DIGITEN G1-1/2" 1.5" Water Flow Hall Sensor Switch Meter 5-150L/min

Works perfect and easyto install.

What is the specification for the connector on this model?

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.
