3/4" Water Flow Sensor Food-Grade Switch Hall Effect Flowmeter Fluid Meter Counter 1-60L/min

Working good for 2 months.

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

This flow control was used on my Pool monitor system with very good results

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.

I haven't finished integration, but initial tests are very positive. I am running this meter on 3v and so far it's working great. I think there's a small paddlewheel inside that spins to count flow; I don't have measurements on precision yet, but the numbers I'm seeing show it to be quite sensitive indeed. I've connected it to a SEEED Xiao ESP32C3, and configured it with ESPHome as a pulse counter, and then integrate that pulse counter into a volume measurement. I still have some work to do on the calibration, but very pleased with this so far. I haven't compared it to others, and I think there are some improvements to be had in sturdiness (it's cheap plastic, but that's obvious from the photos), but overall I am excited to have a working meter.

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.
