Seems to have a decent variance when it’s not a lot of fluid going through

The price was good and seemed to work as described but have not run calibration tests yet. I was able to find online programming and application information but it would have been nice to provide links to technical data sheets and programming examples.

First you need to know that the output is NPN (sinking). That means that it gives you negative pulses. Works well with a Click PLC using a high speed counter input. I can't vouch for the accuracy because I just needed to detect flow. It does detect pretty low flow. The threads sealed well to NPT to PEX brass fittings with plenty of thread tape. It's cheep and does the job.
