We are working on our 914 fuel system. It has 2 Floscan 201B transducers
for flow gauge.

I called Flowscan about installation, and was told if using mogas, you
need to drain lines so there is no fuel in the transducer, or else the
optics will get varnished over. He said 70 to 80% of the time you can take
out the transducer and put a pipe plug in 1 end and use carb and choke
cleaner and let it sit. But if that does not work the transducer is not
serviceable.

Have those out there using mogas and 201Bs been draining lines during
times of inactivity?

How many have needed to clean or replace 201Bs?

Thx.

Seems it would be a lot easier to switch over to an approved fuel that does
no harm to the transducer just before shutting down the system if that is
possible. Adding a small tank of approved fuel with a fuel selector would
do it.

On my plane I have only one transducer that is located down stream after the
tank selector switch. I run mogas in one tank and 100LL in the other. I
always take off and land on the 100LL tank.
