Tank level indicator alarms are set at which high and low levels?

Explanation:
Tank level alarms are set to give timely warnings so you can act before you reach a dangerous condition—either overflowing or running out of fuel. The high-level alarm should be near the top, but with some headroom to prevent overflow and to allow the fill system to shut down safely; around 95% provides that margin. The low-level alarm should trigger well before empty, giving enough time to switch sources, start pumps, or stage a refill, so about 25% leaves a healthy reserve while still warning you early. This combination balances timely notification with safe operating margins, making it the most practical choice.
