About
How Does It Work?
The Well Bubbler forces compressed air through a tube installed in the well to accurately measure the standing and pumping water levels - the same approach used by well drillers and pump installers. The well level is automatically calculated from the length of the tube and the air pressure, and is shown on the display in feet. The Well Bubbler is designed and built in California.

The US Geological Survey (USGS), Iowa Department of Natural Resources (DNR) and University of Missouri recommend using compressed air, and an airline, to manually measure well water level. The Well Bubbler performs the same test automatically!
BENEFITS
Ease of Installation
The Well Bubbler was developed after years of struggling with hydro-static, "pressure-type", and acoustic well level sensors. Submersible pump motor wiring and tight clearances cause hydro-static sensors to snag during installation. Turbine pump motors drip oil into the well, clogging and fouling the sensor. The pump can be damaged by "swallowing" the sensor body and wiring, while VFD noise can make pressure sensors unreadable. Splashing water during well recharge, deviated well geometry, and engine noise affect the accuracy of acoustic sensors. The Well Bubbler can be safely installed with all pump and motor types - it is not affected by oil in the well, VFD noise, or engine noise.

The Well Bubbler uses built-in solar power and requires no wiring, assembly AC power. In many cases, a 1/4" air line is already installed in the well, for a truly "plug-and-play" installation.
FEATURES
Plug-and-Play Operation
Each Well Bubbler 10-120 includes the following features as standard, allowing for accurate, reliable well level measurement out of the box.
- Cellular data reporting and text alerts
- Record flow rate from pulse-type flow meters
- Record pump power & pressure using 4-20mA sensors
- Built-in solar power - no wiring, assembly or AC needed
- LCD display - visible in bright sunlight, and at night
- Relay output - stop the pump when level is low
- Secure data logger - view well level & flow rate history
- Telemetry output - 4 to 20mA and 0 to 5Vdc
- Use with standard, 1/4" diameter air tubing
- External power input - for remote solar panels or AC
- External power output - used to power flow meters

ACCESSORIES
The following optional Well Bubbler accessories aid in sensor and air line installation.
Air Line Kit
Use the air line kit for wells without an existing air line. Our tubing has a small 5/32" outer diameter, a 1/2" bend radius and is rated for 350 psi for ease of installation and long service life. The kit includes a set of push-to-connect fittings for use with the Well Bubbler.
Weight Bead Kit
The weight bead kit is used with our 5/32" diameter air line. The beads have a small 3/8" diameter, a 1/2" length, and are used to weigh down the tubing during installation. They are made from soft, zinc-plated brass and include all fittings required for installation. Combined with food-grade lubricant, the flexible, small-diameter assembly can be installed in the tightest wells with minimal access; the beads and fittings are designed to separate from the tubing if stuck.
Tubing Caddy
The tubing caddy makes frequent installations convenient and accurate. Carry up to two, 1000-foot spools 5/32" tubing. The caddy includes a precision tubing length counter, showing the exact length of tubing installed in the well.
Mounting Kit
The Well Bubbler is designed for mounting on open-face 1-5/8 structural strut channel. The strut can be mounted directly in the ground, to a backboard or a concrete pump pad. The mounting kit includes a 12" section of strut, with fasteners. Contact us for longer sections of structural channel, fittings and fasteners.

Well Bubbler accessories are sold separately from the unit, and are used in wells without an existing air line.
