Oil Level Sensor

[CO_Skymaster]

I've been investigating a product for Aircraft Extras allowing you to place a sensor in the bottom of the oil pan and alert the pilot when the oil level becomes low (around 4 quarts). If I started out with a normal amount on oil on a cross country trip and the sensor went off, I would be looking for a place to land right away. The sensor can be place in the drain holes. The problem I see is the lack of clearance between the nose wheel and drain plug in the front and dealing with oil drains in the rear. It is blocked by the muffler and pulling the sensor all the way out while trying to drain would be a mess. My question:

1. Is there another port on the oil pan for this purpose? (The sensor was designed for Lycoming and it looks like they have couple)

2. Is there any type of STC which allows you to place another port on the bottom of your oil pan?

Thanks for any advice,

Karl
