Believe it or not I put these on my flexicoil sprayer the 65xl and was able to calibrate my nozzles to the new meter and it was pretty accurate I bought a bag of 20 so I had back up but the original lasted 2 years now pretty durable wasn’t expecting that

Great replacement for the flow sensor on my Red China laser.

I was able to connect this sensor to Raypak Avia water heater and it is compatible. I use ABC adapters from Home Depot ex: "LESSO 2 In. ABS Female Adapter Hub x FIPT" or "LESSO ABS DWV 2" Union HxH" which makes it easy to detach if needed. So far I think it's a good product.

Works well was easy to setup. Using with an arduino uno that has an lcd display to measure total volume and rate of a variable rate spraying system. Read the description. Make sure that the sensor will work for the volume per minute you need measure.

Works good but fairly loud when spinning. I can hear the thing spooling up in the basement of my house from the main floor. It's been in service as part of my acreage water system for 9 months now and no issues other than the noise.
