SV-EMS-220 Installation and Configuration
7-36 SkyView System Installation Guide - Revision K
This configuration can trap bubbles in the transducer, causing jumpy readings. The inlet port,
outlet port, and flow direction are marked on the top of the FT-60.
Rotax Placement Recommendations
If installing on a Rotax 912, review Figure 35 for recommendations specific to these engines.

Figure 35–Rotax Fuel Flow Sensors (Single-ended Measurement on Top and Differential Measurement on
Bottom)
In the differential fuel flow configuration in the lower portion of Figure 35, the first fuel flow
transducer measures the fuel flow from the fuel tank. The second fuel flow transducer
measures the unused fuel flow that returns to the fuel tank. The SV-EMS-220 takes data from
both transducers and calculates net instantaneous burn rate.
Fuel Level Sensor
Dynon Avionics does not sell fuel level sensors.
The SV-EMS-220 supports both resistive type sensors as well as capacitive sensors which output
a voltage (e.g., Princeton). If you have a capacitive sensor which does not output a voltage on
its own, you may be able to use Dynon’s Capacitance-to-Voltage Converter. Read the relevant
section below for the type that you are installing.
Fuel level sensors must be calibrated. Your SkyView display utilizes onscreen
wizards that help you do this. Go to the EMS Calibration Menu to access these
