New page

Many of us have found, and the factory confirmed when I spoke to them, that the standard float style sump level switch is prone to issues. It can sink at high angle of attack and power settings, particularly at altitude. Folks have come up with a couple of solutions.

== Gems Optical Sensor ==

It's a VP03E, just follow the link for purchasing information. This is a powered (12V) optical sensor that senses the presence of fluid that is reasonable impervious to fuels, and is a direct screw-in replacement for the factory system.

 After some  research, I found and ultrasonic sensor with is rated  for liquid and  includes gasoline. It is also NPT, so very easy to swap for  the  existing one. This is an epoxy device with a metal shield on it. Inside  it  has and ultrasound emitter and receiver. The presence of liquid (in  this case fuel)  creates a distortion in the ultrasound and that  triggers the sensor. The sensor  can be ordered as a NO (Normally open)  relay, which closes when liquid is present.  (MODEL LVU-A716)

-    I am glad to  report that I have experienced no more  flickering or false alarms. It  works great on the ground while taxing, turning,  at low RPM and high  RPM, flying even with nose up or nose down attitudes. It  stays green  all the time. I guess that in the case of low fuel in the wings and  in a  nose down it might let some air in the tank and that could trigger the   sensor, I will let you know if I see that, but it might take a while as  I  rarely fly with low fuel on the wings. I also checked with low fuel  on the sump  to confirm that it triggers the alarm when it supposed and  it certainly does. Differently  than the float sensor, the ultrasonic  sensor has no moving parts. It sends an  ultrasound. The ultrasound is  not affected by vibrations, or movement. If there  is fuel there, it  will signal it, if not it will not. Simple and works.<br/><br/>
