In a side-by-side comparison with a combination pressure transducer and barometric pressure logger, Wellntel has shown that with proper calibration and “benchmarking,” Wellntel will deliver accuracy and precision on par with much more expensive and complicated instruments. Here are the results of a three-month study conducted by members of the South Benton County Community Groundwater Network,Continue reading “Wellntel Matches Pressure Transducer Performance”

Wellntel Announces Sensor Firmware V2 (SV2)
Today, Wellntel is announcing Wellntel Sensor Firmware V2 (SV2). This new firmware is important in two ways: 1.) It substantially improves the ability of an out-of-the-box sensor to find and track groundwater levels with little or no calibration in a wide range of physical and acoustic well conditions, and when situations in the field change. Therefore, it simplifies start-up, improvesContinue reading “Wellntel Announces Sensor Firmware V2 (SV2)”
Very Shallow or Very Deep Water
Wellntel will work on wells as deep as 1600 feet, but the Factory Default Settings are designed for a range of water depths that are commonplace around the world: between about 50 and 600 feet to water. If you are aware that your well is shallower or deeper than that, take a minute to enterContinue reading “Very Shallow or Very Deep Water”
A Sounding Tube is in the Well
Wellntel can be configured to work through common sounding tubes, and indeed, they are usually a solution to other conditions. But sounding tubes themselves may require special calibrations and hardware adaptations. It is important to make sure that sounding tubes are well vented and are as large as possible. A factory technician may also suggestContinue reading “A Sounding Tube is in the Well”
Variable Frequency Drive runs the Pump
Sometimes the presence of a Variable Frequency Drive (VFD) can create noise conditions in the wall that interfere with Wellntel’s signal. In some rare cases, a VFD can create a pattern of mixed results. First, make sure to install the PPK included in your +Pump Wellntel Kit. Second, a Wellntel technician may recommend higher or lowerContinue reading “Variable Frequency Drive runs the Pump”
Milled Slot in Casing Pipe
Where there is “milled slot” or a perforated casing seeping gravel or sand, caverns can form outside of the casing. These structures can attenuate or degrade signals. How can you tell? Your well construction report will tell you, and if you’re not sure how to read it, feel free to forward a copy to ourContinue reading “Milled Slot in Casing Pipe”
Dry Cavern in a Fractured Rock Well
Where there are dry caverns or harsh fractured rock, it is best to mount Wellntel on an access port fitted to a sounding tube. In this case, the sounding tube contains the signal and enables successful readings. Wellntel recommends a sounding tube be installed by a qualified well servicer as a matter of practice inContinue reading “Dry Cavern in a Fractured Rock Well”
Sealed Well-cap or Insufficient Airflow in the Well
Insufficient venting will hobble a Wellntel sensor and damage done from the condition is not covered by warranty. Wellntel offers an optional 1/2” NPT tee fitting and sanitary vent that can provide air flow when none exists, or it is found to be insufficient for reliable readings.
Constrained Space at the Wellhead
When you don’t have room over the well cap (because it’s under your deck or front porch), Wellntel offers an optional long lead kit that allows the lower and upper units to be mounted separately: the lower can goes inside the well (or on the cap or seal if there is room) and the upperContinue reading “Constrained Space at the Wellhead”
Stucco or Metal Buildings
Wellntel offers an optional mounting kit — wire and brackets — to move the Gateway antenna outside of a stucco or metal clad building, which will interfere with radio transmissions between the Sensor and Gateway.
