It arrived without frequency/flow graph or formula. I am using Arduino to measure the flow! So far, i do not know the exact flow to recommend it or not. I hope i can find such formula while searching the net
So far, so good! The product works as advertised and appears sturdy. I'm using this for an arduino-compatible project. My only know is that needed to use a decent amount of high-quality teflon tape to help with the seal.
Bought this to measure the flow rate from my 10GPM submersible pump which lets me calculate how many gallons I have in reserve in my 350' well. I first bought the 1" model, but it is different design and is very constricted. This one has negligible pressure drop even at high flow rates. I'm running it at 5V and making pulse decisions at 1V. The label indicates the pulse train frequency is 0.5 Hz * flow rate in liters/minute which matches what I get measuring the water quantity. The thread isn't an exact NPT, but threads and seals fine using Sch 40 PVC fittings and liquid thread dope with Teflon. I measure the pulse interval to 100uS resolution to get flow rate and count pulses to measure water quantity. The results look perfect using a $10 Cypress PSoC CY8CKIT-059. Try it - its great!
Works great, Thread is straight rather than tapered so I had to use some sealant when connecting to a PVC threaded connection.
