The device is mounted in the side of the oil pan, about midway.  When
about half of the oil is gone from the pan, a float touches a contact
that completes an electrical circuit and allows a light in the circuit
to illuminate.  Then you know that the oil level is dangerously low.
This warning device should not be substituted for a pre-flight oil
check, because you could be almost three quarts low and not know it.

The sensor shown at this page for Aircraft Spruce might work better,
because it activates much earlier, when the oil is maybe one quart low.

Subject: [FlyRotary] Low oil level

I have heard that the 13B has a low oil level device (that turned on a
light in the car?).    Can someone briefly explain how that works?
Float switch system, etc. The way my inititial intake pipes are routed I
won't be able to check oil so would like to use this or a similar
swiched device to know if oil level is down...
Thanks.  Doug / RV-9A FWF
