Review: Working good for 2 months.
Review: the way this unit is designed it blocks of a full 1/2 of the flow so it can direct the rest of the flow into the paddle wheel. Any time you run water through a reduced opening it causes substantial pressure drops at higher flows. The way these units should be designed is so they widen first so when the block off part of the area for the wheel it still leaves a full 1" diameter open. If they had done that it would not have caused such a large pressure drop. It may work ok if you place 3 of these parallel but that is a lot of 1" fittings to pay for.

*by M***H on 11 July 2025*

I bought this to monitor water flow on my home's water main. I connected it up to an ESP32 with ESPHome on Home Assistant and it worked well to count the pulses and report gal/min etc. So it works as advertised in terms of measuring water flow....however there a few problems. Firstly, the listing says it is BSPT (British Standard Pipe Tapered)... this is not true. This is actually BSPP (British Standard Pipe Parallel). This means it needs a BSPP adapter to NPT if you want to use this in the US. It also means that that the sealing is done with an o-ring. I purchased the adapters on Amazon but the o-ring seal that came with it was on the inside (like a garden hose).. The threads are not long enough on this device to seat against the o-ring.. so it leaked badly. I tried using PTFE wrap... it leaked... I tried thread sealer... it leaked. Everything I tied leaked at my mains pressure. Then the leak got bigger until BOOM! The threads blew off. Thank goodness I was still standing there to shut off the water. After a day of pondering my life choices up to that point, I decided to purchase the brass version sold by this company. This was also BSPP. I had also purchased dowty seals of the appropriate size (after tons of research on british plumbing standards)... I was able to get a good seal with the brass version with dowty seals and PTFE as a back up. I would say, don't buy this for anything more than a few PSI of water pressure... its way too risky given the catastrophic failure I witnessed. spend a few extra dollars (literally only a couple more bucks) and get the brass version for higher water pressures (like your home's water main).
