650063-503 MP/fuel flow gauge

I appreciate your response. The part number I listed is the number listed in the POH in the equipment installed section. The only other information I can show is a photo of the indicator mounted in the instrument panel. I guess I can get the make of the indicator if I remove it from the panel. That's the last resort though.

P.S. Can't rotate image to the left.

It’s like a three turn spin… fully developed.  

Gravity on!

What was the question that went with the pic?

I’ve searched both the J parts manual and the Mooney website.  Both draw a blank for the part number.  You may have to remove it to see who made the gauge.  In all likelihood the transducer will be a Flow Scan, now part of JPI .

Roman,

We can probably ask Alan about that instrument… he may even have one sitting on the shelf already…

@Alan Fox is really good with pre-flown Mooney parts, including instruments…

Best regards,

It appears to have a small display window at the bottom of the gauge, does it power up?  If so it’s worth hooking up a transducer to see if you can get it working.  The trick after that it getting the correct K factor.

I have a few old transducers in the shop, I could send you one to try.

Alternately I have a used JPI FS450.

Could you post a picture of some of your xducers? I remember what mine looked like.

That's not a window in the instrument. It's a reflection off the glass.

Just search Flow Scan 201 transducer, this is what I came up with.  Also zoomed in on your gauge, sure looks like a small display window at the bottom.

You're right!!! There is a display window at the bottom of the gauge,  All these years I never noticed. Mainly because it was turned off. There is a blurb about it in the supplemental pages in Fuel Management System section of the POH. It has an on/off/ dimmer knob at the top right of the gauge. When you top off the tanks (65 gal for mooney) you enter 65 in the display with a little toggle switch at the bottom left of the gauge. As you fly it counts down so you know how much fuel you have left. But no clue as to manufacturer.
