Our selection of Heron portable water level tools and interface meters are perfect for routine checking of water levels and the thicknesses of a floating layer of light non-aqueous phase liquid (LNAPL) in wells when technicians are on site. When used with our other tools for measuring groundwater, such as water quality meters and data loggers, these portable water level devices help provide site information quickly and efficiently.

Browse our expanded collection of Heron water level tools below, which include meters with precisely marked measurement tape, durable reel, water resistant probes, and reliable electronics, to efficiently detect the depth to water’s surface, or thickness of a floating petroleum layer.

H.Oil Oil-Water Interface
Availability: In Stock

Interface Meters are used to measure the depth to the top of a petroleum layer and the depth to the top of the water surface. As the probe is lowered in the well a light diffraction cone senses contact with the top of the floating petroleum layer (LNAPL) and produces an audible and visual alarm on the reel at the surface. When the probe is lowered through the floating layer, water sensing electrodes detect contact with the water surface and create a different audible and visual alarm. Depth to...
