Oil/Water Interface Meters

Back in 1995, Heron Instruments’ founder Donald Toon created our first oil/water interface meter, the H.OIL. Fast forward 25 years to 2020, and we continue to make the most accurate and rugged interface meter in the world.

Heron oil/water interface meters are used to measure the interface levels between two liquids in the same tank, vessel, well or aquifer. The probe can easily and accurately detect floating product (LNAPL), sinking product (DNAPL) and water with different audio and visual indicators.

Heron Instruments meters can be used for the accurate detection of leaking hydrocarbons like fuel or oils from tanks or any vessel into the groundwater supply.
