1 Inch PP Digital Turbine Flow Meter, 2.6-26 GPM Inline NPT Thread Flowmeter for Urea, Chemicals, Acid and Alkaline Liquids, Water, Diesel, Gasoline, Kerosene, and Other Liquids.

Just installed on a water line. Seems to work well, too early to make recommendation. The plastic 1" female threads are a little too large, so NPT pipes are very slightly loose and leak. Remedied with use of a lot of blue teflon tape. The 1" nipples grounded out to make a seal. White teflon tape was not sufficient. I am running at 70 psi, so at the upper end of its range. I calibrated it to work with water, which means changing the coefficient to 1080 (from 1000. I would think unquestionably water should be the preferred calibration, as this model is the one with poly fittings for potable water, unlike most of the other models which are aluminum and NOT recommended for potable water. I have not independently confirmed its calibration yet. My need does not require much accuracy.,

Works very well on surfactants. Heavy duty pump, should last for years

very good

I’ve only used this a little, but so far it works as it should. It’s easy to use, comes on automatically and goes off after some time. Installation was simple annd it’s easy to adjust the measured units- just follow the instructions. I’ll update this review if I have any issues.
