The problem
Why this exists.
Farmers and rural communities depend on borewells but nobody knows how much water is left. Pumps run blindly, wells run dry mid-irrigation and damage motors, and overnight recharge goes unnoticed. Sensors dropped into the water corrode and are expensive to replace.
How it works
The operating principle.
EvaraDeep measures groundwater depth by sensing the tension in a string holding a floating bob. A motor lowers the bob until it reaches the surface; the string goes slack, a tension switch fires, and an encoder reports exactly how much string was paid out. Only string and bob ever enter the well.
01
Lower
A DC motor with an encoder pays out a string carrying a floating bob down the casing.
02
Detect
The instant the bob reaches the water it floats, the string goes slack, and a tension switch registers the release.
03
Measure
The encoder reports the exact length of string paid out. That length is the depth to water.
04
Retract
The motor reels the bob back up, leaving nothing submerged between readings.
05
Report
The depth is pushed to EvaraOne, building a live picture of drawdown and overnight recharge.

Questions
About EvaraDeep.
- How does EvaraDeep measure depth without a submerged sensor?
- A motor lowers a floating bob on a string until it reaches the water; the string goes slack, a tension switch fires and an encoder reports the length paid out. Only the string and bob enter the well.
- How deep can it measure?
- Up to 100 m, to within 1 cm, on borewells, deep tanks and sumps.
- Where is it mounted and how does it report?
- It top-mounts on the borewell cap and reports over 4G, NB-IoT, WiFi or LoRaWAN every 2 minutes, with up to 15 days of battery backup.
