Tank Level Indicator (no electricity required)

Tank Gauge — Reliable Cistern & Rain Tank Level Monitor (No Electricity Required)

We've used several cistern gauges over our years of installing rainwater harvesting systems, and we keep coming back to this one — the Tank Gauge Tank Level Monitor. It's our go-to when we want a reliable, no-fuss gauge that doesn't depend on electricity or batteries.

Simple and easy to install, the Tank Gauge fits all vented tanks up to 100" in height. It features an easy-to-read dial and uses a weighted float suspended on a string line for accurate readings. Mounts to the tank with two included screws.
