I’m thrilled with the accuracy of the Well Watch 670. When the pump installer set the pump two years ago, he documented the pump depth at 678 feet. At that time, we had a static level of 312 feet, and after pumping at 15 GPM for two hours, our recovery time was one hour. We thought we would never have a problem with using 6-7GPM for our home, garden, and small yard. However, the first time we tried watering the lawn with our automatic sprinklers, we ran the pump dry after about 2.5 hours. Our well output has decreased since then, giving us only about 1.5 hours of watering before we run dry. We have continued to have problems with water, and I bought your 670 to determine our current static level and recovery times.
As I reviewed my WSLOG000.TXT file, I identified three time periods where I ran the well dry. Because I set the logging time interval at one minute, I can be quite certain that I didn’t miss the maximum water depth by very much. During those 3 sample periods, the WW670 showed the distance to water as 678.85, 678.39, and 678.01 feet. If we can assume that the pump installer was 100% accurate in his recording of the pump depth and the pump turns off at that same depth (and I don’t know if either one of those is true!!) then your device is at least 99.9% accurate. Although $500 isn’t chump change, I’d say that you far surpassed your goal of making an affordable water-sensing device for homeowners like myself! Looking at the data from the log file, I can now calculate my watering and recovery times to stay within the production of my well.

We love data and we’ve gotten everything we wanted from the 670. We actually have it connected to our Scada system so we continuously monitor it and record a 5 minute history. Almost immediately we were able to change our pumping times. We actually found out (by mistake from a glitch in our controls) that we can run the well if needed for multiple days continuously without pulling the water level to the pump. We run it through Modbus and below is the data we collect. We also have a flow meter installed so I added graph to compare flow versus well depth, which I think you would like so I included that also. The graph below is from a day last month ago when we were cycling it a little more. Depending on the usage conditions I know now that my run cycles can be much longer. As you can see the well doesn’t drop much and the recharge rate is very quick. We have ran a tape down well twice to verify reading on separate occasions and both times we were within just a few inches of what the Well Watch was displaying. The pump on this particular well is set at 210ft.

First, thank you for a very useful quality product! It arrived a day early and I already have figured out what I need.
I spent hte afternoon taking depth measurements at known flow rates… I set a couple of hoses to the rate I wanted, then watched the level in the well until it settled, recorded and moved on. here is what i found:
Starting level = 95 feet
20 GPM 178ft – sucking air 46 pis
15 gpm 165ft steady 50 psi
10 gpm 137 to 140 ft 55 psi
5 gpm 120 to 124 ft 50 to 55 psi
0 gpm 110 ft very slight increase) 55 psi
this is with a variable speed well pump, which explains the psi readings and steady / fluctuating depth readings. The well is recorded at 180 ft… and air started entering the system at 176 ft. max depth i could draw was at 180 ft, and pretty soon the pump would lose prime.
So, what I learned is.. I am pulling WAY more water than i thought! But also.. I can now estimate the flow rate by depth of the well. I think that is close enough for my needs. Interestingly, the well report shows a steady 15gpm at 25 feet! but that was in april, when water levels are the highest.
Your product saved me a lot of trial and error, as we are installing a windmill and I need to know the depth at various flow rates.. plus I can now manage my irrigation zones based on well water depth.
One happy customer
Thanks!
We have found the Well Sounder to be an invaluable tool for a number of groundwater applications. It is especially useful for gauging water levels in residential wells; it is non-intrusive and eliminates the anxiety associated with placing conventional probes (water level gauges) into wells with pumps, pipes and wiring. We have found them to be accurate, easy to use and reliable for collecting data in the application of multi well aquifer tests. We have no hesitation in recommending this product to other groundwater professionals.
