Not the product it was suppose to be. Accuracy is not very good.

Reliable and accurate enough for our needs. We needed adaptors to fit our piping needs and eventually that caused leaking problems for us - the plastic connection here cracked when we over-tightened it - my fault entirely. Very useful piece of kit for the $$s.

Good Flow meter. Installed and works great. If you are looking for a flow meter for water this will be perfect. It is labeled for DEF (diesel exhaust fluid) but if you read the small print it is the same calibration as water and will work fine. Very happy with the purchase and bought it here for about $50 less that I could find the exact meter anywhere else.

I purchased two of these high priced meters. Both of them show flow and record gallons any time fluid is present, even with the valves closed and absolutely no flow through them. Very displeased.

I have a tank system for my water use. This is in line on the water pump for my house. Quite accurate counter. Does not show flow rate just total gallons used with a total that can be cleared along with a running total. Will buy again when this one dies.Update on new one. The one I ran for 4 years started getting up to 10% inaccurate readings compared to our water deliveries. Tried changing batteries, no change. Bought new meter and finally when water was delivered lined up with a day I could install this. Found the old one was worn out, turbine was loose in the housing. Installed new one same as the last 3 I have installed. Noticed right away there was no decimal point, should not be a big deal. Water delivery was today, the new meter was 27% off. Not real precise and the furthest off I have seen any GPI product off before. Not real happy when the price was a lot more than the last one and now seems to be hard to find as well.

Works great. Use it to measure water in mixing a spray tank. Does the job well.

Had several of these over the years. Now that they have user replaceable batteries they took a good product and made it better.

DO NOT BUY FROM, ordered 2 items, only 1 showed up and it was broken. It has now been 3 weeks and there has been no response to refund me or send a replacement. DO NOT BUY FROM

I'm disapointed, it's not a flowmeter it's a flow totalizer, you never get your flow rate
