Installation Notes:
Once the adapter ends are installed on the upstream and downstream pipes, the meter is installed by tightening the collar nuts onto the inlet and outlet of the meter. These "true-union" fittings then allow the meter to be easily rotated to the proper orientation (face up), or removed for cleaning, repair, or replacement.
IMPORTANT!
These meter threads look practically identical to the NPT adapter threads BUT THEY ARE NOT!
Trying to install the meter without the adapter will damage the pipe's threads, the meter's threads, or BOTH!
The 1 1/2" size meter has what looks like a removable nut attached to the body. Do not remove this! The couplings that are sent with the meter will thread into this.

flow meter
Looks like a good fit for my needs, but the instructions were lacking. Instructions said mount horizontally, but did not say the meter should face up. I mounted it in a location that was high enough that I wanted to be able to look at it so I mounted it horizontally but facing toward me and not the sky. It did not read well at all. Show a picture or further explanation would be helpful.
RESPONSE FROM FLOWS.COM:
Thank you for your feedback! Instructions in the manual do state that it must be horizontal with the register facing up. In fact, when it is installed in any other fashion, it will not meet accuracy specifications. We have edited the product description so that others will see the installation requirement on the purchase page. We do have other meters that can have the register turned or you could also add a switch wire and a digital display that can be placed in an easier to read location. Please call if you would like to discuss. 855.871.6091 -

Inline Water Meter
Flows has been fantastic to order from. I had a faulty gallon calculator that got stuck on 9,999 gallons and wouldn't go any higher, so I got online to order another meter and decided to ask the Live Chat if I could fix it before ordering. They immediately shipped me a new 1 for free, no questions asked. This is my second water meter I've ordered through them and would definitely order with them again. Also, great service from the Live Chat, I believe her name was Michelle.

Plastic water meter
Work well. Wish they had a model without 4 readouts. But other than that very good.
