How to disable drip alarm on dosing pump???

[rdmpe]

I have a Welcon RateSaver 3 Enteral Feeding Pump that I want to use for dosing/topoff. I would like to disable the drip sensor on this thing. But I can't figure out how to do it. Anyone know how to do it? Here are some pictures:


Here is the overall picture, sensor part in the upper right.

Here is a closeup of the main circuit board

Anyone know how to mod this thing? I've seen a post about doing this mod to the kangaroo line of pumps, but those don't look anything like this one on the inside...

Thanks!

What happens is you just unplug the sensor board?

Haven't tried it, but I suspect that a complete lack of signal will spell trouble. The thing is looking for a signal that is broken by a drop of water every so often.

I found some modification instructions for the kangaroo line of pumps, and the mod is a connection between two pins of a large IC chip. So I imagine that the mod for this pump will be something similar. Wouldn't hurt to try though I suppose!
