Low Water Flow on A/C Discharge

[memiller279]

Since this is the closest thread to the problem I've had in the past I thought I would post here. I've had similar problems where a fish clogged the thru hull and the pump burned out due to lack of water. (It was really clogged.)

I wanted to know if there was someway I could wire a DC water coolant alarm into the system. This seems difficult as the Reverse Cycle is an AC system and I think (or at least I'm trying to) that the alarm should only be active when the pump is supposed to be running.

I already have an alarm on my main panel (DC side) but I'm not sure how the wiring would work.

Thanks

There are ways to do this. I have temp sensors connected to my exhaust elbow to sense an overheat situation with an alarm. It's based on a Chetco Systems engine gauge application. This app would allow a sensor for temp monitoring on the AC system or a normal water flow pressure sensor in the raw water line.

But for AC, this seems like an unusual occurrence and might not be worth the investment. I believe most would be protected by a high pressure sensor in the freon system and shutdown on their own if you noticed it in time.

Our AC, and most I have worked on, automatically shuts down if the water flow stops for any period. Chuck
