2-20GPM Water Tube Design Liquid Flowmeter Measure 1"PT Dia Input

Bought this to rough in a flow switch before it is installed in a system. It was more accurate than I anticipated and I didn't have to make adjustments after installation.

The weight that slides up and down the rod to indicate the flow rate got stuck. No amount of tapping unstuck it. That is a basic design flaw. I had to get a replacement.

Good quality, clear view. Has to mounted vertically to read accurately.

Leaks quite badly around the threaded 1-inch pipe connections, even when wrapped liberally with heavy duty PTFE thread tape. I like that both gallons and liters are represented in large printing, but it would also be helpful to have them on both sides in case the orientation is off.

Good product but hard to take apart to clean if float gets stuck.

Simple, straightforward reading, used to verify flow against a digital flow indicator.

this unit was easy to install and works great

Leaks no matter what I do... ordered 5 all leak from threads. No amount of teflon tape or pipe dope helps
