Is this flowmeter accurate is it to let say 100 gallon how many gallons would a i be off by if any?

The one I have is fairly accurate. Measured water in a 5 gal bucket, but have not tried verifying using a container with measurement lines on it.

I don't think it is suppose to be accurate more of an estimation I think before the last cup. I know how much coffee I have by the amount of water I poured in.

no this unit is just a flow meter that will give you different outputs like GPM or just Total Gallons Liters ect.. I only used it to give me total gallons to see how much certain items held for water.

That is a typo. It should read ONE gallon. Thanks for the heads up. I'll pass it along to amazon to correct.

The gauge will not move until you get near he end. Keep pumping...takes 100-200 pumps if I remember right.

The meter only has a guage that reads, 0 to 2000 on top and 1 to 10 on the bottom of the line...I only paid less than $4.00 for the meter including shipping from China... It has saved me from over watering. The meter seems to be working ok but I don't know how accurate it is... For a cost of less than $5.00 it can't be too percise...

you just need to make sure its after a collector, if you have any. All of the exhaust needs to flow past this sensor, otherwise it will not be accurate. If you have dual exhaust, one side will be sufficient. My point is that you should try to get as much exhaust flowing past the center as possible so as to be as accurate as possible. Hope this helps!

Accurate? Probably not. It's manual states that its DC current accuracy is 3% +- 2 digits. But unless you get it calibrated you can't be sure of that.What kind of accuracy do you need? If you're considering this meter, it's probably good enough.

It works. Wasn't thoroughly impressed with it though. I'm sure on a 10 gallon it would be fine, just tune it down. Measure your KH and pH to find your perfect CO2 setting.

It says 100 ml treats up to 50 gallons of water so I would assume 2 would be too much. I use 100 ml for 46 gallons and the tank is sparkling and only water changes every 4 or 5 weeks

Gallons per minute output depends on the water pressure TO the unit. In my experience, the flow is unimpeded and output is equal to the normal flow of water through our kitchen pipe. I can't measure gallons per minute. I'd say our kitchen faucet runs normally - and strong. I have used these units since the 1980's and I love them. I'm really sad that they are no longer in production.

We have a 300 gallon coi pond. I really think we need a bigger filter. So this filter would just about right for 100 gallons. But this is only my opinion and I am not a fish pond expert.

While you need a therm/hydro meter in reptile tanks this particular item is worthless it isn't accurate what so ever. The hydro was reading 20% higher then what the tank actually was. AcuRite makes a digital therm/hydro meter that is less expensive then this.

Doesn't measure room humidity if that's what you mean. There is a dial to set relatively (like a slow to fast dial) how much humidity you want it to put out. The automatic shut-off only kicks in when the water level gets to almost empty.

Yes, within its accuracy. But remember it shows two numbers, the current flow and the total flow. The current flow reading erases after about 30 minutes of no flow. The cumulative flow remembers and adds to its previous total, so when you take a total flow reading you really have to have recorded the previous total flow reading to calculate the flow (unless you read the current flow number within that 30 minutes). Currently my unit has been monitoring pool consumption for about a month on the original battery. Not sure yet how long the battery will last.

Do not know any way to estimate usage -- best suggestion would be to keep a backup cylinder at hand, or buy a gauge for your tank.

If what you mean is will it turn on/off based on temperature then no. You could buy a aquarium heater controller and hook this up to it and it would do so, but for what you want it may be "overkill". I would suggest that you just turn it on and off manually if you want to use this for your purpose. BTW, the number 240 is the number of gallons per hour (gph) this flow head will create...might be MORE circulation than you expect.
