Bill,
I have a "spare" 201B. If it was idle for a few years, could there be
deposits in the transducer that affect the flow? Perhaps clean
it with an injector cleaner or MEK.....
How strange were the results? Is it possible there is crud in the
fuel line. These transducers are very sensitive to turbulent flow.
Scott
PS Contact me direct if you wish to try mine.
PPS I have used two different 201B sensors with no need for "K" factor
adjustment.

Plane grounded for several years....new windshield, lots of dust and
debris , pulled DPU and fuel pressure sensor because of fuel pressure
problems. Unit was checked out and reinstalled. Got MP and RPM
stable. Strange results with fuel flow. Can't seem to get 43 gph
WOT. Engine feels strong. Might be transducer??? Rechecking wiring
today. Any thoughts ???
Bill,
Did you change anything just before the flow indication went
wonky? Moved the sensor, changed its hookup, etc.?

Does
anyone have a VM 1000 fuel flow transducer that they arnt using
at the
present time?
Mine is giving me strange readings and after running
the Transducer
Test, I dont know where else to look..
I had the
DPU checked out and upgraded. The fuel pressure was out
of
tolerance but the offset was constant,
so its usable at least for
the present.
If I had my druthers, I would like to borrow a
transducer, if
possible, just to check against mine. I understand
that
the original unit is a flowscan 201B and the VNS # is
3010032 or maybe 3010035.
Any help would be
appreciated.
