Condition-based
Rotating-electrode chlorine measurement unit
No fixed interval
No membrane or reagent is used. Inspect and clean the electrode and measuring cell when diagnostics indicate an issue.

Connected control and AI roadmap
ESP32-S3 Wi-Fi, BLE and explainable edge analytics are under validation.
Measurement Principles
Sensor Design Builds Confidence
Product pages provide model specifications and configurations; this page explains measurement principles and field advantages.
Rotating Electrode
Rotating-Electrode Chlorine
The electrode rotates during measurement to help limit surface fouling. There is no fixed-cycle membrane or reagent; the electrode and measuring cell are inspected and cleaned in response to diagnostics.
Reagent-free
Continuous measurement
No membrane
Lower fixed replacement burden
Within 2 min
90% response criterion
- Rotation helps limit contamination on the electrode surface
- Diagnostics guide electrode and measuring-cell inspection
- Field calibration plus 4–20 mA and RS-485 integration
Low-range Turbidity
Bubble-Reduced 90° Turbidity
A tungsten lamp and 90° scattered-light detector are paired with a detachable bubble-reduction stage ahead of the flow cell. The architecture is designed to reduce bubble interference in low-range monitoring at treatment plants and clearwells.

Scattered-light detection
- Detachable bubble-reduction stage for easier inspection and cleaning
- Accuracy criterion of ±2% or ±0.01 NTU
- Serviceable sample path and optical arrangement
Lifecycle & Maintenance
Consumable Life & Maintenance
Components with a recommended replacement interval are separated from condition-based items. Actual life varies with sample quality, flow, operating hours, cleaning and installation.
Recommended replacement
WBTU10 tungsten lamp
2 years recommended
Check light output and diagnostics; the lamp is user-replaceable.
Expected life
WBTU10 photodetector
5+ years
Contact Waterbee for inspection if detector performance is in question.
Recommended replacement
WBPH10 pH sensor
2 years recommended
Replace immediately if the glass electrode breaks; monthly calibration is recommended.
Recommended replacement
WBEC10 EC sensor
5 years recommended
Inspect contamination and measurement offset, then clean and calibrate before deciding on replacement.
Condition-based
Smart Filter-Drain element
By operating condition
Use differential pressure, upstream/downstream water quality and operating history to decide replacement timing.
These are maintenance recommendations, not warranted service-life values. Site conditions and the latest product manual take precedence.

Explainable Edge AI
R&D roadmap · not yet validated
Explainable AI & Safe Control
Waterbee is developing explainable lightweight analytics for abnormal water-quality signals and sensor drift. Training and validation run on a server, while the ESP32 performs risk-score inference only.
01
Data quality gate
Screen missing, stuck, out-of-range and simultaneous abnormal values first.
02
Robust anomaly detection
Apply explainable statistics such as Hampel, MAD, EWMA and CUSUM.
03
Lightweight risk inference
Deploy a validated shallow model to calculate a field risk score on the ESP32.
04
Independent safety control
A separate state machine enforces relay limits and recovery conditions.
Validation starts in shadow mode with no control authority. Only functions with demonstrated reproducibility and acceptable false-alarm behavior advance in stages.
