Cloudray Water Sensor HL 30 Chiller Review

My S&A 5200 cooler's flow sensor has failed and this replacement fits perfectly. This sensor seems to be a modification of the sensor I had in the radiator and it seems to be better made. The only problem is that the new sensor had a quick connector and it was hardwired into my cooler. It's no problem for me to cut the connector and solder the wires. Before purchasing, note that the wiring may not be connected to your cooler.
