Storage Monitoring
Tank Level + Temperature + Leak Telemetry
The water storage monitoring system is a 2-kilogram, 5-watt telemetry suite that tracks fluid levels, temperatures, leaks, and microbial indicators across settlement storage tanks. Using cross-checked capacitive probes and load cells, the assembly maintains 1% level accuracy alongside PT1000 RTDs and acoustic leak detectors capable of registering losses down to 5 grams per hour. Operating in the lunar radiation environment requires radiation-tolerant sensor electronics, while an intended 20-year lifetime with a 150,000-hour mean time between failures necessitates calibration drift compensation and sensor redundancy to prevent single-point faults.
Telemetry suite monitoring all storage tanks (level, temperature, leak, microbial indicator) for inventory tracking and anomaly detection.
Purpose
Telemetry suite monitoring all storage tanks (level, temperature, leak, microbial indicator) for inventory tracking and anomaly detection.
