Oil/Water Interface Meter


Interface Meter

The Interface Meter can be used in numerous applications including measuring oil and water levels in monitoring wells, detecting tank leakage and obtaining accurate measurements of water levels. When the probe is lowered down a well and contacts the product layer, a solid tone and green light alarm is activated on the reel. When the probe detects water, the tone begins to oscillate and the light changes to red.
