A few years ago the pump in a chiller failed and ever since I haven't trusted the alarms in the chiller (also a CW5000 like this one).

I put a computer water-cooling flow meter in the laser-out and cooler-in line. Now I can verify at a glance that coolant is flowing.

It's one of these:

I have another one that also fits a digital thermometer, but haven't gotten around to putting it in yet.

If you don't want to have to remember to constantly check visually, you can buy a sensor that interfaces directly with your Ruida controller. The controller will constantly monitor flow and pause the machine if water flow ceases. Less than $10. Alibabba has them for less. If you want to pay a little more to get it faster and live in the US, they sell them here:
