LR80 is ideal for corrosive liquids or solids and harsh outdoor or below-grade installations. It measures level height, tank volume, air gap, or open channel flow with zero dead band to maximize small tank capacity. Optional measurement through plastic or fiberglass tank walls makes it versatile, while the shielded 10m PVC cable ensures long-term durability.
