 Solinst Model 122/Mini 122 

Interface Meter


Available from GroundwaterSoftware.com, Solinst Oil/Water Interface Meters give clear and accurate measurements of product thickness and level in wells and tanks. 

Determination of both light (floating) non-aqueous phase liquids (LNAPL) and dense (sinking) non-aqueous phase liquids (DNAPL) is quick and easy. The factory-sealed probes are pressure proof and tapes are available in a range of lengths from 65 - 1000 ft (20 - 300 m) for easy measurement of product thickness, both of LNAPL and DNAPL..

Solinst 122 Water Level Interface Meter Operating Principles


Product (Non-conductive liquid) = Steady light and tone 

Water (Conductive liquid) = Intermittent light and tone 



To detect liquids, Solinst Interface Meters use an infra-red beam and detector. When the probe enters a liquid the beam is refracted away from the detector which activates an audible tone and light. If the liquid is a non-conductive oil/product the signals of the oil/water interface meter are steady. If the liquid is water (conductive liquid greater than 50 μS/cm), the conductivity of the water completes a conductivity circuit. This overrides the infra-red circuit, and the tone and light are intermittent from the oil/water interface meter. Both sensors use exactly the same zero point, giving accuracy as good as 1/200 ft or 1.0 mm. The high accuracy enables the sensors of the oil/water interface meter to detect the slightest sheen of oil on the surface of the water and to measure both LNAPL and DNAPL accurately. This is indicated by a rapid intermittent tone and therefore provide optimal measurement of product thickness. 

Solinst 122 Water Level Interface Meter Model 122 Mini

The Solinst 122 Water Level Interface Meter 122 Mini is a convenient small version of the Solinst 122 Water Level Interface Meter, small enough to fit in a backpack. Both are available from GroundwaterSoftware.com, A custom carrying bag is also an option. The Mini is available in 80 ft or 25 m lengths. The 5/8" (16 mm) diameter probe is attached to narrow 1/4" (6 mm) tape, which is accurately marked each 1/100 ft or millimeter. Enhanced electronics allow operation for up to 300 hours of on-time, using one 9V battery.
