Flowmeter Water Timer

This flow meter does exactly what I expect; it counts down to zero when the water flows, then shuts off the supply. It does not time the water, like the other kind of 'egg-timer' type of meters that are set for 'minutes' instead of gallons... It uses a small water driven wheel to turn down the dial, and needs enough flow to actually work. If you need to water small quantities, or don't let it flow fast enough, it won't work; get a flow timer instead. I use it to add water to the pool; put the hose in the pool, set the flow meter to 200 gallons and let it run. After the 200 gallons, it shuts off, so I can walk away and don't have to remember the hose is still on. I always leave it attached to the spigot outside, set at about 100 gallons. If I forget to turn the spigot off, the flow meter would limit the amount of flooding in case the hose bursts. This is my third flow meter in 10 years; you could say they last about four years, which is decent for the price.

Tested this yesterday and it worked as expected. Bought this as a safety device for my boat. Placed in-line with marina water supply. A pipe brake could overwhelm the bilge pumps. This meter shuts down after reaching a preset limit.

Some complain that the timer doesn't count down. I haven't had this problem, but I have higher water pressure, so that may be what's needed to have it work properly. Once the timer shuts off, the connection to the hose bib is at that pressure. This connection is weak and eventually breaks, causing a full pressure, open-hose release until you catch it and shut off the hose bib. I try to remember to turn off the hose bib before retiring for the evening but last night I didn't and woke up to a flooded back yard after this broke and ran over night. I suggest that if you use these, be VERY DILIGENT to not leave them unattended, because they WILL break.

I wanted it to measure ~ 100 gallons ... it's made to measure 1000 to 1500 gallons ...the smallest setting is 200 gallons and it is way way at the end of the dial.

I've been using these timers for about 20 years. I love that you can choose either minutes/hours or gallons (hundreds). I know my water rate goes up after 10,000 gallon, so this helps me keep track of usage in my gardens. My ONLY complaint is that the paper "guide" doesn't seem to last as long now as it used to. These latest ones I bought are starting to come off after just 3 months!! My last timers lasted 15+ years!

I have 2 of these devices now. They work great for my needs. I'm filling tanks vs watering. Water pressure varys. Measuring volume I'm able to reliably refill my tanks without being there easily. With a time based device I sometimes can only partially fill them and sometimes overflow.

The product I received has the same product number, but it is NOT the same as the one pictured (which is what I had before and which did leak a little bit around the screw, but it was easily sealed with Teflon tape) What I received is black, cylindrical length wise (as opposed to the pictured one which is more like a stack of pancakes), has the same timing/amount of water in gallons (important to us, as we need longer watering times), and best of all, no screws to leak from in the new design!!! As far as I know, this is the only product of its kind that has this long watering time (actually a much more precise measuring by gallons), and does not require batteries to be replaced, i.e it is purely mechanical. Remains to see how long this new design will last, the previous design lasted about three or four years each, probably due to extreme hard water in our area.

I have used these water timers for my vegetable garden for years. The are made from quality materials and they help me save on water bills with measured timer watering.

Good stuff. Works as promised. Maybe not designed for below 0oC. Measurement is very accurate and shuts off Everytime. Bravo
