What does StellarGauge do?

StellarGauge connects to ultrasonic and pressure tank sensors and gives you live readings, low-level alerts, calibration tools and trend graphs from your phone or browser.

Is there a free plan?

Yes — single-tank monitoring with email alerts is free. Multi-tank dashboards, push notifications and historical analytics are on the paid tier.

Where is my data stored?

Data is stored in EU-hosted infrastructure under Perlicom Systems Ltd. We don't sell or share readings with third parties.

Live readings

Sub-minute updates from ultrasonic & pressure sensors. Open the app, see the level — no syncing, no delay.

Smart alerts

Push notifications when fuel runs low, when a sudden drop hints at a leak, or when battery on the sensor needs attention.

On-device calibration

Auto-calibrate from a fresh fill, or tweak manually with a tape measure. Works for vertical and horizontal cylindrical tanks.

Trends & reports

Daily, weekly, monthly burn-rate. Predictive reorder reminders so you're never empty in mid-winter.

EU data residency

Readings stay on EU-hosted infrastructure. No third-party trackers, no data sales — Perlicom Systems is the sole controller.

Multi-tank dashboard

Group several tanks across a home or site, share read-only access with installers, and export CSV for the accountant.

Ready when your tank is.

Install the app on your phone — set up takes about three minutes from sensor to first reading.
