I purchased the 3/4 and 1" models. I was thinking of using the 1" to push more water through. However looking at it from the end, it chokes down to 3/4" so both are the same size internally.

Worked great for 11.5 months with a RPI. Unfortunately it failed at 11.5 months with minimal use. When starting the flow it rattles around until the paddle wheel gets stuck. I need very low flow rates so it still flows water for me, but I wouldn't buy again.I'll have to drain the system to eliminate this part at some point.

Good product with good accuracy. Pressure drop across the meter was minimal.

Flow meter o in italiano sensore di flusso con connessione 1 pollice (G1) maschio / maschio.L'ho utilizzato per automatizzare l'avvio di un autoclave per riempire un serbatoio d'acqua.Il sensore manda in output un onda quadra con frequenza pari al numero di giri effettuati dal sensore, è possibile ricavare da questo paramentro il numero di litri per minuto / ora.Purtroppo oltre alle info stampate sul sensore, a casa non alcun manuale o foglio di istruzioni, ho quindi dovuto cercare in rete le specifiche tecniche del sensore:nel dettaglio:Rapporto frequenza l/min è di 4.8 come anche indicato anche nella descrizione,Output pulse high level Signal voltage >4.5 V( input DC 5 V)Output pulse low level Signal voltage Precision 3% (Flow rate from 1L/min to 10L/min)Output signal duty cycle 40%～60%Esistono due modelli versione1 e versione2 che differiscono solo dalla leggera differenza nel rapporto Litri/minuto, personalmente non sono stato in grado di capire con certezza quale delle due versioni è quella che mi è arrivata ma avendo trovato nelle specifiche tecniche stampate il rapporto 4.8 posso intuire che si tratti della versione1 (la versione2 dovrebbe avere un rapporto l/min di 4.7). Ottimo prodotto, spero che duri nel tempo.

Excellent for the price, but it it has its limitations. As other reviewers wrote, it restricts the flow. I wouldn't want to use it if a water line larger than 1/2 inch is needed. Calibration appears to be within about 5% from 0.5 gpm to 4 gpm. Below 0.5 gpm calibration falls off quickly. I showed an 18% error at 0.38 gpm. I didn't test it above 4.28 gpm which is all I got through my 1/2" hose.

Watch out since the internal bore is smaller that what you would expect. If you want a 1" order the next bigger size to avoid obstruction.

It works well for my application.I set up a solar water heater for my pool controlled by a Raspberry Pi. I am using it to provide relative flow rates while making minor adjustments to the actuator/valve, so I can provide a variable flow that is always a constatnt temperature higher than my pool temp.Not sure how accurate it is, but I do know that the value of 450 pulses/liter for the 1" as stated in the ad is not correct . If F=4.8 * L/M, then pulses/liter should be 4.8*60 or 288 which is the value that I am using, but I still suspect it is too high. Will have to write some code to allow me to calibrate it.Had it in my system for about a month now, no complaintsUpdate 6/4/2018.After adding 2 more solar panels, I am getting a max flow rate of 45 liters/min. Still running fine. but does deveop a louder hum at the higher flow rates. In addition at this increased flow rate I believe that it may have become a bottleneck considering the pump size that I am using to pump the water up around 25 feet to the solar panel.

I bought this sensor as an Arduino input to control my home's water pump. So far so good.
