Yeah, that would be fairly simple. Tell me, where do you want this to be triggered? I'm a bit confused about what you're trying to sense. Do you want to know when the pump is full on? Full off? Partially on?

To be honest, current sensing isn't all it's cracked up to be. One of the most useful things to detect would actually be when you have the pump turned on but it isn't working. The thing is, that means you have to sense when voltage is applied but no current is flowing. That's easy enough. But most motors don't fail open, they short out, so current WOULD flow, and your breaker or fuse would blow, and there's your indication.

So the fuse might be the BEST option.
