Answer: 
You could but would take some record keeping on your part. If you were trying to capture daily or weekly use, just start the timer off at say 800 gallons and at the end of the day or week, see where the dial ended up and just subtract it from 800 and the difference is gallons used. Over a whole growing sesson, I suppose you could just record the number of gallons you start out with and then as it winds Read More

Over a whole growing sesson, I suppose you could just record the number of gallons you start out with and then as it winds down with use, it will eventually shut off. Reset it and record that starting point and so on. Not real efficient, but doable. Hope it helps. Blessings. Read Less

Answer: 
There is no "memory" function. It is entirely mechanical. You must turn it on every time. It turns off after the approximate amount of water has been delivered.

Answer: 
Although I have never tried to use it in a gravity feed system, I do know that using it with a restricted water flow (water faucet opened only a quarter) the flowmaster will not always shut off. Hope this helps. Blessings

Answer: 
The answer is "depends". It requires FLOW to operate the APPROXIMATE flowmeter. Almost every water system is "gravity flow'. If you see a water tower or reservoir above the level of your home, it is gravity flow. Most home systems work on on 40-65 (average 50) pounds per square inch (psi). 40 psi is measured at the bottom of a column of water that is 104 feet tall. If you have a gravity feed of this Read More

Answer: 
Hello Mike and thank you for your question.
The Melnor 4.75 in. Flowmeter Water Timer will need a minimum of 8 pounds of pressure in your gravity feed system for proper operation. For example, the pressure from a “full” water barrel may be fine, but may not be sufficient when the barrel is close to empty. Operating Instructions can be found here: Read More

Remember that this device meters water in total gallons. To determine how many gallons to set your flowmaster for your plants, initially set the flowmaster to 800 gallons, set your sprinkler up to water your plants, turn on the faucet. Once you are happy with the amount of water that has irrigated your plants, turn off the water and see what the flowmaster dial stays. If it is at say 600, then it took Read More

Once you are happy with the amount of water that has irrigated your plants, turn off the water and see what the flowmaster dial stays. If it is at say 600, then it took 200 gallons to correctly water your plants! All you have to do next time is set it at 200, turn on the water and forget about it! It wll shut off automatically.

Answer: 
You need to research the water requirements for the plants you are watering, It also depends on the time of year. If it is a fruit tree, it requires little water (1-2 gallon a day) in the winter but can require up to 60 gallons a day depending on the size and kind. A basic rule is 1-2 gallons per square yard of "canopy" (area under leaves or foliage) every 2-3 days.

Rated 3.7 out of 5 by 13 reviewers.
Rated 5.0 out of 5.0 by It did the job well I needed a timer to control a sprinkler from a somewhat restricted-access water spigot. Although this unit is made of plastic (including the threaded hose connectors) it is fairly heavy duty and appears to be sturdy. The control dial is ratcheted so you can't rotate it backwards, which is fine but it could benefit from a molded-in arrow reminding the user to only rotate it one way. Overall, it serves my purpose well. October 11, 2016
Rated 2.0 out of 5.0 by not as good as I thought Placed on water spout and attached to hose...water leaked all over September 27, 2016
Rated 5.0 out of 5.0 by Exactly what I wanted This flowmeter works by volume, not time. Just turn the dial and it starts flowing, then will shut off after the volume is reached, no buttons, no batteries. July 23, 2016
Rated 2.0 out of 5.0 by May work, but not at low flow rate This device attempts to measure the flow of water and shut off after a configured amount has been delivered. Unfortunately, it seems to need a rate of several gallons per minute, which doesn't satisfy my requirements. The package itself does not indicate this, other than "not recommended for low pressure drip systems." May 27, 2016
Rated 4.0 out of 5.0 by Eval of product Difficult to read timer/flow gauge as my outside spiquets are only 10 inches above ground so gauge is ~5 inches from ground. June 28, 2016
Rated 4.0 out of 5.0 by MelnorFlow Meter with Shut-off The meter is easy to install but it didn't fulfill my expectations. I wanted this meter to be able to show how many gallons I was using when attached to my hose, and the online description gave me the indication this was a function of the meter, but it isn't. The meter only lets you set how many gallons to use at a single time. February 10, 2016
Rated 5.0 out of 5.0 by Good value I had previously used a mechanical timer. My local Home Depot doesn't stock them any more, but I found them online and had one delivered to the store. Twelve dollars later, I have something I can rely on. I had two digital timers fail on me, so I was really glad to find the mechanical one still available. The digital ones don't seem to be reliable, and they're much more expensive. July 7, 2015
Rated 3.0 out of 5.0 by worth the money This flowmeter works well, however I wish the adjustments were more precise, I would like to be able to decide to use exactly 50 gal, or water for exactly 15 min, it's a bit of a guessing game. But, when the meter is set to approx your desired amount it will stop the water, yes the water will stop so that's a great feature, can you believe it, it does what it claims and meters the water, yea. For the money I was happy enough. Con: No instructions, if you want to just use unlimited water then you must set device to MANUAL right between the 2 markings at the top, you'll figure it out.
