Wellntel Matches Pressure Transducer Performance

Resulting comparison between Wellntel and Pressure Transducer shows very high correlation between instruments

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,… Read more »

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 enter… Read more »

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. A factory technician may also suggest alternative sensor placement, special sounding tube… Read more »

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 lower… Read more »

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 our… Read more »

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 in… Read more »

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 upper… Read more »

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.

Falling or Cascading Water

Actively cascading water in a well is generally viewed as an unhealthy condition and should be corrected by a Well Service professional by adding a sleeve to stop the flow. However, where cascading is present, it will help to mount Wellntel on an access port fitted to a sounding tube. We’re happy refer a professional in… Read more »
