For best performance: factory upgrade to latest technology


What Does It Offer?

Get both Sensor Firmware V2 (SV2.1) and SP4 Sounder in one fast Factory Upgrade!

We'll send you a label. Send us your Sensor and we'll inspect it, upgrade its firmware to our powerful new SV2.1 package, refresh worn components and replace the sounder with the latest SP4 technology. 

Turnaround: 1 week from arrival at the factory.

You will be charged a total of $150; $131 for the upgrade and $19 for round-trip shipping.

What is SV2.1?

1.) SV2.1 sensor firmware offers two new modes of operation: Once Daily Recovery and Pump Influence.

  • Once Daily Recovery provides insights into pumping recovery performance in a well while also saving battery life.
  • Pump Influence is a new reading type that notes if the pump is running when a timed reading is taken (requires a Pump Performance Kit to work, included in all +Pump kits and new Basic kits shipped as of 2/6/2018, and FREE with this upgrade.)

Contact for installation support or for assistance setting modes.

2.) SV2.1 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, improves dataset consistency, minimizes false alerts, and reduces future sensor attention. You get great results faster, they last longer, and are more useful in networks.

What's an SP4 Sounder?

SP4Sounder Probe 4 (SP4), a technical advancement that improves operation and performance even in wells in places with high seasonal temperature variation and very cold cold. It is a significant preventive addition to any Wellntel system.

Wellntel is engineered for rugged conditions, including intense sun, hot and cold temperatures, and, of course, water. Components are selected for long life and stable operation despite a wide range of conditions. Our plastic is UV-stable. Our electronics are encapsulated. Everything needing to be outside is waterproof and cold and hot-tolerant. That said, in the volatile humidity and temperature changes in spring and fall can effect performance. By sealing the sounder and replacing solid surfaces with slick, flexible ones, and while not inhibiting pressure and sound, SP4 will continue to operate when soaked by dew and will recover from temporary periods of icing. 

Finally, with SP4, we will provide a custom-to-your-well sounding probe that will maximize the Date Delivery Rate from your system. A customer service representative will coordinate that customization with your when your upgrade order is received.

*Data Delivery Rate (DDR) is Data Delivery Rate (DDR) is a metric measuring the percent of the total reading events triggered by the sensor that are able to capture the water level based on sensor measured statistics associated with raw data and using the Wellntel plausibility engine. High DDR depends on latest firmware, SP4 and a properly sized sounder.
