Review: Works as advertised. - Easy setup. Seems to be accurate. I use mine to display outdoor watering usage and to calibrate soaker hose coverage. As mentioned in another review, sediment can cause it to stick, but that's to be expected with this type of device. I did put a sediment filter ahead of it, and flow does not seem to be reduced. The filter has the added advantages of preventing clogs downstream. I installed the unit with adapters to quick connects so that if it sticks, I can just remove it and poke a pencil into the outlet and unjam it. I've had more expensive flowmeters and they all have disadvantages -- the plunger types can jam with sediment, and others have been a lot more difficult to correct than this one. The impeller types have their own issues of not being particularly reliable unless you spend several hundred dollars. The simplicity of this unit overcomes the one disadvantage Review: Simple and effective - Simple device that works like it should. I checked it by timing the time required to fill a 30-gallon container, and it is accurate within what I can measure using my iPhone as a timing device. ## Features - Price For: Each GPM Max.: - Flow Range (GPM): - O-Ring: - Flow Range @ LPM of Air: - Flow Range @ SCFH of Air: - Flow Range @ SCFM of Air: - Flow Range @ CCM of Water: - Flow Range @ GPH of Water: - Flow Range @ GPM of Water: - Master Totalizer: - Flow Range @ CCM of Air: - Pressure Drop - 100% Flow (PSI): - Gauge/Conductor: - Standards: - - Max.
