after leaving the fuel flow sender.

Placement of the fuel flow sender relative to other items in the fuel system like fuel pumps
is left to the builder. It is common to place the sender downstream of any auxiliary electric
boost pumps but upstream of the engine driven fuel pump.
Due to vibration issues, never connect the sensor directly to the engine.
