DC5V LED Thermometer 3 Way Flow Meter FlowMeter for Water Cooling Liquid Cooler System & 2 Barbs

I bought this to add to my CO2 laser. Simple, attractive, and it works.

works fine

Works great. I use it on my CNC spindle and no leaks. Temperature gauge is accurate. Great addition.

Items came on time and well packaged… i chose the wrong size nozzle… was able to work around it as seen in the picture… would recommend the items… just make sure is for the correct hose your working with lol

Flow meter threads are not properly sized for replacement fittings. The acrylic case shattered when I screwed in a replacement barb. When I was testing, the flow meter would stop rotating as if it was caught on something, and I'd have to tap the device to get it spinning again.Have not yet tested the thermometer, but I bought this kit more for the flow meter than for the thermometer, so overall I'm disappointed with the kit.If you buy this with the desire to change the fittings, I'd suggest getting a properly sized tap and make sure the threads are appropriate before continuing. The acrylic is delicate!

Works great

If you're looking for a measurement of flow this is not the item for you. It only gives you a visual representation of if there is flow in a system, not how much. It is NOT a flow meter as it does not actually meter the flow of fluid through the system. It does however meter the temperature, if you're looking for something that both measures temperature and flow, I recommend either looking for a different alternative. If you're a diyer, I recommend picking up a small LCD display, an Arduino Uno, A hall effect flow sensor, and a small temperature sensor fitting. If you're willing to spend some more, it looks like Thermaltake offers a meter that monitors flow rate and temperature. As for if you picked this guy up, it works fine as a temperature sensor, you could always fit a hall effect flow meter in line with it if you require a proper reading of volumetric flow-rate.

Had to return first one. Appeared paddle was mounted off center. Second one is great. Thermometer seems to be very accurate.
