KEY FEATURES

Accurate Water Tracking Wherever You Go 

Factory tank gauges are often unreliable especially on uneven ground or while travelling. The Topargee Bluetooth Water Tank Gauge uses precision flow-based monitoring to track water usage in real time giving you accurate readings directly from your smartphone.

No vague “full, half or empty” indicators. Just clear reliable water tracking so you can travel with confidence.
